I'm in a project that requires exporting many sequential images with the rather simple rendering format presented below - just the linework and shadows. However, that seems to offer REVIT just enough complication that it's giving strange graphic artifacts when exporting the images to any format - TIFF, JPG, PNG, etc.
Zoomed right in everything is normal. But I need to capture wide 3D views, and at that point the joists underneath bleed through, ruining an otherwise clean image capture (see left image below). Besides playing with the REVIT's limited graphical options, I've also modified the model (a copy for rendering purposes) with thicker flooring and offset beams underneath to limit any risk of coincident planes interfering, however... the problems persist...
Any help or insight would be appreciated. Thanks.
