Hi - I was hesitant to post this as I figured the answer would be some innocuous setting somewhere that I blithered over, but I'm really stumped by this. The rim joist and joist framing doesn't seem to line up with the wall plane. I can see in the example plans that this works perfectly there, but those were all done with Chief Architect, not HD Pro, so I don't know what that means.
I have this gap between the inside of the rim joist and the outside of the wall plane, which extends into the wall finish, and accurately shows up in the renderings as a wood strip on the outside of the floor level, flush with the wall finish, but looking kinda dumb.
Also, why would the joists not line up with the wall framing, as is shown in pic 2? I have some non-standard 2 1/2" LVL joists (2x1 1/4), but that shouldn't cause the joist to drive through the wall framing, right, or misalign on the bottom plates. Pic 3 is again a shot at the rim joist gap and the misaligned joists.
Clearly I'm spec'ing something wrong, but can't figure out what, thank you for your help.
PS: I originally posted this in the wrong area (under Tips & Techniques, as in 'I need some tips & techniques', but I was wrong) and was soundly admonished for it. I can now proudly tick off my first instruction experience by both Solver and Potter at the same time, an accomplishment at such an early stage!
