Preface

Preface



S E C T I O N 1

ISOGEN contains a large number of variable features, such as isometric type and drawing size, dimensional units, line weight, BOM position on the isometric drawing, and so forth. These and other features are controlled by user-defined option switch settings. A total of 140 option switches are available, many of which have several positions or settings.

Option switches give you a high level of configuration that allows you to tailor both drawings and material lists to your exact needs, including control of:

Isometric type – Fabrication and construction; fabrication only; construction only; individual spool isometrics; multi-pipeline system isometrics

Graphic output options – DXF, DWG

Drawing size – Metric A series, American ANSI sizes, or special sizes

Viewpoint orientation – Indicated by a north arrow

Dimensions – Standard string, overall, pipe supports, and to valve centers

Drawing frame – User-designed or standard

Text – Large, medium, and small

For many option switches, a switch detail sheet is available in the Appendix of this document. The switch detail sheet provides additional information regarding how a specific option switch setting impacts isometric drawing output. If a detail sheet is available, it is listed under Option Switch Detail Sheet.at the end of the option switch topic:

Option Switch 2: Cut Piece Numbering/List Type Controls the generation of the cut piece list and corresponding cut piece identifiers (numbers or letters) at appropriate positions along the plotted pipeline. An option to have cut piece identifiers (numbers or letters) starting at 1 or A on each isometric drawing as opposed to each pipeline is also controlled with this option switch.

Cut piece numbers can be output on the isometric drawing in a variety of alternative enclosure types which are controlled by switch positions 7 and 8.

There are two types of cut piece lists: the old style, which has limited information, and the new style, which has full information.

Finally, when using imperial units you have an option to list the cut lengths on the new style cut piece list in a decimal inches format. This option is in addition to the regular value in the LENGTH column.

Switch Settings

Option Switch 6: Date Output Controls the date format that is output on the isometric drawing and printed listings in a 2- or 4-digit year format. By default, the actual date that the software outputs is taken from either the PDF (pipeline data file) that is created by the host 3D design software or the computer system at the time the drawing is generated.

There are three format options plus an option switch setting to suppress any date output, even though a date exists in the IDF.

Switch Settings


SWITCH POSITIONS 1 and 2 - Date Output and Format

0 1 2 3 10 11 12

Option Switch 7: Pipeline Splitting (User Control) Identifies the method used when splitting two pipelines into multiple isometric drawings. Two methods are available:

Automatic: This method automatically calculates the number of pipeline graphics that can be displayed on the selected drawing size, and then generates the exact number of isometric drawings that are required to contain the completed pipeline.

Fixed: This method requires that you specify the number of isometric drawings that are necessary to display the completed pipeline.

The setting in Position 1 is ignored if manual pipeline split points are present in the piping data file (PDF).

Since any option switch setting applies to all the pipelines in a run, it is recommended that you only use the fixed method in special cases for single pipeline runs.

An added option permits any drawing split points input in the 3D model by the user and present in the PDF to be ignored.

Switch Settings


SWITCH POSITIONS 1 and 2 - Various Controls

0 Value

Use automatic splitting to control the number of isometric drawings that are required. Set the number of isometric drawings that are required.

Option Switch 8: Dimension Line Standout Controls dimension line standout distances for the following:

String and composite dimensions that are normally plotted as the middle layer of multi-layer dimensions.

Dimensioned messages, support messages, and reference dimensions on the inner layer, but only when a standout distance in Option Switch 40 is not set.

Overall dimensions on the outer layer, but only when a standout distance in Option Switch 118 is not set.

Values that are less than or equal to 11mm are ignored by the software and substituted by the appropriate standard dimension line standout distance. When the option switch value is greater than 11mm, the software uses that value to set the dimension line standout distance for string and composite dimensions on the middle layer. The inner dimensioned layer for dimensioned messages, support messages, and reference dimensions are then set to be 0.5 times this distance, while the outer layer overall dimensions are set to 1.5 times this distance.

Dimension text and messages are placed along a section of pipe in isometric projection (oblique angle or slanted text).

This feature is only available for DXF format output styles generated using the piping object data (POD) interface.

Text oblique angle is adjusted to be parallel to the dimension standout direction.

When it is practical to do so, ISOGEN attempts to set a vertical dimension standout for horizontal sections of pipeline

Switch Settings


0 Value

Plot standard dimension line standouts. This is the default setting. Set the required standout distance (in whole millimeters), for string and composite dimensions on the middle layer.

The standard dimension line standout distances for the various drawing sizes are as follows:

Small-sized drawing text (Option Switch 4, Position 1)

String/composite dimension standout - 12mm.

Messages, support and reference dimension standout - 6mm.

Overall dimension standout - 18mm.

Medium-sized drawing text (Option Switch 4, Position 0)


Message, support and reference dimension standout - 7mm.

Overall dimension standout - 21mm

Large-sized drawing text (Option Switch 4, Position 2)

Appendix: Option Switch Detail Sheets



Plotfile Length (OS 1) Option Switch 1 only operates on plotters that use a plot roll rather than single sheets, and when OS 31 is set at 0 to obtain multiple isometrics in each plotfile such as that shown in the following illustration.

OS 1 is not effective if OS 31 is set to 1 so that each plotfile contains only a single isometric. As a result, it is not used when single DXF or DGN plotfiles are produced for importing into a 2D graphics system, such as AutoCAD or MicroStation, where isometric drawings are usually sent to a laser printer for plotting.

Some older plotters, such as Benson Electrostatic, have a maximum plotfile length of 3275mm, which is the default setting for OS 1. Other similar plotters use a different maximum length value. Under these settings, the software considers the physical drawing size and stacking arrangement and will output the maximum number of isometrics it can into each plotfile produced. For example, if 20 isometrics are produced, you can get three plotfiles--two containing three isometric drawings each and one containing four isometric drawings.

See Also Option Switch 1: Plotfile Length (on page 12)



Cut Piece Numbering/List Type (OS 2) In the following example, cut piece identifiers are depicted as numbers enclosed within brackets (<1>). This is the default setting of OS 2 Position 3. Also shown is an example of the "new style" Cut Piece List, which results from OS 2 Position 2 = 1.

