Hello,
In 2018 you introduced the Navisworks underlay in Revit. Thank You. Linking these in provides a new Visual Style display. It mirrors what's seen in Navisworks. Due to its display style it displays much faster than Revit geometries. This is consistent with Navisworks.
Please create a Navisworks View Style for use in Revit. It would allow for easy geometry viewing.
Thank you for your consideration.
