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.
