Define Clash Tests


Instead of defining Autodesk® Navisworks® clash tests manually, one by one, this app automatically defines Navisworks clash tests from a Clash Matrix file.

A clash Matrix Excel file should be a part of your company's standards and should be utilized for your projects.

If two test names in the Excel file match the defined Navisworks search set names, it creates a clash test for you. You can define the clash tolerance by editing the value between a column and a row in the Excel template file provided with the app.


Note: This app uses a custom installer (and not the standard App Store installer).

  • Double Set Clash
    Kryzttel Millan | April 13, 2022 Verified Download (What's this?)

    Is that possible to make a test with two or more sets vs only one?

    something like:

    Structural Framing & Structural Columns vs Architectural Walls

    Virtual Projects (Publisher) | May 26, 2022

    Thanks for your interest in our App. Not by default, this can be achieved if you create a new single searchset that can select both the framings and the columns.

    By this way, I want to ask your help making a refund of the product “Define Clash Tests” due to a bad choice in my account.

    After refund I wish to buy again with the correct account.
