Complex profile wall intersection


Can anyone help with the cleanup of walls. I have made complex profiles, and I cannot seem to get them to intersect correctly.  I have played with layers, renovation filters, building material intersection priorities.  Working in AC26 on Mac Studio.

what building material (BM) are you using for the stud space? it needs to have a higher BM priority than the plasterboard (?) lining for it to be overridden.

A few things to watch out for.


'Clean wall and beams' option in on-screen options should be ON.

The walls should all be in the same layer and the intersection group number for that layer can not be zero.

If in different layers, the layers all need to have the same intersection group number.

The strength of the building material in the external plaster skins needs to be weaker than the central skins.

You can also adjust the 'Junction Order' of the walls to affect how they trim - especially when 3 walls join at the same point.

And the last image, looks as if your reference lines are not intersecting
