Products and versions covered

Users reported that there is a performance issue with Navisworks, it slows down when working with large files (500 MB or larger).

This problem can be caused by too many overrides to transformations or appearance.

To overcome this slowness, try the following:

Make sure that Navisworks Exporter is installed.
Make sure that all Object Enablers are installed.
Decrease the size of the file.
Remove any unsupported content.
Log out of A 360/BIM 360.
If the file in question has so many NWCs & NWDs appended within, then try splitting the file into 2 or 3 files, rather than nesting all the data within a single file.
Check the options file:
- Export the Options file from the system performance is good.
- Import the Options file to the system where performance is low.
Make sure Navisworks is installed with the latest updates.
Try to use latest version of Navisworks.
