Cannot un-bury the joint

[sutcac]

I don't think it's a matter so much of unpredictability, more a matter of understanding how Chief models things. Not saying my understanding is superior, only that I think your situation is likely predictable.

Personally, I can't see why anyone would even want a half post against a wall like that anyway. In every similar situation I have ever encountered, that post would be fully buried in the wall.

As far as the floor platform, the discrepancy could be easily altered in the views that matter like the elevations, sections, and floor framing plans.

But it would help I think to post the plan.
