STAIRS first and last flight

[davor_r]

Hello,

Where can I find changing the height of concrete part of the first and last flight? It seems that all flight-start connections are not aplicable for me. Vertical cut is what I need, but it can not change the height for coonection with floor slab.

Also is there any other way that I can set reference line on core (concrete) part, and not default finish part? Picture in attachment.

Based on the images you posted I think you should just redefine the Composite Structure used for the Slab and then you would have what you need.
About the Reference Surface: Unfortunately, the Stair Reference Surface is always at the front and top of Treads and cannot be set to the front and top of the Stair Structure. This is something I personally wish was available because I think many times it is more intuitive to work with the Stair Structure.

Thank you Laszlo for answering. I draw slab just with two fills, to represent what I needed. Actualy, I need to change height of first riser. For example, on floor I have 10cm of composite skins above the structure (reinforced concrete slab). It means that my first riser should be those 10cm of floor skins plus cca 15cm of structure stairs, and than finish of cca 2-3 cm. But for now all of the risers have the same height.

Also I need the last riser to be 6-7cm od structure, and floor skins of 10cm should cover stairs, so the final height od the last riser, should be 17cm, like all others.
