and I found another workaround - create the perimeter with thin walls first, add doors and then convert the wall type to thick wall.

Finally got it working (in a way) with room dividers and changing the wall thickness. Not 100% accurate - but good enough. Thanks again Eric, for pointing to right direction!

Thanks Eric! I tried room dividers, but that did not help I'll attach a plan. Koidula 11 V1.2.plan

Here's the issue I have - I have this weird corner case of walls with multiple angles. As shown in the image, the underlying CAD has a door and I just cannot resize the exterior door properly. I think it is because the walls on left and right just kind of run into the diagonal wall and block the resizing of the door. I tried editing wall intersections but that did not help. The side walls just snap back. Any ideas how to solve the issue? Right now CA allows me add a door with 339mm width, but I need 700mm width.
