Snap selected to active
This is a re-make of blender's native snap selected to active. There are some differences:
- Can properly snap objects that have a (single) child-of constraint.
- Can snap single object to 3d cursor.
- Can ignore/inherit location/rotation/scale in a similar manner as the snap features found in machin3tools.
There is also an opt-in in the pistonpusher pop up menu(shift+e). It's called Auto-constrain It automatically adds a child of constraint after you snapped objects.
