Help Needed with Clash Detection Issue in Navisworks

[amascitelli]

Hello,

I am facing some difficulties while performing clash detection in this model. I am new to using Navisworks, so the issue might be something obvious that I am not noticing.

I loaded the NWC file of a building, and when running the clash detection, the software did not find any clashes. This result seemed unlikely, so I created a wall deliberately intersecting doors, windows, and railings as a test to see if any clashes would appear. However, after running the test, no clashes were detected.

Below, I have included some screenshots illustrating the workflow I followed:

1- Creation of a wall intentionally intersecting other elements.

2- Creation of group sets for different categories: A.20 Floors, A.30 Walls, A.50 Doors, A.60 Windows, and A.110 Railings.

3- Selection of elements to be checked for clashes.

I would greatly appreciate any guidance or suggestions from the community on what might be causing this issue or how to troubleshoot it effectively.

Thank you in advance for your help!

Use the Find Objects option and create a Search Statement. Use that to create Search Sets to find your objects. Then make rules using those Search Sets to in your clash detective.

Hello hmunsell,

Thank you for your response.

I had already created the search statement using "Find Objects," but it still wasn’t working. However, today I finally figured out the issue—turns out it was a classic beginner’s mistake. In the Clash Detection menu, under the Rules tab, I had selected the option to ignore elements from the same file.
