I am a new user and and put my as built in one file. I saved the as built as a remodel and made all my changes to where walls are and other modifications. Is there a way to overlay my remodel over my as built to see the changes? I have viewed a video that said that I was supposed to lock a layer set but I unfortunately didn't do that before I started my remodel modifications. Any help is extremely valuable as I really don't want to redo all the work I did? Thanks in advance.