Drawing Trim Marks (OS 3) As with OS 1, the facility provided by OS 3 is beneficial only on plotters that use a plot roll rather than single sheets. Drawing trim marks are plotted at the extremities of each isometric drawing, or the distance away from the frame being the margin settings. Trimming to the marks provides the exact drawing size.

These switch settings retrieve the date entry from your computer on the day of processing:

The word DATE is in AText -250.

Month names are in ATexts -258 and -269.

Use the ISOGEN -14 record to position the date with text positioning (TEXTPOS).

See Also Option Switch 6: Date Output (on page 20)



Pipeline Splitting - User Control (OS 7) Use the default setting, OS 7 = 0, for automatic drawing splitting.

Although the amount of information on each drawing is controlled by the software, it can be increased or decreased by using Option Switch 38 (see "Option Switch 38: Pipeline Splitting (Automatic)" on page 62).

Alternatively, you can override automatic splitting by setting the switch value to the required number of drawings. For example, for two drawings use OS 7 = 2.

Drawing Margins (OS 10, 11, 12, & 13)

These margins must be set when using either of the following:

The standard ISOGEN drawing frame

A user-defined drawing frame

You must set the right- or left-side margin to suit the width of a Style 3 or Style 4 BOM.

See Also Option Switch 10: Drawing Margin (Left) (on page 27) Option Switch 11: Drawing Margin (Right) (on page 28) Option Switch 12: Drawing Margin (Top) (on page 29) Option Switch 13: Drawing Margin (Bottom) (on page 30)



Drawing Size - Standard and PostScript Plotter Size (OS 14)

OS 14 sets standard drawing sizes, which includes all the European 'A' series paper sizes and the American ANSI sizes ('A' to 'E').

For non-standard drawing sizes, use Option Switch 15 (see "Option Switch 15: Drawing Size (Height)" on page 33) and Option Switch 16 (see "Option Switch 16: Drawing Size (Width)" on page 34).

Switch positions 3 and 4 permit direct PostScript files to be plotted at a reduced scale, as shown in the following illustration:

You can also achieve this effect by plotting out of a 2D graphics system, such as AutoCAD or MicroStation.

See Also Option Switch 14: Drawing Size (Standard Postscript Plotter Size) (on page 31)



Drawing Size - Height and Width (OS 15 & 16) These option switches are used to set non-standard drawing sizes. For example, for a drawing that is 300mm x 400mm , set OS 15 = 300 and OS 16 = 400.

Any settings in OS 15 and OS 16 will cause the settings in OS 14 Positions 1 and 2 to be ignored. However, settings in OS 14 Positions 3 and 4 are not ignored. This means that "direct' PostScript files of a non-standard drawing size can be produced at a reduced scale in the same way that standard drawings can be.

See Also Option Switch 15: Drawing Size (Height) (on page 33) Option Switch 16: Drawing Size (Width) (on page 34)



Flow Arrows - On Components (OS 17) The arrow direction, as well as the fluid flow or gas flow direction, is controlled by the 3D design system. When you set OS 17 = 0, most normal in-line components will have the flow arrow plotted alongside.

An alternative type of flow arrow that is plotted directly on the pipe is available. For more information, see Option Switch 112: Flow Arrows (Pipeline) (on page 172).

See Also Option Switch 17: Flow Arrows/Gaskets (Components) (on page 35)



Drawing Frame - Program Standard (OS 18) Option Switch 18 allows you to turn on and off the standard ISOGEN drawing frame. In example A, the drawing frame is turned on (OS 18 = 0). This is the default setting. In example B, the drawing frame is turned off (OS 18 = 1).

The standard drawing frame is always turned off when you are using a user-defined backing frame.

See Also Option Switch 18: Drawing Frame (Program Standard) (on page 36)



Sloping Pipeline Indication Method (OS 19) The following example shows how a falling pipeline is indicated on the isometric drawing. The default setting of 0 shows the fall angle in degrees.

You can use setting values 1 through 5 to display the fall in alternative ways. A value of 6, however, suppresses the fall indication altogether, as shown in the following example:

See Also Option Switch 19: Sloping Pipeline (Indication Method) (on page 37)



Sloping Pipeline Indication Limit (OS 20) Option Switch 20 works in conjunction with Option Switch 19 to set the cut-off value that determines the steepness of slope that should be shown as a fall.In the following example, the cut-off value for the pipeline is set to 5-degrees.

In the next illustration, the cut-off value for the same pipeline is set to 4-degrees. Because the actual slope is now steeper than the cut-off value, the slope is shown as follows:

Material List - Controls & M/C File Type (OS 23)

Style 1 Material List (OS 23 = 100)

This is the standard style of BOM. It has fixed content and layout. It does not require an MLD control file.





Material List – Controls & M/C File Type (OS 23)

Special Type Material List (OS 23 = 110)

Used by Siemens. This is a variation on Style 1, and does not require an MLD control file.







Although it has the overall appearance of a Style 1 material list, this style of BOM has user-defined content and layout. It requires an MLD file.







Uses alphabetic pointers. Requires an MLD control file.







Uses a completely different concept to Style 1 or Style 2. This type of material list is plotted onto a user-defined backing sheet where each BOM entry is positioned at a specific X-Y coordinate position. Requires an MLD control file containing basic X-Y coordinate details.







Same concept as Style 3 but this material list also shows material usage for each spool. Like Style 3, this style of material list requires an MLD control file containing basic X-Y coordinate details.







In this style of material list, there are no sub-headings and the BOM is partitioned into groups. Requires an MLD control file.






Standard Material Control File Output (OS 23 Position 4 = 0)

This output can be loaded into the material control system. This is the older, original style, which contains fixed, non-user-defined information






User-Defined Material Control File Output (OS 23 Position 4 = 1)

This type permits variable content and layout, but it requires an MLD file. This output can also be loaded into the your material control system.

