Smart Stairs is a Python based, parametric stair generator for CINEMA 4D.
Many types
Smart Stair comes with several stair types which can be switched on the fly.
Multi - stairs
Multiple stair segments can be managed by nesting Smart Stair objects - Smart Stair automatically handles connecting those segments by a platform.
Parametric
Smart Stair offers convenient viewport handles and a variety of parameters - all of which can be animated or scripted.
Editable
Link your own steps, rails and materials or just collapse a Smart Stair object to get a hierarchy of instanced, editable objects.
Compatible
Smart Stairs supports Windows + MacOS 32/64 Bit and needs CINEMA 4D R13.058 (or newer).

Would also be tankful... if there's any other procedural tool for making stairs (as the old QuickStairs).
