As a full time builder and part time draftsman for my own homes, I have failed to import the new walls into my updated softplan. Done for several years in fact. Out of frustration, I decided to redraw from scratch and have found that a lot of my "problems" went away. Especially for roofs.
Just wanted to share. I am still working on trap windows and would appreciate any and all help.
I really like this site and keep it up all the time my computer is on.