See Also Option Switch 23: Material List (Controls/File Type) (on page 43)



Material List - Pipeline/Drawing (OS 24)

Option Switch 24 Position 1

Controls whether material lists are produced by the following:

OS 24 Pos 1 = 0 - Drawing

OS 24 Pos 1 = 1 - Drawing

OS 24 Pos 1 = 2 - Drawing (spool isometric material part numbers match full isometric material part numbers)

OS 24 Pos 1 = 3 - Pipeline (spool isometric material list numbers match full isometric material list numbers)

However, this is only relevant on split isometrics that have more than one drawing as illustrated by the following examples.

Example 1

OS 24 Pos 1 = 0 - Produces the material list by drawing

OS 24 Pos 1 = 3 - Produces the material list by drawing. Appears in this form on both full and spool isometrics; all part numbers match.





Material List – Pipeline/Drawing (OS 24)

Example 2:

OS 24 Pos 1 = 1 - Produces material list by pipeline.

OS 24 Pos 1 = 3 - Produces the material list by pipeline, which appears in this form on both full and spool isometrics; all part numbers match.





Material List – Pipeline/Drawing (OS 24)


Controls the way pipe lengths are reported on the BOM. There are three styles each for metric and imperial length.

See Also Option Switch 24: Material List (Pipeline/Drawing/Pipe Length Units) (on page 45)



Material List - Position (OS 25)


Controls the location of where the BOM is plotted, either on the left-hand (A) or right-hand (B) side of the isometric drawing.

This option switch setting affects only Style 1 and Style 2 material lists, not Style 3 and Style 4.





Material List – Position (OS 25)


Controls where the title block is printed relative to the BOM on the isometric drawing. Any of the following is possible:

Positioned in the bottom right-hand corner. This is the default position. (OS 25 Pos 2 = Blank)

Printed at the bottom of the BOM. (OS 25 Pos 2 = 1)





Material List – Position (OS 25)

Suppressed completely. (OS 25 Pos 2 = 2)

See Also Option Switch 25: Material List Position/Title Block Position (on page 47)



Material List - Descriptions (OS 26) Set to OS 26 = 0 to suppress item descriptions only applies to style 1 BOM because this function is controlled from the MLD for all other styles (2, 3 and 4).

Set OS 26 = 11 with Style 1 BOM for the following:

See Also Option Switch 26: Material List (Descriptions) (on page 48)



Material List - Text Size (OS 27) Controls the text size for all generated characters in the region of the isometric highlighted with the red box.

See Also Option Switch 27: Material List (Text Size) (on page 49)



Material List - Item Code Length (OS 28) Option Switch 28 controls the number of characters ISOGEN uses for the material list item code. In the following example, since the longest item code is 13 characters, OS 28 = 13.

See Also Option Switch 28: Material List (Item Code Length) (on page 50)



Material List - Line Spacing (OS 29) You can use Option Switch 29 to control the line spacing distance on the plotted material list, thereby making the BOM listing look shorter or longer. The option switch setting represents the percentage of the original, or default, size. Example A depicts the full length BOM list, which is 100% of its default size (OS 29=100). Example B, however, depicts the same BOM list at 90% of its default size (OS 29=90).

See Also Option Switch 29: Material List (Line Spacing) (on page 51)



Material List - Continuation Method (OS 30) Set OS 30 = 0 to cause the BOM to overflow onto a second material list plotted alongside the first, creating a wider, non-standard drawing size:

Set OS 30 = 1 to cause the BOM to overflow onto a second dummy isometric drawing that contains the overflow material list, but not the pipeline graphics. The isometric drawing is assigned the next drawing sheet identifier in the sequence, as shown in example B of the following sets of illustrations.

Setting OS 30 = 2 produces the same BOM overflow output as Position 1. However, the isometric drawing identifier of the overflow sheet is suffixed with the letter A, as shown in the following example:





Material List – Continuation Method (OS 30)

Set OS 30 = 10 to cause any single sheet isometric to be called 1/1:

See Also Option Switch 30: Material List (Continuation Method) (on page 52)



Drawing Output - File/Screen (OS 31) Set OS 31 = 0 (and OS 1 = 3275) to place multiple isometrics all in one plot file. This is the most economical method when the plot files are going to a paper roll type plotter.

Set OS 31 = 1 to place each isometric in a separate plot file. Use this option when plot files are in DXF or DGN format for loading into a 2D graphics system or when plot files are going to a laser printer.

Set OS 31 = 2 to send the isometric directly to the screen.

This option does not work on a PC.

See Also Option Switch 31: Drawing Output (File/Screen) (on page 54)



Drawing Output - Scaling (OS 32) Set OS 32 = 0 or OS 32=100 to generate full-sized isometric drawings. This is the default setting.

The following example shows the isometric drawing generated in the previous illustration at 71% of its original size. To produce this result, set OS 32=71.

Similarly, to generate an isometric drawing at 50% of its original size, set OS 32=50.

When you use this option switch, the entire isometric (frame and inner contents) is rescaled.

If you are using a 2D graphics system, such as AutoCAD, and you want to produce scaled down isometrics (for example, effectively A2 size - but scaled down to A3 on the output), then that reduction should be done in the graphics system, not with this option switch.

See Also Option Switch 32: Drawing Output (Scaling) (on page 56)



Drawing Output - Picture Scale (OS 34) Set to OS 34 = 0 or OS 34=100 to produce normal picture scale, which is the default setting.

Set to OS 34 = 150 for 150% of the nominated drawing size.

Unlike OS 32, this option switch only changes the drawing part of the isometric. Everything else remains the same size.

See Also Option Switch 34: Drawing Output (Picture Scale) (on page 58)



Drawing - Reserved Areas (OS 35) The reserved area is a distance setting which must always be in millimeters, even if you typically use Imperial units. The following example shows the reserved area distance for the drawing region (A) and the reserved area distance for the material list (B).

See Also Option Switch 35: Drawing (Reserved Areas) (on page 59)



Drawing Output - Stacking Value (OS 36) Set OS 36 = 0 or OS 36=1 for single stacking.

Set OS 36 = 2 for double stacking.

Like Option Switch 1 (see "Plotfile Length (OS 1)" on page 207), this option switch only operates on plotters that use a plot roll rather than single sheets and where OS 31 = 0 to obtain multiple isometrics in each plot file as shown above.

