Use for

Situation	Description
Image	Bottom quarter staircase including anti skid profiles.
Image	Staircase with rounded corner.
Image	Top quarter staircase.
Image	Top and bottom quarter staircase.
Image	Curved staircase.

Before you start

Model a slab with the option Create concrete slab which has the contours of the stairs, viewed from the top view.

Make sure that lines are available, which indicate the positions of the steps. This can be done by making a Reference Model visible or by positioning Construction lines.

Selection order

Select the concrete slab.
Pick two points for the direction of the stairs.
Select the lines that will form the steps of the stairs one by one.
Click on the middle mouse button twice.
