Multi-plane roofs bug

Anonymous — Tue, 23 May 2023 12:33:01 GMT

There is a bug in the multi-plane roof (AC7 5005).

I use a multi-plane roof with eaves overhang. When I try to offset the edge of one of the roof’s planes, strange triangular shapes appear at both vertexes of the plane. The size of the triangles seems connected to the thickness of the roof plane. And, as a side effect, all the dimensions, associated with the vertexes of the roof plane, disappear.

Kliment,

Can you please tell me the exact steps to reproduce? And can you show a screenshot of the roof settings? I am trying to reproduce the issue from what I can see in your post but I must be missing something because I cannot. Maybe the specific pitch and thickness have something to do with it.

Best regards,

I have a similar roof issue: after you split into single plane roofs, the "set vertical angle for the roof edge" function won't clean up hip intersections. This might be caused by the same problem kliment is having...

One roof plane shown is at 4/12 the other is 1/12 pitch. This result comes from using one roof to cut the other roof. When I draw each roof plane manually without using any cut operations, all is fine. Of course, I need the cut roof plane function to figure out where they intersect in the first place.

Mark,

Roof planes of the same thickness but having a different pitch will measure differently in the z-axis when cut vertically. It seems to me a matter of geometry, so I am not certain there is a bug here. But from what I gather Kilment's issue is not the same here since his plan view shows protrusion in the x-y plane.

Best regards,

I am sorry for the late reply, Nicholas!
It seems the bug originates from a corrupt file and does no appear when a new file is created. However, it appears on different computers if the same file is opened.
I could send you the file, if you are interested, though.

I realize my issue is completely different, but since I started here I will continue...

I have used 2 foot thick roof to better demonstrate the issue: Still using a 1:12 and 4:12. The issue is not a thickness of the vertical plane of the different roof pitches, it is an overshoot or poor geometric intersection produced by the trim roof to roof command.
