Doesn't help you in multiple models, but at least within one model it keeps the center of that part consistent.
For submodels, I use the same principle: set the origin of the submodel to a likely rotation point.
I have done similar things works nicely.
Quote:Finally (and I had frankly forgotten about this), in the Selection Center context menu, you can jump the selection center to the different snap positions of a part (assuming it had snap info), which is likely to include a natural rotation axis.
This is exactly what I was thinking about. Using part snapping info to find the right selection center point in an easy way
and then using rel grid alignment (if not already correctly aligned) for getting the right axis.
Thanks for pointing this out to me. I did not find it in the current version (LDCad 1.6d V2) but then I tried the latest alpha (1.7 Alpha 2a) and there this brand new option was there.
Very big thanks to Roland Melkert for implementing these very useful options (in the Selection Center). Saved my day and it is a game changer for me!
