Dear Dialux Community,

I've bin trying to create a simple roof with a simple dormer in the middle for hours now. When making changes to the dormer roof part, suddenly there appear parts of a wall through the other parts of the roof and sometimes Dialux creates these strange triangles. This happens realy randomly and I dont know what to do anymore. I attached the project file for you to check whether this is really a bug or not.

Can anybody help here? Thanks a lot for any reply.

With best regards

Michel
