I have a step file generated by a vendor. There are ~10 parts in the assembly.
It opens just fine. The assembly looks perfect with all parts installed and in the right place. Then I save and all of the parts and assembly file are created in the same directory as the step file (my choice). When I re-open the assembly file, all of the parts are grayed with the message "This part cannot be located". Funny, beacause I can right click on the grayed out parts and select "open" and they open just fine. If they cannot be located, why do they open?
