AndrewSopher Posted March 31, 2022 Share Posted March 31, 2022 Hello, I was wondering if there is a way to create a reverse ledge in the foundation (walkout basement). I only want the ledge to be 3'' in height and 2'' in depth. It allows us to get the grade higher, as well as allowing the floor to sit flush with the top of wall. I have seen the tutorial for brick ledges on the exterior but nothing for a reverse ledge (facing the interior of the house). This is being used in a walkout basement for reference. Thank you. The attached image is not drawn to scale and is obviously missing a few key elements to the foundation but it is just there for a easy reference.

javatom Posted March 31, 2022 Share Posted March 31, 2022 Open the wall and check "pony wall". Make the top wall a 6" wall and the bottom wall 8". 1 Link to comment Share on other sites More sharing options...
Joe_Carrick Posted March 31, 2022 Share Posted March 31, 2022 Are you really still using X8? I would have no idea what was capable back then. Link to comment Share on other sites More sharing options...
AndrewSopher Posted March 31, 2022 Author Share Posted March 31, 2022 The only problem with using a pony wall is that I already have a pony wall set up because it is a walkout basement and I want the top part of the wall to be siding, while the bottom is the foundation wall. I am using x13, I am just not under my companies profile which is why it shows that. My apologies. Link to comment Share on other sites More sharing options...

Cannot change it to a pony wall because I already am using a pony wall to create a walkout basement (stepped foundation). Upper half is siding and lower half below the grade is the foundation wall.

Upper half is siding and lower half below the grade is the foundation wall. This is the problem with using "Floor Level 0" as the "Walkout Basement". If you insert another Floor and make "Floor Level 1" the "Walkout Basement" you will be able to add the Pony Wall to "Floor Level 0" which should be reserved as the "Foundation". Using this scenario: Floor Level 0 = "Foundation" Floor Level 1 = "Walkout Basement" Floor Level 2 = "1st / Main Floor" Floor Level 3 = "2nd / Upper Floor" I also have another Floor below the "Attic" which is usually just 1/16" tall but allows rooms to be defined at that level. 1 Link to comment Share on other sites More sharing options...

That makes a lot of sense. Thank you for helping. For the brick ledge (floor level zero in your example) Would I just do another pony wall, top wall 6" and bottom wall 8''?

I'm not sure if that would work but maybe..... Link to comment Share on other sites More sharing options...

chiefuserids Posted March 11 Share Posted March 11 I created the wall exactly as described. No other adjustments. The 3D rendering is exact. Link to comment Share on other sites More sharing options...
