I am just starting out with linked models in order to keep my file smaller and reduce crashes. Our client would like to create a series of small "prefabricated" shops with different door locations and some roof options. I created all the models from the same origin - had the building in place, created the roof system, deleted the building and saved. When I link the drawings, the models no longer align. I do not see a way to align the various pieces, and trying to move the bounding box in SketchUp and waiting to see what happens is tedious. Not sure what I am missing? Any suggestions or links to additional tutorials would be much appreciated.
