2. If required, give the new stairs a Name.

3. Check that the default settings for Stringer Depth, Stringer Thickness, Width Between Stringers, Landing Floor Thickness, Posts and (for Height & Angle specifications only) Angle are suitable. Change them if necessary.

4. Enter the coordinates for the origin of the stairs (that is, the midpoint of the lower front extremity) in the Position text boxes, checking that the Wrt entry refers to the correct reference axis system.

5. Set the Direction (as viewed when facing up the stairs).

6. Enter the Height and, for Height & Length specifications only, the Length. Note that the specified length refers to the horizontal projection, not the actual length of the stringers.

7. Click OK to create the stairs, complete with appropriate handrails.
