I. Truss creating using earlier created sketch
We start this tutorial opening already created sketch file provided by this tutorial. SolidWorks allows users to create their own sketches of trusses. In this step we will create truss members by selecting Sketch Segments. New member will be placed new member will be placed along the whole segment as it is drawn.
1. Open file BW_Manual_2.sldprt with already existing truss sketch.
Fig. 1 Truss sketch
2. Click Member button (BuiltWorks toolbar) and click on Member Group button.

II. Truss members editing
In this step we will edit bottom chord and grid members of the truss by modifying their orientation in Member Orientation field. Bottom chord will be prolonged changing its Start Offset in Z direction, and extreme right and left members of truss grid will be Asymmetrically Offset in Y direction.
1. Left click on truss top and bottom chords group feature in FeatureManager tree and select Edit
Feature.
Fig. 6 Editing truss bottom chord feature
2. In Member Group dialog box Method of creation field select Beam2 as a truss bottom chord. In
Member Orientation field enter 300 mm as Start Offset in Z Direction.

4. Left click on truss grid member group feature in FeatureManager tree and select Edit Feature.
Fig. 9 Editing extreme left truss grid member feature
5. In Member group dialog box Member of creation field select Beam1 as extreme left truss grid
member. In Member Orientation field select Asymmetric and enter 240 mm as Offset of Profile in
Y Direction.

7. Repeat the same action for extreme right truss grid member.


III. Detailing Connection – Trim
In this chapter we will perform the detailing of Connections by trimming intersecting members.
1. Click Trim button (BuiltWorks toolbar).
Fig. 13 Creating a Connection
2. In Connection dialog box Members of connection field select truss bottom chord member in
graphic view.

10
3. Then select truss grid member and as Type of Cutting select By plane.
Fig. 15 Selecting of truss grid member
4. Then select next truss grid member and as Type of Cutting select By plane. Uncheck the trimming
option, which indicates that selected Truss Grid member (dark blue) is going to be trimmed to
another member of the Truss Grid (light blue) by Normal.

5. Click the OK button and cutting of truss grid members will be done.
Fig. 17 Creating a Connection – Final result

IV. Copying a Connection
BuiltWorks provides Copy Connection functionality, which benefits to saving the time for connection detailing by copying the detailing rules from one connection to other places, where it can be applicable. In this chapter we will copy trimming options for Truss bottom chord and Truss grid connection, which was created in previous chapter, to all remaining connections of the structure, where such Chord Grid connection is applicable. Before starting to Copy Connections, we need to highlight the existing connections in the model – connections are marked with functional Square Dot.
1. Click Show Connections button (BuiltWorks toolbar).
Fig. 18 Showing existing connections
2. Left click on blue dot in graphic view. Select Copy Connection button.
Fig. 19 Copy connection

3. Connection preview form window will be opened. Truss chord member colored as red. Select truss
top chord member in the model graphic view.
Fig. 20 Selecting of truss top chord member
4. Select truss grid member.
Fig. 21 Selecting of truss grid member
5. As truss top connection include only two members, for request to select next member click Skip.
Connection for selected members will be created and all members will be cut by copying
connection rule.

Fig. 22 Skipping of truss grid member
6. Repeat all actions for all truss connections and close copying connection preview window.
7. Hide blue dots representing created connections – push Hide Connections button.
Fig. 23 Copying a Connection Final result
Note: You may want to zoom and rotate graphic model in preview window to understand better
what is highlighted in red blinking color, so that the appropriate member in model could be
selected. You can also zoom and rotate your model in graphic view before selecting needed
member. Note also, that connecting members in the model can come to each other in different
angles (from different side) than in the preview window – it is normal, because Copy Connection
function does not copy geometry, but rather applies a set of engineering rules, stored in the
connection which is being copied.

V. Creating End Plates
In this chapter we will perform another Connection detailing function – create the End Plates for the members (truss top and bottom chords End Plates). Note, that creating the End Plate also creates the connection – the rule of creating End Plate with all parameters can be copied to another place equally as copying the connection with trimming rules. Connection can have a combined set of rules (some members trimmed, some have end plates added) and all these rules will be applied in another place where connection is copied.
1. For End Plate creating click End Plate button (BuiltWorks toolbar).
Fig. 24 End Plate
2. Select top chord of truss.
3. In End Plate dialog box Parameters field enter: Plate thickness 20 mm;
The profile type of the end plate – Rectangular; Plate Dimensions: Plate length – 280 mm, Plate
width – 220 mm.
Parameter 1 means, that member with end plate will be shortened on plate thickness. Enter Offset
of Profile in Y Direction – 30 mm.

4. Click the OK button and end plate will be created.
5. Repeat the same actions for end plate creation for another truss top chord member side.
6. For creating bottom truss chord end plates select bottom chord member. In End Plate dialog box
enter Plate thickness – 5 mm, The profile type of the end plate – Quadratical, Plate dimension –

VI. Assigning of material
In this chapter we will assign the materials to all members of the truss structure. Note, that if all the members of the structure are from the same material it is useful to assign the material using Solidworks Feature Manager. The same material will be assigned to all the members at once.
1. In SolidWorks FeatureManager design tree right click Material > Edit Material.
Fig. 28 Editing Material
2. Select Plain Carbon Steel material in the opened window and then click Apply and Close buttons.

VII. Generating a Drawing
In this final chapter of the tutorial we will learn how to automate the preparation of Drawings of the designed structure and insert the Bill of Materials (BOM). Drawings and BOMs are used later in manufacturing and erection of the structure. BOM for BuiltWorks model is created basing on cut list properties of both – SolidWorks documents as well as BuiltWorks custom properties.
1. To generate drawings for members select Drawing Generator button (BuiltWorks toolbar).
