Hi there
I'm trying to delete the roof of my model and recreate/retrace it. I deleted all the roof sections including the vertical sections, and to make sure I've deleted all the sections, I ran a heat loss calculation. However, the results showed I still have heat loss through the roof which is suppose to have been deleted. It also showed that I still have a large area of roof which I expect to read 0m2. How do I delete the roof sections entirely so that I have a clean slate to recreate/retrace a new roof? I'm concerned with the old roof still there, it will affect the heat loss/gain calc for the new roof.
Thank you
Kee
