I never saw anyone answer this, but doors, windows, walls, and objects all have parentIdentifiers. I did confirm in a session that the door I scanned did have a parent identifier that belonged to the wall I scanned with it. So it works and yes, they use parentIdentifier to link those objects. I just want to see how to get the position of that door or that window inside of the wall as well. I still haven't found that out.

How are you getting your positions? I'm looking at this sims_float3 dimension and I don't know how to determine a length of wall for instance. But I see you have a wall.transform.position in there and I'm curious how you got that position?
