When I import STEP files I have a series of parts which form an assembly. Since there is no mate information in the STEP file these parts may move apart if I am not careful. Although it is possible to lock all the parts together (one to another) this is very tedious if there are hundreds of parts. Is it possible to put a 'global lock' around a group of parts or is there a proper technique which I should be using. Thanks in advance for any advice.
Kind Regards, Barry.
