Roof cutting exterior wall height

[CrippleCreek]

Using Pro 2020 When I select roof--build roof planes the rafters cause the exterior walls to shorten and the ceiling is chamfered. How do I maintain exterior wall height while using the auto roof function?

The Auto Roof Builder uses ceiling height to determine where roof planes go.

 

Posting images and your plan file (close Pro first) will help others help you.

Thanks for the prompt reply. I have set my wall heights to 8' but after using the Auto Roof Builder they become shortened (last time to 82") by the program. Walls in the interior are unchanged.

I started using program about a week ago. Not sure how best to send images of problem. Attached is a word file with image of problem.

Attached plan, but due to size program may not accept.

Looks like making the deletions reduced file size enough to upload. 

Thanks for your help, Warren

Thank you that took care of the problem. I tried all sorts of fixes none of which worked. I think the program kept the old roof baselines and kept building the roof off of them. Even deleting all the roof sections and regenerating them did not work. 

Eric, Thanks again Warren

Roof Baseline Polylines must be created by the user by checking the box in the Build Roof dialog. They control how the roof builds, but as you found, are not connected to the roof.

 

They often cause these type of problems. I'd suggest only using them in the rare case they are truly needed.
