Using Add Component does not correctly associate with reference plane

Thanks for looking into this.

How would I set the workplane or rehost the object after creation? I can’t see an obvious way to do this from searching around the component list or online. Attempting to set the Work Plane parameter using the Element Parameter block returns an error ‘Can’t set parameter. “Work Plane” is read-only’ - which I suppose I’d sort of expect because you can’t edit this parameter directly in the Revit properties window either.
