Hey all,
I'm a homeowner (commercial electrician and Biomed, so some familiarity with Autodesk / CAD products... but just enough to be dangerous) and trying to build a digital twin for my home from the architectural drawings. One of the features we have is a "foundation ladder": a dual 2x4 rebate in the concrete which, with a quick bit of searching, I was able to figure out is fairly unique to western Canada (I'm in Edmonton).
For the top 3.5" of the foundation wall the width is reduced from 8" to 5" to place 2x4s (one inside and one outside) that the vapour barrier and then OSB ladder cap (essentially the sill plate) and insulated rim board then sits upon.
I just have no idea how to get CA to build this. I've poked around in the sill plate options, wall coverings don't seem to have a thickness option
Also a little stuck on how to define the OSB ladder cap and insulated Rim board in the sill plate options. Under the Sill Plate Framing Member Defaults, I don't see an option for OSB (although PSL is close... and unsure about Eng. Lumber option.) But then the rim board is also ... part of the sill in a way? It's certainly part of the basement as the joists/beams for the main floor are at that same level (inside the basement ceiling) sitting on top of the foundation wall, and then the OSB flooring is laid down on top.
Any thoughts on how to best approach this would be appreciated!
