Stairs

 

Both spiral and straight stairs can be generated in form·Z. Both styles can be supplemented with railings and other features.

 

Spiral stairs can be generated about a selected axis, with a single click of the mouse. The axis can have any orientation, which allows you to generate even upside-down stairs, if you seek special effects. The length and height parameters of the stair can be set in a variety of ways, including total height, number of steps, riser height, and number of cycles. Spiral stairs can be supplemented with railings, easily derived from lines of the stair, which can be used as paths for sweep operations.

 

 

Straight stairs are generated from a path line drawn by the user. A number of variations are available, such as those illustrated below.
