Hi, I have created a single drawing for 10 assemblies and made a table showing the varying dimensions in the assemblies. I haven't checked into commonsapce yet. In future, when i checkout all the models should be checked out. I donot want to add all the 10 assemblies in the drawing as this will take a very long time to open the drawing. My concern is, can i use a intralink relationship to attach all the 10 assemblies to this drawing? if so, should i use unplaced member, or user defined relationship. thanks raghu
