When exporting to fbx straight from revit, points seem to get welded together. This is very inconvenient for example when the glass gets fused to the frame of a window or the door get fused to the jamb. The only way i can see to work around this is to edit the original component and split it into sub-components which will export as an attribute in the fbx but this would be extremely tedious and unscalable. Thankyou for your time.
