   • C:\ProgramData\Autodesk\ApplicationPlugins\CreateClashTests.bundle\Contents\[Version]\Navisworks Clash Matrix\02. Clash Detection Matrix-S2-P02.xlsx
2. Make sure the Search set names in Navisworks match the Test Names in the Excel file and that the connecting cell has “Test Name” written in it
3. The tolerance is written in the intersecting cell between two search set names in the Excel file
4. Define the clash test type in the tolerance cell, Nothing = Hard, H = Hard, HC = Hard (Conservative), C = Clearance, and D = Duplicates
5. Run the Add-In
6. Browse for the Excel or CSV Clashes File, choose your settings, press “Start” 

In case you are using version 2018, you may face an authentication error, please try to run the Add-In first using any higher version of Navisworks.

You need to sign in with an A360 account (from the information center) the first time you run the Add-In to make sure you are allowed to use it.
