How to Calculate Circular Stair?
- Step 1. Choose the measurement units, DU — mm, cm, m, inches, feet.
- Step 2. Choose the drawing color, CL — monochrome, color.
- Step 3. Choose the staircase type — left turn, LF, right turn, RG.
- Step 4. Input the stair, stairwell dimensions — total rise, Y*, staircase diameter, D**, staircase internal diameter, ID, Angle, A.
* from the 1nd floor level to the 2nd floor level
* total rise = stairwell height (if top step is on the 2nd floor level)
** staircase diameter = stairwell diameter
*** staircase internal diameter = stair width
- Step 5. Input the steps parameters — quantity, Q, thickness, SW, nosing, SF*.
* nosing = tread overlap
- Step 6. Please check all entered values, click the «Calculate» button and get a Circular Staircase design.
