Complex Profile Beams "Flipping" after Back-Saving

Jeff Griffin

I've noticed that certain complex profile beams end up in the wrong orientation (mirrored 180 degrees about the reference line) after back-saving to previous version. Specifically, this issue seems to show up at the point I save from AC22-to-AC21. (AC24-to-AC23 and AC23-to-AC22 seem to work fine.)

These particular complex profile beams are ones that I've made to show fascias. To work as efficiently as possible, as I place these complex profile beams, I mirror them about the ridges, since most of the time the roof slopes are symmetrical on both sides a ridge. It's been several months since these complex profiles have been originally placed so there's no way to know for sure, but I suspect that the ones that are now in the wrong orientation (after back-saving) were ones that were mirrored across ridges when I had initially placed them. Approximately half of the rest of these beams are in the correct orientation.

Interestingly, when I open the AC21 version using AC22, the issue can be seen. When I open the AC22 version in AC22, everything looks fine.

Here's the whole progression, from AC24-to-AC21 if it helps:

I've already tried opening & repairing the PLNs along the way to see if that would help, but it didn't make a difference.

Any ideas what may be causing this defect during the AC22-to-AC21 back-saving step, or how I can resolve it?

Thank you,
Jeff
