The main difference between images is between bit mapped and vector based, Vector is always used for Cad or higher end graphics drawing because the vector is based on mathematical equation not independant pixel.
This is why you can enlarge a vector image without losing resolution like a bit map does, they both of course display as pixels on the PC but are completely different in structure.
I have had fairly good success transfering Corel DXF to Autocad except for some text styles for some reason.