See Also Option Switch 36: Drawing Output (Stacking Value) (on page 60)



Drawing Output - Stacking Orientation (OS 37) Set OS 37 = 0 to orient the drawings along the plot roll.

Set OS 37 = 1 to orient the drawings across the plot roll.

As with Option Switch 1 (see "Plotfile Length (OS 1)" on page 207), this option switch only operates on plotters that use a plot roll rather than single sheets and where OS 31 = 0 to obtain multiple isometrics in each plot file as shown above.

See Also Option Switch 37: Drawing Output (Stacking Orientation) (on page 61)



Pipeline Splitting - Automatic (OS 38) Set OS 38 = 0 or OS 38=100 (the default value) to generate drawings that have the software designated optimum amount of information. The result is two drawings, each with approximately equal amounts of information.





Pipeline Splitting –Automatic (OS 38)

Set OS 38 = 120 to force more information onto each drawing. The result is a single drawing, as shown in the following example:

Specifying values greater than 100 may produce drawings that contain too much information to be easily read. You take full responsibility for the output that results when using large values.

See Also Option Switch 38: Pipeline Splitting (Automatic) (on page 62)



Spool Piece Identifiers (OS 39) Set OS 39 = 0 for a numeric type automatic spool piece identifier.

Set OS 39 = 2 for an alphabetic type automatic spool piece identifier.





Spool Piece Identifiers (OS 39)

User-defined spool identifiers can be entered in the model by the 3D designer, or they can be probed in using SPOOLGEN.

Set OS 39 = 0 to output the following spool identifier:

The alternative enclosed types listed in the following table are controlled by Option Switch 39 Position 3. These are all obtainable with either automatic or user-defined spool identifiers.

OS 39 Pos 3=1

OS 39 Pos 3=2

OS 39 Pos 3=3

OS 39 Pos 3=4

OS 39 Pos 3=5

OS 39 Pos 3=6

OS 39 Pos 3=7 10 SPL A

OS 39 Pos 3=9





Spool Piece Identifiers (OS 39)

Option Switch 39 Position 4 controls how spool drawings are identified. Set OS 39 Pos 4 = 0 to prefix the pipeline reference to the spool identifier.

Set OS 39 Pos 4=1 to output the pipeline reference as the spool identifier.

See Also Option Switch 39: Spool Piece Identifiers (on page 64)



Pipe Supports (OS 40) Set OS 40 = 0 for string dimensions for pipe supports.

Set OS 40 = 1 for overall dimensions for pipe supports.





Pipe Supports (OS 40)

Set OS 40 = 2 to suppress pipe supports.

Set OS 40 = 3 for pipe supports drawn but not dimensioned.





Pipe Supports (OS 40)

Set OS 40 = 10 for pipe support dimensions on the opposite side.

Set OS 40 = 2500 for pipe support standout distance to equal 25mm. This forces the standout outside the normal dimension.

See Also Option Switch 40: Pipe Supports (on page 67)



Bore/Dimension/Weight Control (OS 41) Set OS 41 = 0 for mixed units.

Set OS 41 = 1 for imperial units.

Set OS 41 = 2 for metric units.





Bore/Dimension/Weight Control (OS 41)

Set OS 41 Pos 2 = 1 for metric coordinates output in M.mmm format.

Set OS 41 Pos 3 for feet and inch output format, including stacked fractions.

Stacked fractions only apply to Imperial dimensions and currently only operate on MicroStation DGN drawings using a special font.

Set OS 41 Pos 4 = 1 for weights output in KGS format. Set OS 41 Pos 5 = 1 for component weights listed as total weights.






Set OS 41 Pos 4 = 1 for weights output in KGS format. Set OS 41 Pos 5 = 2 for component weights listed as individual weights.

This option switch controls the output of basic component weights. More extensive weight functionality, including pipe fill, weights of insulation, and center of gravity calculations, are controlled by Option Switch 82 (see "Option Switch 82: Center of Gravity/Weight Output" on page 138).

Set OS 41 Pos 6 & 7 = 0 or leave blank for imperial dimensions output format. Dimension output format changes from inches to feet at 24-inches. For example, 28" is output as 2' 4". This is the default setting






Set OS 41 Pos 6 & 7 = 12 for imperial dimension output format to change from inches to feet and inches at 12-inches.

Set OS 41 Pos 8 = 0 or blank for plotted bore information at branches and reducers.

Set OS 41 Pos 8 = 1 for bore information not plotted at branches and reducers.

See Also Option Switch 41: Bore/Dimension/Weight Control (on page 69)



Drawing Viewpoint (OS 42) Set OS 42 = 0 or OS 42 = 3 to output the North arrow as follows:

Set OS 42 = 1 to output the North arrow as follows:






Drawing Viewpoint (OS 42)

Pipe Wastage Factor - Areas 1 to 9 (OS 43 - 51) The ISOGEN pipe wastage facility allows extra tube material to provide for wastage during spool fabrication. When the facility is used, you can manually increase the pipe length entries on the material list.

1. The basic pipe wastage allowance is set by the user in the piping model on a plant area number basis. This value is expressed in terms of a percentage wastage factor, such as 10%, and is extracted and held at the pipe component level in the piping data file.

The basic pipe wastage allowance operates independently of any settings in option switches 43 - 51. For example. a nominal tube length entry of 1,000 mm that has a 10% wastage factor set in the piping model means the actual material list entry would be 1,100 (1,000 + 10%).

If the pipe wastage allowance value in the piping data file is set to zero, then option switches 43 - 51 will have no effect.

2. Any such basic pipe wastage factor set in the piping model may then be overridden and increased (never decreased) by the user with option switches 43 - 51. For example, if the pipe was in PlantArea 2 and the wastage allowance needed to be increased to 20%, then Option Switch 44 would be set to 2.

