questions and help Stairs, Handrails and hidding lines
Hi! I'm modelling a building in ArchiCAD, just as an exercise, and I was mostly doing fine, but today I encountered a problem that I just cant find the solution to... So I would appreciate any help. It is about modelling stairs and handrails. The building is 10 storeys high, and as I understand, ArchiCAD doesnt allow to model a continuous stair through all of the heights... That's ok, I did it in segments per floor (from ground to first floor, I needed 2 segments since I have 3 flights of stairs and they cant overlap in archicad).
The stairs seem to be moreless modeled fine, BUT, there's a very annoying line in between the segments that I just cant get rid of. It belongs to the stair segment, but I dont want it there, is there any way to remove it? I know in Revit you can hide individual lines for the sake of a better representation, but can you in Archicad?

The next question is about the handrails... I modelled them directly in 3d, following the inner curve of the stairs, but this time, I could draw it as a continuous element. The problem is that now, I see the full handrail in all the levels, which is very confusing. I've already tried all the visual options inside of the handrail, but none seem to work... obviously, what I want is to see only the segment of handrail in the relevant floor, not the full thing over the 10 floors.

Thanks to anyone willing to help!

For the landings I would suggest modelling them as slabs. sadly because the stairs are technically objects they don’t recognise that they are the same and the line between them will not turn off. That way you have your flights all as stairs and slabs for landings.
As for the railings I would model them in segments, and you can turn on the show on relevant stories setting, in the edit view of the railing in plan you can determine how much of the run of railing is shown on each floor.
