Some CAD programs offer the possibility of exporting CAD drawings as a plain images. Commonly exported as JPG, TIF or PNG. But since images can be easily converted between each other, any image works more or less. This will create a static image even from a 3D model and these files will no longer be useable as CAD files.

The table with program actions contains information about what each program is capable of doing with their files. This may be a good pointer for further searches for certain file conversions and help you find the converter you are looking for if our search result is insufficient for you. However, it is far from perfect and may sometimes show results which are not really usable because of the nature of the software handles the files. So a conversion that appears as possible, just because of matched actions, may in fact not be possible.