See Also Option Switch 43: Pipe Wastage Factor (Area 1) (on page 74) Option Switch 44: Pipe Wastage Factor (Area 2) (on page 75) Option Switch 45: Pipe Wastage Factor (Area 3) (on page 76) Option Switch 46: Pipe Wastage Factor (Area 4) (on page 77) Option Switch 47: Pipe Wastage Factor (Area 5) (on page 78) Option Switch 48: Pipe Wastage Factor (Area 6) (on page 79) Option Switch 49: Pipe Wastage Factor (Area 7) (on page 80) Option Switch 50: Pipe Wastage Factor (Area 8) (on page 81) Option Switch 51: Pipe Wastage Factor (Area 9) (on page 82)



Equipment Trim Drawings (OS 52) Equipment trim isometrics are special types of drawings where ISOGEN produces a document having a BOM, an outline frame and a large empty area.

In this example, the materials connected to each nozzle are grouped and listed separately, as shown below. This type of listing is produced by setting OS 52 Position 1 = 0.

The drawing (shown in green) is produced in a 2D drawing system, such as AutoCAD or MicroStation, and inserted into the empty area of the ISOGEN isometric.

See Also Option Switch 52: Equipment Trim Drawings (on page 83)



Weld Numbering (OS 53) Set OS 53 = 1 for small-sized weld numbers.

Set OS 53 = 2 for medium-sized weld numbers.

Set OS 53 = 3 for large-sized weld numbers.





Weld Numbering (OS 53)

Set OS 53 = 6 for medium-sized fabrication welds.

Set OS 53 = 8 for medium-sized erection welds.






Set OS 53 Pos 2 = 1 for user-defined weld summary box. You must also use a Weld Definition File (WDF) for this box to work correctly. For details on the WDF, see the separate welding switches.

There is an alternative weld summary box that does not require a WDF, but it is not user-defined. It uses a fixed layout and the content cannot be changed. Setting OS 53 Position 2 = 1 uses the alternative weld summary box.






Set OS 53 Pos 5 = Blank to use the same weld numbering sequence between fabrication and erection welds.

Set OS 53 Pos 5 = 1 to use separate weld numbering sequences between fabrication and erection welds.

Individual enclosures and weld number prefixes are recommended in this case.

See Also Option Switch 53: Weld Numbering (on page 85)



Weld Plotting (OS 54) Set OS 54 = 1 to suppress all welds.

Set OS 54 = 2 to only plot site welds.

Set OS 54 = 3 to only plot fabrication welds.

Set OS 54 = 0 to make all welds appear as erection welds.

Set OS 54 = 4 to make all welds appear as fabrication welds.

This option switch also changes the type of weld numbers generated.

See Also Option Switch 54: Weld Plotting (on page 88)

Instrument Identification (OS 59) Set OS 59 = 0 to output the instrument name on the material list.

The text in red indicates the instrument name in this illustration.

Set OS 59 = 1 to output the instrument item code on the material list.

The text in red indicates the instrument item code in this illustration.

This option switch only controls what parameter is output (instrument name or item code) on the material list or material control file. On the drawing, the instrument name is always displayed regardless of the option switch setting.

See Also Option Switch 59: Instrument Identification (on page 96)



Component Tagging (OS 60) Set OS 60 = 0 for no component tagging.

Set OS 60 = 1 for boxed in component tagging.

Set OS 60 = 2 for component tagging with no boxes.

See Also Option Switch 60: Component Tagging (on page 97)



Insulaton Indication (OS 61) Set OS 61 = 0 for insulation indication alongside pipe only.

Set OS 61 = 1 to suppress insulation indication.

Set OS 61 = 2 for insulation indication alongside pipe and components.

See Also Option Switch 61: Insulation Indication (on page 98)



Tracing Indication (OS 62) Set OS 62 = 0 for tracing indication alongside piping only.

Set OS 62 = 2 for tracing indication alongside piping and components.

Set OS 61 = 0 and OS 62 = 0 to trace and insulate piping.

See Also Option Switch 62: Tracing Indication (on page 99)



Printed Output - Page Length (OS 63) Set OS 63 = 0 for 55 lines of output.

Set OS 63 = 66 for 66 lines of output.

Set OS 64 = 1 for support name on the isometric with no box, and support name output on the material list.

Set OS 64 = 2 for boxed support name on the isometric, and item code output on the material list.

See Also Option Switch 64: Pipe Support Identification (on page 101)



Bolting Units (OS 65) Bolts on the isometric material list and in the material control file can be reported in any combination of diameter and length units.

For example:

5/8" Dia x 4" Long

5/8" Dia x 100mm Long

16mm Dia x 100mm Long

16mm DiaxX 4" Long

The purpose of this option switch is to enable the bolt diameter and length values held in the piping data file to be correctly interpreted by the software. Regardless of what units are being used, all bolt diameter and length values are stored in the piping data file as integer type numbers. For example, inch units are stored in 1/16's of an inch, while millimeter units are stored as millimeters.

Therefore, every unit is converted to either 1/16's of an inch or millimeters. For example:

5/8" diameter is stored as 10/16

4" long is stored as 64/16

16mm diameter is stored as 16

100mm long is stored as 100

The option switch setting must match the bolt unit values in the piping data file in order to produce correct results.

See Also Option Switch 65: Bolting Units (on page 103)



Coordinates - Supplementary (OS 66) Set OS 66 = 0 for only elevation changes to be displayed. North, South, East, and West coordinate changes are not output. This is the default setting.





Coordinates -- Supplementary (OS 66)

Set OS 66 = 1 for all supplementary coordinates and elevation to be output along witness lines instead of leader messages.






Set OS 66 = 221 to output supplementary elevations and coordinates at bends, elbows, and branch intersections in all cases were the elevation level North, South, East, or West coordinates have changed.






Set OS 66 = 330 or set OS 66 = 331 for a full set of all three coordinates output.

Set OS 66 Pos 4 = Blank to omit split point coordinates.






Set OS 66 Pos 4 = 1 to output split point coordinates.

See Also Option Switch 66: Coordinates (Supplementary) (on page 104)



Sloping Pipeline - 3D Skew Depiction (OS 67) Set OS 67 = 0 for a 3D box depiction.

Set OS 67 = 1 for a 2D triangle and fall indicator.

