Problem

I get a Crash when trying to export 3D model to shapefile using the Asset manager

Possible solution

There are cases when clearing the user preferences will solve this issue.

The prefs and temp data contains coded files which can become corrupt and lead to crashing at startup as well as operational issues with commands not performing correctly, buttons not working, etc. Check here for a video on Deleting User Prefs and Temp folders 

The prefs folder and temp files can be deleted from the following locations: 

C:\Users\USER.NAME\AppData\Local\Bentley\OpenRoadsDesigner\10.0.0\prefs

C:\Users\USER.NAME\AppData\Local\Temp\Bentley\OpenRoadsDesigner\10.0.0
NOTE: If you do not see the AppData folder, it is a hidden item and would need to be enabled.  To do this in the Windows explorer, go to View and toggle on the option for Hidden Items
