Hello,
I would like to snap & lock two bodies so when i move one the other moves along with it, but i don’t want to union them because i lose the edges. see attached photo.
thank you
Yoav

At the moment we don’t have a setting for that. Can you help us understand why would you like to keep that edge?

This element will be manufactured from two bodies separately and I wound to show that in the model. Also to be able to include the welding lines (via fillet/chamfer).

Then you should not union them indeed. The best solution in this case would be to add them to a folder, and just select the folder when you want to move them together.

Ok. I will use this.
Do you think in the future there would be constraints options to the 3D modeling as well, similar to the sketches?

Yes, we will have assemblies in the future.
