What does the error message say? Do you know what program the DXF file came from? If you can get a DWG (R2000 or R14 will work) instead, that would probably be preferable.
When I try to open the DXF file DataCad reads (error in file). I am using
DataCad 11.05.02. A program I have never heard of (Tunch) I suspect it
is one of those $39.99 Programs.
