Why are the colors not the same as in other BIM applications?
When generating issues from Navisworks, any override color information is stored in the issue in BIMcollab Nexus by default.
However, most BIM applications such as Archicad, Revit and Tekla do not support the use of these override colors. This means you might find that components in the viewpoint are displayed in their original color when opened in these applications.
Override colors can be seen when the issue is opened in other viewers/checkers such as BIMcollab Zoom.
