Collision checks can help track down overlapping duplicate members, members with no connections, problem connections and general collision situations.
The program performs various checks:
- Bolts are checked, including the creation distance at the head and nut and can be reversed in direction.
- Bolt patterns are checked against each other with verification for bolting tool spacing.
- Holes and exact beam cross sections (including root radii) are checked.
- Identical overlapping elements (beams/plates copied on top of themselves) and incorrectly modified elements are recognized.
Advance Steel provides a set of tools for finding collisions.

The Clash Check Tool
This tool checks for collisions in beams, plates, and bolts for an entire model or a selection set.
Access the command
In the Extended Modeling tab 
Checking panel, click
(Clash Check).
Command line: _AstM5CheckCollision
Collision Solid
The clash volume is displayed in red in the model. You should be able to see what is wrong and make the necessary corrections in the model.
Note: Correcting one clash may fix several other clashes. Collision solids are not created directly since there can be many. You can display the collision solid of a selected collision.
Workflow
- Check the model for collisions.
- Keep the list of collisions displayed.
- Display the collision solids one by one.
- Fix each found collision.
- Check the model for collisions.
Tip: Run the clash check after every one or two corrected collisions.
