The big problem also when import DXF format file from Revit to MAX ! and when linked revit file in 3d max directly talk a lot of time ...must be autodesk found profissional solution !!
*3D max dont creat profissional sectin ..
*Revit can't create realistic animation render
* From revit to max fbx , dxf or like revit directly i feel like tray but Horse above car and I pull them !!
