Field notes
The homepage groups the 16 listed designs into steel, wood and concrete, with examples ranging from sawtooth stringers to spiral and winder stairs. It says calculations update as dimensions are entered, and that the same lettered parameters appear on the drawings. For code checks, users can select from listed options including IRC/IBC, Approved Document K, NBC and NCC; suggested dimension adjustments are described as one-click changes.
