Every time I want to make a draft of a few parts in CATIA, I cannot open the drafting function in Mechanical Design as it will appear a "Runtime Exception" warning which will need me to close the CATIA. I don't know if this has anything to do with it or not but I noticed too that I cannot see the graphics format in Options>Compatibility. How to actually overcome this problem? I have done a few methods to solve this problem that I get online, but none that is similar to my problem and able to solve it.
