About 1.5 years I drew an addition for a client. Now he wants to add a detached garage with a mother in law suite above it. The tricky part is that he wants to see a rendering of his existing house and the addition prior to completing the plans. I've already given him a rough rendering of the garage. Is there a simple way to do this? Or is importing the old drawing into the new drawing the only option? I really don't like combining plans on one drawing if at all possible.
