Wall Trimming Issue

[Anonymous]

Hi.

I've created a complex profile which is a straight wall with a curved roof section as in the picture below. I want to then use solid element operations to trim the walls down to the level of this complex profile 'roof'.
The trouble is that for some reason one end of the wall doesn't want to extend to where it should be (see plan view).
Is there some sort of trimming/ priority option I can change so that the thicker wall with the roof attached takes priority over the thinner wall? o.0

You can set the complex profile wall's Priority (in wall settings) to be higher than that of the upright wall, OR change the reference line of the upright wall to the top face (on your plan image) and the complex profile wall will extend to that line.

Thanks, It seems to work if I set the reference line to the center, but not to either side. Any idea why?
It's fixed for now at least.

Where are the reference lines of the non-composite walls?

They're all set to the interior face.

Are they on separate layers with different layer intersection numbers?

Hmm, no. How do I set that up?
They're on the same layer.
