I have already seen this and did not solve my problem:
http://forums.autodesk.com/t5/Autodesk-Navisworks/How-to-transfer-color-of-pipes-from-Revit-MEP-to-N...
When I try doing the above, it wants me to select a "material"... I do not need to set "materials" as I am not using it for render.. I just need to set the COLOR. Setting the COLOR alone is not an option that it gives me.
I want my model to appear in Navisworks with the same colors as defined in the "Lines Color" box, under "object styles" in the "vg" menu.
You would think this would be something easy just like how .dwg files bring in their own color. I just want the same colors as the MEP guys are seeing.
I have also tried in "navisworks settings" checking the "convert element properties" box, but that does not help with the color.
