Stair & Slab Joint

[Yan Naing Bo]

Any idea to join slab and staircase into one piece.
I would like to do as attached, in my project.
Please kindly help me.

Unfortunately (wish listed), Join geometry doesn't work between Stairs and Slabs.
You have 2 solutions :
- Specify slab thickness but negative value of type parameter "Extend Below Base"
- Add a slab edge profile
But in both cases, play with Linework (LW) tool to override common lines as invisible.

Thank you very much indeed!
