CompuServe Thread

I am currently in the process of writing a DXF file converter. The converter is converting the DXF input to a proprietary file format. I have run into some problems. I am not precisely clear on how ellipitical shapes are handled by the DXF file format. My only significant source of information on the DXF format is a file which I downloaded from Compuserve. I have been producing DXF files with CorelDRAW! and it writes out ellipses as a CIRCLE entity with a value for the x-radius and y-radius. The format is as follows: 10, 20, ( centre), 41, ( xradius) 42 (yradius) Is this the correct way to handle ellipses? Any help in confirming what the format is would be most appreciated. One last question: is there a more detailed source of information on the DXF file format? This is not my account; it is my boss's ( just for clarity) Manjit Bedi
