kwhitt Posted May 30, 2020 Share Posted May 30, 2020 I've got some 30 x 16 louvered crawl space vents (rectangular) that need to recess into the brick foundation to the sheathing layer. I keep getting the result shown in the attached picture. I suspect the problem is the pony wall foundation I am using to get a brick ledge. Any ideas on how to do this?

Thanks, Kevin Is that a window that you customized to make the vent? If so have you tried turning off the casing? Link to comment Share on other sites More sharing options...

Thanks Ryan - That works (sorta'), but I'm still not getting a rectangular cut-out (bit of jog at the top). Besides, the vents I am using have casing (historical home). Any other ideas on how to get it to work with the casing? Kevin Link to comment Share on other sites More sharing options...

Kevin not in chief at the moment but I bet in the framing there is an option that cuts out the concrete buckout like doors that maybe can be unclicked? Looks like the brick knows to go to the window but it is leaving space for "framing" in the buckout of the pony wall. Link to comment Share on other sites More sharing options...

That does help. At least I'm getting closer. If only I could adjust the top and bottom concrete cut-outs. Link to comment Share on other sites More sharing options...

If it is then its usually a brick or stone. Link to comment Share on other sites More sharing options...

Watch on YouTube: http://youtu.be/A0hKA-eLAwo?hd=1 Eric - thanks again for the video. I am having some trouble following your steps. The first image shows the current state before making changes to the wall. When I change the foundation walls as you suggest, I get an error stating "The main layer of existing walls will be moved to accommodate this wall type change" (images 2 and 3). Image 4 clearly shows that I've done something wrong. The result (image 5) are my walls moving and my windows disappearing. What am I missing?

Were I to approach it this way, I probably should have started with these walls as defaults. Link to comment Share on other sites More sharing options...

Which I have and changed first. It is still pushes the walls outward. I will attach the latest version of the plan in a .zip file (getting rather large at this point) in a subsequent post. I watched the video 3 times and have no idea what I'm missing. Thanks, Kevin Link to comment Share on other sites More sharing options...

Is this an alternative to what you show in the video or am I to follow the video, rebuild the foundation, and then place the vents? Link to comment Share on other sites More sharing options...
kwhitt Posted May 31, 2020 Author Share Posted May 31, 2020 Thanks Eric. Understand about auto foundation, however, when I make those changes, I now get a big mess everywhere. Should I just delete the foundation, make my walls changes, and then turn on auto-build foundation? Fortunately, I have made backup copies.

Think I got it now. I had some wall types other than Brick-4 and Brick-6. I deleted the foundation, changed walls to proper type, and auto-rebuilt. Thanks!
