Other Graphics may be submitted in *.TIF, *.GIF, *.JPG, *.CALS, *.PDF or *.BMP file format only. This option is intended for photos, conceptual sketches, etc., and not as an indication that raster file drawings will be accepted in lieu of Autodesk Architectural Desktop files. When a hard copy drawing in the drawing set includes photographs or other images the electronic file submission shall include a corresponding Autodesk Architectural Desktop *.DWG sheet file containing these raster images as xrefs or embedded files.
