A Maxscript I wrote to aid in the import of DWG files that have been exported from Revit. This script imports the DWG file and then exports to an OBJ file as an intermediary to clean up the layers and geometry. The OBJ file is then re-imported into 3DS Max where it is further processed and cleaned up. There are options to show the Import/Export dialogs for manual adjustment of settings, but the script loads optimized settings automatically. There is also an option to automatically save out a Max file when complete. Additional files will be created in the same folder as the original DWG file; an OBJ file (Intermediary) and a MAX file (If this option is selected).
