This Rhino Grasshopper stair tutorial uses a simple loft surface to model a series of parametric stairs.
First, you model the base curves in Rhino and use the loft command in Grasshopper to make the surface. Then you will use the Contour command to make the stairs curves and use an offset component combined with extrusion to finish the model.
This is just one of a series of courses by Parametric House that you can enroll in.
