Spiral Stair

[Ghassan Kanaan]

Is it possible to have the same start point and endpoint for a Spiral Stair ? Wich means an angle of rotation of 360º. I tried..it didn't work.

No, has to be split into two in my experience

Some years ago, i tried to solve this in GDL and it went really far, but i didnt get it to a really usable end, because i wanted to put in far too much possibilities.

But - the "core-idea" of it, in fact -  is working so far pretty smooth and if someone in the world would like to finnish this spiral stair - just jump in and code on it.

Can you please explain your method of splitting the spiral stair in order to avoid that gap between the start and endpoints.

Thank you

Thank you very much for that interesting video. Unfortunately the pln file you joined here bugs every time I try to open it.

I tried to download it for my dropbox like everyone else and opend it from my running Archicad25 Edu-Aut-Version - no bugs - everything ok.

Amazing Archicad still making such a crap and havent sold that problem.

it so long time. 6 years for now. To make a 3 floor stairs you have to make 4 stairs. absurd. 😄

You have to hack to make a normal stair.
