Apologies if this has been addressed already or my forum etiquette is off, it's my 1st post. I'm using Home Designer Pro 2016. I have built a garage in an independent plan file from the main house. I did this as the roof kept changing the main house roof every time I modified it. The main house also has the terrain perimeter embedded. So I have a garage plan (file) and a house plan (file). How can I copy all of the layers/levels of the garage plan and paste it into the house plan? I saw a thread that mentioned the "edit areas - all floors" but I'm still only able to copy and past one layer/level at a time. Any help is much appreciated. Thanks in advance!
