Assembling a truss yourself

In this exercise the following items are handled :

- drawing a truss based on a model line
- connecting a truss to columns
- copying a truss together with all it's component connections

- Open the drawing Assembling a truss yourself.dwg

- Click on the icon Truss

- Double-click on Truss oblique

- Select the model line that is located between the intersections A11 and C11

- Then press <Enter> to end the command

This is the simplest method for drawing a truss.

However the truss has no knowledge of the columns and therefore it is not connected to them.

- Press the  button to close the truss parameters window

We will now connect the truss to the columns.

- Click on the icon Truss haunch connection

- Select the column on intersection A11

- Select the bottom chord

- Select the top chord

- Double-click the connection Truss Endplate

- Select the column on intersection B11

- Select the bottom chord

- Select the top chord

- Then press <Enter> to end the command

- Activate the Bolts tab in the parameters window of the endplate

- Modify the horizontal number of bolts 4 times to 1

- Press the  button to close the endplate connection window

The first and last struts of the truss are colliding with the endplate. This can be solved by shortening the length of the array of struts, or by cutting the first and last struts.

The first and last struts are colliding with the column. We will fix this by drawing two cuts.

- Click on the icon Add cut to macro

- Make sure that the Cut perpendicular setting is set to Not Perpendicular

- Then press to close the New cut window.

- Select the colliding strut on intersection A11

- Select the endplate of the column on intersection A11

- Click again on the icon Snede als macro tekenen

- Press in het New cut window.

- Select the colliding strut on intersection C11

- Select the endplate of the column on intersection  C11

- Click on Clash Check to check the entire drawing for collisions.

One bolt is yellow because it collides with the strut. We can solve this by changing the start and end offset of the first and last struts.

- Click on the icon Review macro

- Select the biggest macro sphere of the truss

- Then press <Enter> to end the selection

- Modify the start offset of the array to -50

- Modify the end offset of the array to -50

- Then press to close this window

The bolt is not yellow any more because it can be bolted now.
