7.2 Title Blocks
REV.: 1 PAGE 6 OF 19
All drawings must utilize GASCO Title Blocks/Drawing Borders. Title Blocks/Drawing Borders have been prepared for each drawing size and are approved for PROJECT use.
Each drawing will have its own specific title. Titles must be self explanatory and concise. Project deviations should be avoided unless otherwise necessary.
The title of a drawing consists of three lines:
First line – Drawing Type;
Second line – Facility Description;
Third line – Area / Unit Description.
When completing the Title Block area for DRAWN BY, CHECKED BY, APPROVED BY, the individual’s first (and second) initial shall be entered.
All dates within the Title Block shall conform to the following convention:
DD-MM-YY
Dashes only are to be used to separate the year, month and day. Slashes (/), periods (.) or spaces shall not be used. The scale indicator of the drawing title block will be noted with the drawings scale.
For schematics or diagrams, the space shall state NONE. For drawings containing more than one scale, the space shall state AS NOTED. For all other scaled drawings the actual drawing scale shall be indicated in the space.
7.3 Drawing Scales
Please refer to the SCALING CHART below for Border Scale Factor for different drawing scales.
I
The scale shall be stated on all drawings;
A scale bar shall be shown on scale drawings, located above the title block area.
Where more than one scale is used on the same drawing, the scales shall be indicated against the view to which they apply, and the words ‘AS SHOWN’ shall appear in the title block;
Drawing not to scale shall be indicated thus: - N.T.S. in the title block;
All Installation and Plant Layouts shall be drawn to scale;

Drawing text is to remain consistent across all drawing in all disciplines. Without exception, Romans, is the font to be used on all drawings. Text sizes to be utilized are limited to the following:
Text on drawings must be legible if the size of the final hard copy print. Since many clients require reduced sets of drawings, the text size must allow for this.

In case where 0.8 width text will not fit, changing the text width is allowable, within certain limitations. Always consult your CAD Lead before changing text, to ensure consistency on a PROJECT, and at no time use a text width narrower than 0.75. Text ustification is limited to using only “Middle Left”,” Middle Center” and “Middle Right”.
The following are the special characters that are used regularly:

For Revision Numbering refer to “Numbering Procedure”, 5275-PP-581-01-002.
9.2 Revision Cloud
Revision tracking is an integral part of drawings’ life.The revision part of the drawing need to be “Clouded” and to be indicated with the revision triangle with revision number inside. This triangle is to be place at right hand side of the clouded portion.
All revisions must be clouded on the drawing and should have a revision triangle position next to the cloud;
Revision layers provide a history of drawing modification.
The drawing must be saved with all revision layers turn OFF.
9.3 Drawing Sheet Number
All drawing shall have a two-digit sheet number or otherwise specified.
Where only one sheet exists the sheet number shall be 01, where more than one sheet exists the sheets shall be numbered from 01/XX to XX accordingly
9.4 Hatching and Patterning
Patterning is the repeated placement of a hatch line or cell through a closed area at a specified interval (spacing), scale, and angle. You can place patterns on designated Layer.

10.1 Units Definition
REV.: 1 PAGE 11 OF 19
Units are a means of relating the system's internal measurement of units of resolution (UOR) to measurable units (meters, centimeters, etc.) to meet the needs of the design file;
Units are the coordinate units corresponding to the position and definition of a point in the file;
The Unit dictates the degree of accuracy for placement of elements in a drawing and determines the scale relationship of elements in the file.

11.0 LIMITS
12.0 GRIDS
Limits are initially set-up to 1200 X 900 units;
REV.: 1 PAGE 12 OF 19
Limits can fit for A4 to A1 size-drawing sheets.
A grid display can be assigned to working units to be used as a design aid. Grid unit is the value for the distance between the grid dots on the screen.
Grid is ON to give reference of drawing limits;
The value of GRID = 6 relates to 10mm = 1cm;
Dot to dot relates to one centimeter.

13.0 DIMENSIONING
Dimension lines shall be drawn in such a manner that they cannot be confused with other subjects;
Points to which the dimension lines relate shall be clearly indicated;
Dimensions that are not to scale shall be noted as “N.T.S.”;
Drafting lines should not cross dimension figure;
Dimension figures shall be written immediately above wherever possible;
Dimension variable controlling the overall size is DIMSCALE and is set to 1;

16.0 LAYER STRUCTURE
The design area of a CADD design file is composed of layers. These layers are used to separate equipment, types of lines and other drawing details to enable CADD to be a more productive tool. A layer structure table is given below for each type of drawing. However, the user may define additional layers and submit them for approval and addition to layer table.
Layer structures for CADD files must conform to the tables provided in Appendix -“A”.

17.0 DO’S AND DON’TS
REV.: 1 PAGE 19 OF 19
To ensure maximum productivity from the GASCO CADD systems, the following CADD drafting parameters must be followed:
Do not change the working units;
Do not change Approved title Blocks;
Do not change or explode standard symbol;
At the time of e-submittal, all drawings need to be copied & binding in the submittal folders;
Key Plan shall be placed above the revision description area;
Reference Drawings listed in space between notes and title block;
Draw according to specified layers;
Symbol for North and Wind direction once fixed hence shall be used in all drawings.
Generally CAD data shall be drawn full size and correctly positioned using plant
coordinates. Drawing scales will be achieved at the time of printing. E.g. Scale 1:500 2D CAD Drawing. Draw full size. Insert border as reference file, scaled up by a factor of 500. Plot file by placing a fence around border and plotting it.
Client or 3rd party drawings that used as background should be merged/ bounded into layers.
I
18.0 ELECTRONIC FILE SUBMITTAL
All electronic files of approved CADD engineering drawings must be submitted to GASCO as per PROJECT Procedures/Requirements.
All electronic files of approved CADD engineering drawings must be submitted to GASCO along with hard copy plots for archiving;
The electronic files must be submitted to COMPANY in the following;
All X-Ref’s should be binding (merged) into the drawings;
