Unfortunately we have received some reports of a problem with the Trimble Connect for Windows release. In some cases, the application may crash when accessing the Point Clouds feature:




The issue can be fixed by uninstalling the Connect for Windows application and then re-installing. Steps to follow are:

  1. Open Windows Settings --> Apps & features --> Search for Trimble Connect --> Click Uninstall
  2. Run the installer package again (TrimbleConnectSetup-


We are sorry for the inconvenience.


Update on February 20, 2020:


We have completed the issue investigation. The conclusions are:


  • The root cause of the issue was that the 1.9.1 version installer placed some code libraries in a wrong place
  • The crash happens only if the application is updated from 1.9.1 to 1.9.2 without uninstalling 1.9.1 first
  • When the update is done from 1.9 directly to 1.9.2, then there is no crash
  • If a user is experiencing the crash, the fix is to first uninstall the application, then reinstall 1.9.2 (see steps above)
  • Since there is no problem detected in the 1.9.2 version, we are not planning to release a new patch version in the short term

The Trimble Connect 3D Viewer version 1.0.45 release introduced the Clash Sets feature. With the new feature you can both create new clash sets and view existing clash sets that were created with the Connect for Windows application.



Creating a New Clash Set

To create a new clash set:


  1. Click the Add clash set button in the top of the panel
  2. Give a name for the clash set, the tolerance value and select models that are to checked for clashes: 


Note: The models must be first loaded to the viewer from the Models panel before they can be included in the clash set.

Viewing Clash Sets


  1. Click the name of a clash set in the list
  2. Select a clash. The clash details panel will open which lists the clashing objects and possible actions. For example, you can quickly create a new ToDo where the clash is added as attachment. 


Important Clashes


The important clashes feature helps to identify the most important clashes. You can narrow down the list of found clashes by clicking the flag icon in the important column: this action marks the clash as irrelevant and changes the filter so that only important clashes are visible in the list. You can then quickly create a ToDo with all the important clashes as attachments.



Note: The important flag is temporary only. To save and share the important clashes, make sure to add them to a ToDo.


Upcoming Improvements


Currently we are developing a renewed version of the cloud based clash detection computation engine which powers both the Connect 3D Viewer and the Connect for Windows application. The new engine will improve the performance of the clash analysis computation so that the processing will be completed and results displayed in shorter time. There will be a separate announcement before the new computation engine is introduced.
