Do you mean making it so that if a multiple selection of arbitrarily rotated, non-gridded parts belong to a building, ALL the relative axes of the multiple selection (not just the vertical one) are parallel with the building's axes? If so, then yes, ONWARDS to the full fix!
But even just going back to pre-1.10 is still a VAST improvement over 1.10.
I note that the 1.10 version (all axes averaged) is still available as an option in 1.10.1. I'm VERY puzzled by this. First, it means that the 1.10 change was deliberate, not an unintended consequence of a change elsewhere. It also means that somebody at Frontier not only thought this was a good idea to start with, but STILL thinks so despite the customer feedback to the contrary.
This makes me curious. There must be some advantage to the 1.10 system I can't see. I wish the person responsible for this change would elucidate on how averaging ANY relative axis, let alone all of them, is beneficial in any way whatsoever when the parts involved belong to a building. This is a total mystery to me, but if the 1.10 system somehow makes life easier instead of harder if you know how to use it, I'd love to learn that trick.
