CADintosh questions and answers (FAQ)
1. DXF files open as empty drawings
This error occurs if a DXF file from Autocad 2000 (or later) was saved as DXF 2000. This is because DXF 2000 uses special undocumented extensions. The usual solution (industry accepted solution) is to save the files as a DXF file in version 14 and then the files will open without a problem.
