Stairs

Does anyone have a template for stairs with stringer, treads, and riser? If not is this something that could be done in the future? I was thinking something along the lines of a sloped area

I'm going to put this out in hopes someone in the community can help improve a solution to this idea. We can get a count of specificĀ board lengthsĀ for your stairs using formula that calculates the total linear footage required and divides it by your stock board length. Set up your item properties and use the following mapping:


  • [StairRise] (Height of one step)
  • [StairRun] (Depth of one step)
  • [StairWidth] (Width of the staircase)
  • [BoardWidth] (Width of the board you are using, e.g., 5.5)
  • [BoardLength] (The length of the stock boards you are buying, e.g., 8, 10, or 12)
  • [Spacing] (Gap between boards on a tread)
  • [Waste] (Unused percentage of each board)


This formula calculates the number of boards needed by finding the total "tread surface area" and converting it into pieces of your stock lumber:


ceil((([Area:SF] / (sqrt(pow([StairRise]/12, 2) + pow([StairRun]/12, 2)) * [StairWidth])) * (ceil([StairRun] / ([BoardWidth] + [Spacing]))) * [StairWidth] * (1 + [Waste])) / [BoardLength])

Stairs Concrete Formwork. Ecoply Wood.

Ecoply Wood is 2.88m2 per sheet (1.2m Wide x 2.40m long)


([Point Count] * ((([Num of Risers] * [Riser Height] * [Stair Width]) + (2 * sqrt(([Num of Risers] * [Riser Height])^2 + (([Num of Risers] - 1) * [Tread Depth])^2 ) * [Stringer Thick])))) / 2.88


Concrete Required Formula

sqrt(([Num of Risers] * [Riser Height])^2 + (([Num of Risers]-1) * [Tread Depth])^2 ) * [Stair Width] * [Stringer Thick]
