@Klaus, it would be nice to test the addition of a Datum Plane... this item is much similar to a Face, so probably it would be much easier to add constraints to this kind of item compared to LCSs.
Yes, having selectable geometry as such plane could ease making new constraints for that.

As an alternative, the Datum Plane could be imported as a Plane (as I simulated in my attached file)...
Perhaps this is a very good idea. What about importing a LCS and converting it to some kind of interface with 3 axis, 3 planes, a center point. Everything being seperatly selectable for doing constraints ? I think it is less work for users to work with a LCS instead of placing several datum geoms.

I think a start could be done with a Datum Plane imported as a Plane.. this should be quite simpler to be implemented and could be used immediately by a large amount of users (many of them are already using Datum Plane as a reference for their Body Part Designs).
This could already solve some topological issues, removing the link to deleted/renamed faces and introducing the link to Datum Plane faces...

This would be an other big improvement. I like the idea of the conversion to adapt the Datum items to A2p constraint mode :D

I started to read a phython tutorial for beginners. But i assume it will take weeks before i will be able to even read and somehow understand the code of the WB. Not even talking about contributing yet. But I’ll give it a try.

Thanks for the open discussion and your consideration.
