Just plan file much smaller

If you share your plan file I can have a go at it

Have you watched this

Use elevation lines to form swale drain.

I had a go at it ,I can only get it with manual roofs I don’t think it’s possible with auto roofs, but a smarter user might be able to do it.

Compress it or drop box or other cloud storage

Share your plan it will make it easier for others to help

Can you share your plan file you should get a quicker solution.

Share your plan you should get a solution

Chief architect has lots of training videos you need to watch them they are really helpful if your ssa is not upto date there is a lot on you tube as roofs can be tricky at first The walls you want to be gable, select the wall turn on gable with its toolbar also you can open the wall go to roof tab and set as gable.

See if that video gives you what you need

Does that get you what you need, check attached file I just finished it with manual roof. Working.plan

This video show what happens with overlapping height data

Also turn on attick walls there is one that messing with that intersection I found the problem went away when I deleted the attick walls if this is a suitable thing to do

To start with the file uploaded has no foundation so maybe its the wrong file, Jims screen shot show what to adjust.