See Also Option Switch 67: Sloping Pipeline (3D Skew Depiction) (on page 107)



Sloping Pipeline - Vertical Branches (OS 68) Set OS 68 = 0 for a skewed short tee branch. This is the default setting.

Set OS 68 = 1 for a straight short tee branch.

See Also Option Switch 68: Sloping Pipeline (Vertical Branches) (on page 109)



Terminal Type Identification (OS 69) This option switch displays the isometric drawings directly to the monitor instead of sending them to a file and plotting them.

You cannot send isometric drawings directly to the monitor if you are using the PC version of ISOGEN or SPOOLGEN. All isometric output must first be output to a file.

See Also Option Switch 69: Terminal Type Identification (on page 110)



Skew Indication - Branches (OS 70) Set OS 70 = 0 to display a normal skew box with triangle depiction.

Set OS 70 to a user-defined value to display a skew box with a suppressed triangle. In the following example, OS 70 = 4 was used.

See Also Option Switch 70: Skew Indication (Branches) (on page 112)



Material Part Number - Enclosure Style (OS 73) Set OS 73 = 0 for a standard part number box with no special blank style enclosure box.

For square-ended Style 1 blank enclosure boxes with 12 blank character spaces, set OS 73 = 12.

The blank boxes are for manually added information.

The end type of a Style 1 enclosure box is controlled by Option Switch 73 Position 5.

For diamond-ended Style 2 enclosure box with 12 blank character spaces, set OS 73 = 1200.

The end type of a Style 2 enclosure box is controlled by Option Switch 76 (see "Option Switch 76: Material Part Number Enclosure Shape" on page 124).

See Also Option Switch 73: Material Part Number Enclosure Style (on page 116)



Material List Accumulation Control (OS 74) Set OS 74 = 0 for normal accumulation of erection and offshore materials. This is the default setting.

Set OS 74 = 3 for non-accumulation of fabrication materials (including pipe).

Non-accumulation means that each occurrence of an item results in a quantity of 1 off being listed. Each individual pipe length is listed separately.





Material List Accumulation Control (OS 74)

Set OS 74 = 13 for non-accumulation of erect materials. Gaskets and bolts are accumulated normally with this setting.

Set OS 74 = 11113 for non-accumulation of all erect materials. Gaskets and bolts are also non-accumulated with this setting.

Bolts are included as sets.

See Also Option Switch 74: Material List Accumulation Control (on page 118)



Weld Number - Enclosure/ Prefix (OS 75) Set OS 75 = 201 to display round-ended enclosures for erection welds (A) and diamond-ended enclosures for fabrication welds (B).

The following illustration shows the resulting output on the isometric drawing:

Fabrication and erection welds use their own weld numbering sequence.

Weld number prefixes are not shown.

Set OS 75 = 1211 to display round-ended enclosures for erection welds and diamond-ended enclosures for fabrication welds, all with weld number prefixes. The relationship between the switch settings and the isometric output are as follows:

A - Display erection weld prefix.

B - Output round-ended enclosures for erection welds.

C - Display fabrication weld prefix.

D - Output diamond-ended enclosures for fabrication welds.



The following illustration shows the resulting output on the isometric drawing (SH refers to fabrication welds, while ER refers to erection welds):

OS 75 controls only the weld number prefix option; it does not define the prefix character(s).

In the ISOGEN and SPOOLGEN systems, the prefix characters are defined using the -130, -131, -132, and -133 records.

In the IDFGEN system, the prefix characters are defined using the following pipe header attributes:

WELD-PREFIX-GENERAL

WELD-PREFIX-ERECTION

WELD-PREFIX-FABRICATION

WELD-PREFIX-OFFSHORE

See Also Option Switch 75: Weld Number (Enclosure Weld Number; Weld Number – Prefix) (on page 121)



Material Part Number Enclosure Shape (OS 76) Set OS 76 = 0 for rectangular enclosure. This is the default setting.

Set OS 76 = 1 for diamond-ended enclosures.





Material Part Number Enclosure Shape (OS 76)

Set OS 76 = 2 for round-ended enclosures.

Set OS 76 = 7 for no enclosure boxes.





Material Part Number Enclosure Shape (OS 76)

Set OS 76 = 8 so that no part numbers nor enclosure boxes are shown.

See Also Option Switch 76: Material Part Number Enclosure Shape (on page 124)

Option Switch 77: Weld Number Allocation at Slip-on Flanges and Reinforcement Pads (on page 126)



Dimensions - To Valve Centers (OS 80) Set OS 80 = 0 for ordinary dimensioning to the valve ends. This is the default setting.

Set OS 80 = 1000 for dimensioning to the valve center on socket weld valves and instruments.

This example is for a socket weld valve. The dimensioning method for it is controlled by Option Switch 80 Position 4.

Further control by bore for this function is available in OS 81 Position 1 (see "Option Switch 81: Dimensions (Branches)" on page 136).

See Also Option Switch 80: Dimensions (To Valve Centers) (on page 134)



Dimensions - Branches (OS 81)

OS 81 Positions 1-3: Extension of OS 80

Positions 1-3 of this option switch are not for branches; they are an extension of Option Switch 80 (see "Option Switch 80: Dimensions (To Valve Centers)" on page 134), whereby dimensioning to the centers of valves and instruments can also be done by bore range. Option Switch 80 controls dimensioning to the centers of valves and instruments by end type.

In the following example, OS 81 Pos 1-3 = 24 and OS 80 Pos 4 = 1, which gives dimensions to the socket weld valve and instrument centerline for all bores up to and including 1-1/2 inches.

In the next example, OS 81 Pos 1-3 = 24 and OS 80 Pos 4 = 1, which gives dimensions to valve ends for 2-inch bore. That is, the valve is outside the bore range set in OS 81, so it does not get center-dimensioned.






OS 81 Positions 4-6 and Positions 7-8: Branch Dimension Function

Branch dimensioning functions are controlled by Option Switch 81 Positions 4, 5 and 6 and Positions 7 and -8. In the following example, OS 81 Pos 4, 5, 6 = Blank and OS 81 Pos 7, 8 = Blank, which gives full branch dimensioning regardless of the branch bore and the number of components in the branch.

