Set Group origin point

Hey guys,
Is there a way to establish the origin point of a group when creating it in grasshopper with the Select Element component? I think by default it is assigning the origin as the centroid of the geometry
by group origin I mean this arrows in revit that allow you to change the insertion point of a group

As far as i can tell this is still a wish list item on the Revit API

Hi @Japhy ! I wonder if there is any way to get the Model Group Origin XY as a plane using RiR?
Right now It seems I can only get Worlds aligned plane for same groups that are actually rotated, I guess the plane also has to be affected then…

Hi Mykyta,

Try casting each instance directly to a plane.

Thanks for advice, I tried to test it on Model groups that are in Link instance and it seems that orientation is not collected properly, so I guess this method only works if model group is in current document but not in linked one. Is there any workaround for groups in Links? :slight_smile:

Hi @m.onopko,

There is actually no API for this. We have a solution that use to work both linked and non linked groups but is not working anymore since Revit 2024 on linked ones.
