Simon Moreau has shared a nice addin for Navisworks that allows the automatic grouping of clashes. From his blog:
“This plug-in enables a lot of possibilities for sorting clash detection results in a meaningful report, and will become a full-time member of my coordination toolbox.

To install this plug-in, you can copy-paste the ClashDetective.ADSK.dll file available here in a new ClashDetective.ADSK folder in C:Program FilesAutodeskNavisworks Manage 2016Plugins. You can also see my edited version of the example code here.”

Here is what the installation folder looks like:

And the addin ribbon in Navisworks Manage 2016:

You can also download the Navisworks SDK from here:

Simon Moreau has put together and shared some API code that allows him to track the time taken to open and work with Revit models. I can see this would be a good way to identify “problem” Revit central files that were taking a long time for users to sync. Once the problem models are identified, they could be fixed, and people might be happy 🙂

From bim42:
It is now possible to quickly create very precise graph displaying opening time of different model, compare them and show their evolution along time
