I have a stair that is a single run from first level to a mid landing, then splits into two separate runs from the landing to the next level. So far I have modeled it as two separate stairs to avoid the "two boundaries" error, but as I head towards CDs, I was wondering if there's a way to build this stair as one stair to avoid the visibility problems in plan? Right now the stringers continue through the landing (using a plan region to see the small stair). I've attached the stair as I have built it so far. Should I be building this in an in-place family?
*Still new at this stuff, so thanks in advance for the help*
