I am able to get my Rhino model’s preview into revit by using RiR and the toggle preview button but when I put it into sheet it does not get printed, i can see the model in the views but when converting to pdf it vanishes.
I’d recommend you categorize your post so it is more likely to be seen by someone that can help.
Cheers
This is moreof a revit problem. You should check your print settings. It depends what your import is defined as, your VG settings, filters and more. Try printing in another way for a quick solution. Give diroots prosheets a try.
