Tom315 Posted January 29, 2021 Share Posted January 29, 2021 I understand furred walls when it comes to EXTERIOR foundation walls. Which has a foundation wall on the exterior, and an interior wall on the interior. But I'm trying do design a house with a few INTERIOR 8" foundation walls...around a safe room. And I'd like to furr both sides of those walls with 2 x 4s. Which means "triple walls"...about 16" thick. But Chief will only let me "marry" TWO walls...not three. I can set the middle (foundation) wall as "frame through" and both of the outer (interior) walls as "Furred wall"...but any door or window only penetrates a (seemingly random) 2 of those 3 walls. Is the only workaround to insert the third wall as "frame separately"...and then insert a doorway or window opening? Link to comment Share on other sites More sharing options...
Doug_N Posted January 29, 2021 Share Posted January 29, 2021 And Eric knocks it out of the park! I was just about to suggest that when I read your reply. Link to comment Share on other sites More sharing options...
Tom315 Posted January 30, 2021 Author Share Posted January 30, 2021 The concrete contractor and the carpenter are different folks, and there are more interior walls than just the furred ones. So I was hoping to have a "concrete plan" with foundation walls on one layer/plan...and a framing plan on a different layer/plan that also includes the furring...with each plan having its own dimensions.

joey_martin Posted January 30, 2021 Share Posted January 30, 2021 I do many of these. I have a 4" interior wall that only has drywall on 1 side. Just draw in in and butt it up against the foundation walls. Use layer sets to separate the 2 plans. Link to comment Share on other sites More sharing options...
joey_martin Posted January 30, 2021 Share Posted January 30, 2021 And yes...doors and windows will recognize the interior wall and make the appropriate cuts. Link to comment Share on other sites More sharing options...
