AC21 - upper slab-stair's connection

Hi,
playing (and working) with AC21, I'm now facing some difficulties in how to make simple and common things.
Now I'm having issues modeling the simplest (for RC structure) upper-slab to stair connection without using SEO.
Can anybody help me, please?

I found a possible way but I think there's a malfunction or bug in the tool.
Look at the picture

There is something not right with your ARCHICAD version.
In the INT version, Monolithic Flights have a 4th Connection Type, which would provide the necessary settings to solve this connection type. See the attached image.

Also, there is some glitches in the interface, those gray circles should be overlapping parts of the Stair Section, not be to the left of them.

Laszlo, he glitches are due to win7. In win 10 I don't see any issue.
The fourth connection appears when the stair ends with the treads. When it ends with the riser you have only 3 connections.

Hi All,

It is currently only possible to do that with SEO (the same settings you use in the first picture, but subtract the slab from the Stair). We plan to add a connection type like that in the future though.
