I'd like to add that it's also important how they intersect. The reference blue lines need to intersect.

Hi,I had similar problems, although it happened when I went from 2D to 3D every time. I assume it was because my model had irregular walls and therefore it was very complex. My "solution" was working in axonometric view. I don't know why or how, but perspective was all white...

Hi, I am not sure from this pictures, but could it be possible that you trimmed the wall down? Like, if you rotate the view, would the wall be visible only up from the dormer roof?Usually archicad asks you if you want to trim up or down and it selects depending where you cli...

Hi I don't think the problem is in joints, but rather in the pannels. I tested it and the joints follow the curved line nicely, however the pannels just "connect the dots" - joints - in a straight line. I believe that the effect you're going for is how to bend the pannels. I...

HiI'm not sure if this would be helpful, but what I would do is make different wall composites to control the thickness and then stack shorter walls on another. Then it is possible to change the thickness rather quickly, and overwriting the colours.
