Procedural Stair

It has many features:

1. Step count and density
2. Step dimension
3. Railing height
4. Railing Curvature
5. Stair overall width
6. Switch between two Railing support
7. Switch between two bases.

Geometry is optimized.

No Boolean operation is done for the efficiency.

This stair is a part of the course I published here on Blender Market.
