I tried Group.ByElement node, and it works, except the origin of the group is out a billion miles from the group. (It is actually located at the origin of the project).
I looked at the pyton script (in the node), and it seems pretty straightforward: anything in there I can do to make the group origin fall in the center of the bounding box of the elements? as what happens when you select and use the Revit Create group tool?
Any alternative way to create a group using OOTB nodes (I know, crazy…)?
