Hi Visualarq team or anyone who can help.
I have a question relating to the creation of spiral stairs in Visualarq grasshopper.
"The process of creating a spiral stair is the same as creating a normal stair. The only difference is that you need to pick an Arc as the spiral stair path. "
BUT it also says
( Note : Spiral stairs can’t be created from a path that makes a turn bigger than 360º. So just take that into account when you set the number of steps, or the step tread dimension, because these values may make the stair turn more than 360º and it won’t be generated.)
So I’ve tried to keep the steps down and only make half a circle. (see screenshots) As you can see the same GH definition works for straight lines. Note its all in inches.
Its just not working for me. What am I doing wrong?
Im not sure if I need to change the crv param to an arc param?
