Would wall material region tool help with this

Could you share your plan it would be easer to ell you what is wrong

Also the footing just turn it off under wall dialog foundation tab.

Forget dynamically just build terrain then turn of auto build terrain edit the retaining wall jobs is done, editing the retaining wall is a bit strange but it works, it seems like it is crossing over it’s self but ignore it as it does not seem to matter

Is that what you want

If you are still using retaining walls make sure the default top and bottom are selected as if you have adjusted the wall top or bottom chief will no longer auto adjust there top or bottom positions to match the terrain

Upload your plan so you will get best help

If you mix glens smart idea with Make roof base polyline it works with auto roof and you can loose the invisible walls

Give this a go your model is way of zero position see if it helps Shaw garage.zip

Sorry i missed that this is the way chief handles those roof situations I don't know why this happens, but it does happen it has been talked about on this forum but I don't know there is way to get auto roofs to handle it. What i do is start with auto roof and then do a manual edit at the end rooftest.plan

I downloaded you file and something funny is going on I will investigate

Open the room dialog and adjust rough ceiling height

What this video or use automatic roofs with setting correct ceiling heights

Some times with imported terrains you can get away mostly only using major contours that makes it easier for chief to handle
