1. In the help menu, search for
"Custom Stair Based on Manually Drawn Elements".
2. Another approach is to create separate stairs for each section if they are standard and then use a slab to create the landing
3. Create all steps and landings with slabs and/or other 3D elements
4. Use archistair by Cigraph, I believe free for students

5. Cadimage out of New Zealand has Stairbiulder; I'm not sure what their policy is for students
