Hello,

       I just want to confirm if my understanding is correct.

       ModelDoc is for handling Assembly(3D).

       PartDoc is for handling Part/Component(3D).

       DrawingDoc is for handling Drawing file(2).

       I have been using these for a while but since all of the programs I'm handling are for maintenance,

       these codes already exists when the program was given to me.

       I just want to understand the concept.

       Thanks in advance.

Best Regards,

J.Torres
