Group Clashes

A Navisworks Manage plugin for rule-based clash results grouping.

Getting Started

This plugin will help you to group clash result in a given Navisworks clash test. For now, you can group clashes by:

  • Nearest level
  • Nearest grid intersection
  • Element belonging to a model
  • Status, approval or assignment

Open the Group Clashes window by clicking on the Group Clashes button Select a clash test. The two selections involved in the clash test are displayed below. Select one or two clash rule. Since Navisworks Manage does not support subgroup for clashes, the group name will include the result of the two rules. Click on Group. For a full description of each grouping rule, visit


This application is devellop with Visual Studio 2015. To run this plugin, you will need Navisworks Manage 2015, 2016 or 2017. Just compile the solution and paste the resulting dll in the Navisworks Manage Plugin folder. Before modifying anything, I advise you to check the Navisworks Manage SDK on the Autodesk Developer Network.