In the next example. OS 81 = 48 000, which suppresses branch dimensioning on branch bores of 3-inches or less regardless of the number of components in the branch.






The following example sets OS 81 = 2 048 000, which puts branch dimensioning back on again because the branch has more than two components.

See Also Option Switch 81: Dimensions (Branches) (on page 136)



Center of Gravity/Weight Output (OS 82) Option Switch 82 provides further weight functionality to that in Option Switch 41 Positions 4 and 5. The latter is for basic component weights only. Option Switch 82 provides controls for the following:

Full (wet) pipeline weight

Weight of insulation

Center of gravity of pipeline, empty or full, with or without insulation

OS 82 Pos 1 switches on the CoG / weights facility and controls whether the output values are per pipeline or per drawing. For weight outputs, set .

The weight outputs show the following values:

Dry weight (pipeline empty)

Wet weight (pipeline full)

Insulation weight

In the previous example, weights are per drawing (Pos 1 = 1) and are output in this style on the drawing frame using the ISOGEN TextPos facility.

The pipe empty weight is derived solely from the weight of components.

For center of gravity outputs, set .

The center of gravity outputs show the following values:

Dry (empty) center of gravity

Dry (empty) plus insulation center of gravity position

Wet (full) pipe plus insulation center of gravity position

See Also Option Switch 82: Center of Gravity/Weight Output (on page 138)



DXF File Units (OS 92) Drawing Underlay:

Detail Sketches:

Where used, the drawing underlay and detail sketches must be consistent in the units with which they are constructed. ISOGEN generates the resulting output drawing (as shown in the following example) in the same units.

Isometric Output Drawings:

See Also Option Switch 92: DXF File Units (on page 149)



Component Leg Length (OS 95) Set OS 95 = 0 for leg length of 9mm. This is the default setting.

Set OS 95 = 12 to use increased leg length of 12mm.

See Also Option Switch 95: Component Leg Length (on page 151)



Skew Depiction - Individual/Overall (OS 97) Set OS 97 = 0 for single overall box or triangle enclosure around the skew section. This is the default setting. The following example shows a triangle enclosure.

Set OS 97 = 1 for individual box or triangle enclosure around each skew section.

See Also Option Switch 97: Skew Depiction (Individual and Overall) (on page 154)



Skew Depiction - Style (OS 99) Set OS 99 = 0 for skew box depiction with normal dimensioning style. This is the default setting.

Set OS 99 = 1 for skew triangle depiction with normal dimensioning style.

Set OS 99 = 3 for skew triangle depiction with alternative dimensioning style.

3D skew sections normally follow the value in Position 1 that are set for 2D skews, unless the value is set in Pos 2.





Skew Depiction - Style (OS 99)

In the following 3D skew example, OS 99 Pos 2 = blank, that is, it is not set. Consequently, the skew type follows what is set in Position 1, in this case, value 3, which gives triangle depiction with alternative dimensioning style.

Changing the setting so that OS 99 Pos 2 = 1, results in the 3D skews shown in the box style.

See Also Option Switch 99: Skew Depiction (Style) (on page 156)



Skew Depiction - Dimension Line Standout (OS 100) This option switch is used to move the triangle dimension further out.

Set OS 100 = 0 for standard dimension distance plotted alongside the triangle line (A). This is the default setting. If you set OS 100 = 120, the result is an increased standout distance of 12mm (B).

See Also Option Switch 100: Skew Depiction (Line Standout Dimension (on page 159)



Skew Depiction - Triangle Hatching (OS 101) Option Switch 101 enables skew triangles to be optionally filled in with hatching lines. The various switch settings allow you to:

Vary the distance between the hatch lines.

Have full or partial hatching. With partial hatching only a section of the triangle is hatched.

Vary the amount of hatching when using partial hatching.

Set OS 101 = 1 to turn on triangle hatching. The result is full hatching with a hatch line pitch of 1mm. This is the default setting.

Set OS 101 = 40 to give full hatching with an increased hatch line pitch of 4mm.

Set OS 101 = 3540 to give partial hatching with a hatch line pitch of 4 mm and a maximum line length of 35mm.

See Also Option Switch 101: Skew Depiction (Triangle Hatching) (on page 160)



Skew Depiction - Hatching Clearance (OS 102) Option Switch 102 controls the size of the clearance gaps that occur in and around hatching. There are three of these gaps:

Local to the pipeline

Local to in-line components

Around dimensions and text that appear in the hatching region

Set OS 102 = 0 to define gaps at all three regions. This is the default setting.

Set OS 102 = 404040 to increase gaps at all three positions to 4mm.

See Also Option Switch 102: Skew Depiction (Hatching Clearance) (on page 161)



Pipeline Splitting - In Pipe (OS 108) Option Switch 108 controls what action ISOGEN must take when it encounters a situation where it wants to split the pipeline into two drawings (in tube) at the point shown in the following illustration:

See Also Option Switch 108: Pipeline Splitting (In Pipe) (on page 166)



Repeatability File Content (OS 109) The Repeatability, or Return, File System is used when it is necessary to pass ISOGEN-generated data back to the 3D design software.

Not all 3D design software supports this system.

Option Switch 109 also contains a non-repeatability function. Position 6 controls the action of component re-ordering in by-passes. This re-ordering function is performed by default when you set OS 109 Pos 6 = Blank.

To correctly generate spools in a by-pass, such as the one in the following illustration, ISOGEN requires that the closure point be at either one of the two locations (A).

However, the Intermediate Data File (IDF) extraction software of some 3D design products sets the closure point at location B.

Set OS 109 Pos 6 = 0 or OS 109 Pos 6 = Blank to cause ISOGEN to also set the by-pass closure point at the preferred location. If this setting proves problematic, set OS 109 Pos 6 = 1.

See Also Option Switch 109: Repeatability Content (on page 168)



Ghost Gaps (OS 110) Ghost gaps are created in the 3D design system and are used to link related, but unconnected, components such as:

One pipeline to another to form a system isometric

One part of a pipeline to another part of the same pipeline where the middle section may remain incomplete and unfinished.

