We get mesh models from point clouds and drones photogrammetery. They work pretty well in any modeler EXCEPT Revit. Meshlab is superior to Revit and its free. Its been nearly 20 years!!! Please recognize we need to import meshes and make Revit more useable. Allow for importing .ply, .obj, .max - among other file types.
DXF is awful - it is huge and takes FOREVER to load.
None of the current import options bring in texture data.
