I think I am starting to see the light. So the proper process should be to set my pitch (to the lowest pitch in the project) AND calculate and set the top to fascia before I draw any roofs. Then if the pitch increases on a new roof section the heel will increase and top of fascia will be constant? Is there a way to tell Softplan to keep the bearing and automatically adjust top of fascia when you first set up to an new pitch?
Thank you all, very much!