The following example shows part of a system isometric that consists of two pipelines. Set OS 110 = 0 to give a standard-sized gap (A). Set OS 110 = 50 to increase the gap size (B).

Gaps may be dimensioned or un-dimensioned, which is controlled from within the 3D design system by defining the appropriate settings in the extracted piping data file. In the previous example, the gaps are un-dimensioned.

See Also Option Switch 110: Ghost Gaps (on page 170)



Nozzles (OS 111) Set OS 111 = 0 to suppress the plotting of nozzles. This is the default setting.

Set OS 111 = 0 to plot nozzles.

See Also Option Switch 111: Nozzles (Dotted) (on page 171)



Flow Arrows - Pipeline (OS 112)

Set OS 112 = 0 to give the following output:

Set OS 112 = 0 or OS 112 = 8 to give the following output:

Set OS 112 = 15 to give the following output:

See Also Option Switch 112: Flow Arrows (Pipeline) (on page 172)



Specification Break Indication (OS 114) Set OS 114 = 0 to output a single spec break indication box. This is the default setting.

The single spec break indication box is considered redundant and is not recommended. As shown in the previous example, it is unclear as to which side of the division line the spec break is referring.

Set OS 114 = 1 to output a two box indication. This is the recommended method since this style is more informative. In the following illustration, the spec for both sides of the division line is clearly indicated.

See Also Option Switch 114: Specification Break Indication (on page 174)



Tolerance - Offset Angle (OS 115) Option Switch 115 enables you to prevent the generation of unwanted skews. The piping data file extraction utility of some 3D design systems can contain small dimension inaccuracies that lead to small movements at some pipe ends. When ISOGEN detects these small movements, it generates a skew section.

Example 1: OS 115 = 0

In the following illustration, a 3 mm movement in the N/S plane results in a skew angle of 0.08-degrees (A).


In the following illustration, setting a 0.25-degree cut-off angle suppresses the generation of the unwanted skew.

Option Switch 116 uses a dimensional tolerance to control skew generation. Of the two option switches, using Option Switch 116 is the preferred method; however, if both are set, Option Switch 115 takes precedence.

See Also Option Switch 115: Tolerance (Angle Offset) (on page 175) Option Switch 116: Tolerance (Dimension Offset) (on page 176) Tolerance - Dimension Offset (OS 116) (on page 338)



Tolerance - Dimension Offset (OS 116) Option Switch 116 also enables the prevention of unwanted skews, but uses a dimension tolerance rather than an angle tolerance.


In the following illustration, a 1mm movement in the N/S plane causes a skew to be generated (A).

Example 2: OS 116 = 250

In the following illustration, setting a 2mm cut-off value suppresses the generation of the unwanted skew.

Option Switch 115 uses an angular tolerance to control skew generation. Of the two option switches, using Option Switch 116 is the preferred method; however, if both are set, Option Switch 115 takes precedence.

See also Option Switch 115: Tolerance (Angle Offset) (on page 175) Option Switch 116: Tolerance (Dimension Offset) (on page 176) Tolerance - Offset Angle (OS 115) (on page 337)



Dimensions - Overall (OS 118) Set OS 118 = 1 to output overall dimensions that extend across branches.

Set OS 118 = 2 to output overall dimensions that stop at branches.





Dimensions – Overall (OS 118)

Set OS 118 = 3 to output overall dimensions to valve centers and across branches.

Set OS 118 = 4 to output overall dimensions to valve centers but stopping at branches.





Dimensions – Overall (OS 118)

When you set OS 118 = 344, the 34 in Pos 3 and 4 causes the standout distance for the overall dimensions to be moved out from the standard distance to 34mm. This setting, as shown in the following example, causes the standard dimension layer to move to the inner position (A).

If you define values in OS 118 Pos 2 and 3, you must also define a value for OS 8 to control the normal dimension standout distance and keep it in the standard position.

See also Option Switch 118: Dimensions (Overall) (on page 178)



Dimensions/Elevation - Vertical (OS 119) Set OS 119 = 0 to plot normal vertical pipe dimensions and elevations at intersection points when the level changes. This is the default setting.

Set OS 119 = 1 to suppress vertical dimensions and replace them with elevation messages.





Dimensions/Elevation –Vertical (OS 119)

Set OS 119 = 2 to output vertical dimensions and elevations at all normal dimensioning positions.

See Also Option Switch 119: Dimensions/Elevations (Vertical) (on page 179)



Tapping - Branch Scale (OS 120)/Branch Dimensions (OS 121)/Branch Coordinates (OS 122)

Set OS 120 = 0 to output a full-size branch.

Set OS 121 = 0 to turn on branch dimension.

Set OS 122 = 0 to suppress output of tapping point coordinates.

Set OS 120 = 60 to output reduced branch scaling.

Set OS 121 = 1 to turn off branch dimensions.

Set OS 121 = 1 to plot tapping coordinates.

See Also Option Switch 120: Tapping (Branch Scale) (on page 181) Option Switch 121: Tapping (Branch Dimensions) (on page 183) Option Switch 122: Tapping (Branch Coordinates) (on page 185)



Instrument ID Enclosure (OS 123) Set OS 123 = 0 to suppress output of a balloon enclosure around the instrument name. This is the default setting.

Set OS 123 = 5 to plot the instrument name inside a five-character sized balloon.

Set OS 123 = 4 to plot the instrument name over two lines. In the following example, the instrument name is inside a four-character balloon.





Instrument ID Enclosures (OS 123)

Set OS 123 = 100 to plot the instrument name inside a diamond-ended box enclosure.

OS 123 Position 3 controls the following alternative enclosure box shapes:

Position 3 Setting Enclosure Shape

1

2

3

4

5

See Also Option Switch 123: Instrument ID Enclosure (on page 186)



Flange Rotation Angles (OS 124) Set OS 124 = 0 to suppress the indication of flange rotation angles. This is the default setting.

Set OS 124 = 1 to indicate flange rotation angles.





Flange Rotation Angles (OS 124)

Set OS 124 = 11 to indicate flange rotation angles in a diamond-ended box.

OS 124 Position 2 also controls the following box shapes:

Position 2 Setting
