a client of us has got autdesk inventor 5.3 and showed me some problems on a drawing. I have investigated that there is a part of the drawing that has been supplied by someone else and which has been imported from a foreign format (step). The client says: inventor has to work with foreign standard formats, if not it is an error on the product The vendor (of inventor) says: you have to work on foreign parts. It is normal that if you import parts from another format you lose some information and generally you cannot expect them to work without doing anything.
could someone explain me the general situation about working with multiple (standard) formats?
