How to solve this problem with ToolsOnSurface or JointPushPull? (Because those extentions are what I already installed but don’t know how to apply it on this matter)
No no, I already draw that part, what I want is the frame to hold the roof. 3 x 3 cm. But diagonally, and the point A to point B has a different surface (rectangle and doughnut)
I only clipped them at the top. I pulled the top ring out of the group and made it a solid component. The rails running down to the corners are solid components as well. Then I used Trim in BoolTools 2 to trim the rails to match the ring. If your model was cleaner and all of the objects were solids, the lower ends of the rails could be trimmed the same way.
