Good to know

  • If you change the floor height, the number of steps stays the same and the riser changes.
  • The window shows violations in red with numbers. Fit to the nearest valid values corrects the number of steps, Fit to the room adjusts the steps up to the wall if the flight runs into it.
  • Default rules: riser from 15 to 19.5 cm, tread from 24 cm, step two risers plus tread from 61 to 63.5 cm. These are commonly accepted limits, Russian standards are not built in separately.
  • You set your own rules in Project settings, in the Stair rules section: riser, tread, flight width, step 2h+b. If Flight from is 0, the width is not checked. Defaults restores the commonly accepted limits.
