I’m not seeing a way to do this but I can’t say I’ve ever tried to do this before so I may be missing something.
Basically what I’m trying to do is create a group extruded in the X direction so that the material is applied properly. Then I would like to somehow rotate it so it is vertical and then grab the handle for the group’s definition and generate copies with the add_instance method.
One way to do this is to simply leave the original group unrotated and then rotate each instance vertical as they are created but I would like to try and eliminate this additional transformation if possible.
I don’t see a way to do this unless I somehow can change the definitions axes.
