Hey friends,

I am trying to automate staircase calculation and for linear stairs I have produced some satisfactory parametric results, but I can’t figure out a way to create those harmonic shifts in step shape round the corner. I need to manually walk through the middle line (dashed one) and then do all the fiddly geometrics stuff, yet I’d prefer to just enter some variables and let Shapr3D do the rest.

The variables contain XYZ of the room and based on some norms in Germany I determine the number of steps and raises, the breadth of the steps etc.

As I said, no problems with straight stairs, they are fairly easy to calculate and reproduce. If you are interested in those, drop me a line below.
