You should explain what your issue and resolution was in case anyone else has the same issue and stumbles upon this thread.

I assume you have two Single Plane Roofs which each trimmed the wall under the other? The main downside of using Trim is that you need to break any walls that extend beyond the cutting boundary of the roof in question, and that you cannot Trim en-mass for the same reason above.

Ling.

fyi. You can do a Gable Roof by setting the two ends of a Multi Roof to Gable.

Thank you for your response. I had managed to resolve the issue earlier — the cause was the reference axis, which was positioned at the highest point of the roof.

So you just moved the Reference Line and adjusted the elevation down to compensate and it resolved? Odd... sounds like a bug with the clipping box.
