Yet another wall clean up issue

Paul King — Wed, 08 Mar 2023 04:44:23 GMT

I have inherited an ArchiCAD 26 model in which composite walls will just not clean up based on materials priority. I am sure I am missing something obvious, but cannot seem to put my finger on it.

Per the screenshot below, a timber stud wall simply passes over a wall containing concrete without the materials interacting in any way, even though the wall reference lines touch.

The concrete material has a higher materials priority than the intersecting timber material, while the plaster board linings for each composite wall all have the same priority - so based on that I would expect the stud wall timber to be cut short by the concrete material , and the plaster board to heal either side - but that is not what happens.

The walls are all on the same story, and have the same 'new' renovation status.

Under Project Preferences/Legacy, walls clean up is not set to 'Legacy' mode (I tried it, and it does not help)

What am I missing here?

I have attached a module containing the walls, in case that helps.

Same Layer Group?

Walls in different layers with different (or zero) intersection group numbers?

Bingo! Yes, the layer combo for the view had wrong intersection priorities set (freelancing for new office & with unfamiliar setup - suspect their template has been in use for quite a while and may even predate materials priorities being introduced into ArchiCAD).

Thanks guys!
