Last item here: the overall length of the stairs. Again, I added a panel showing the resulting tread length for better readability. Input A is our Gradient value, input B the result of Rise x 2. To subtract this Rise x 2 from our Gradient input use a Subtraction component: I prefer to use an external panel with the same data input (= 2) because it makes my definition more comprehendable. So first of all use a Multiplication component and input the result of our little Rise calculation:įor Rise x 2, we could right-click input B and Set Data Item = 2.

Rise and Gradient being given, we solve the equation for Tread: Tread = Gradient – 2 x Rise.

Which in our example translates to: 2 x Rise + Tread = Gradient.

The real-life formula is: 2 Risers + 1 Tread = 60-65 cm (Comfort Rule).

Now for the Tread: This one has to be calculated based on Rise and our Gradient input:

Rise, Tread, Overall Length <īased on our inputs we’ll now calculate the Rise and Tread values plus the overall length of the stair.įirst, Rise – that’s pretty straight forward: Use a Division component with Number Slider Floor height and Number Slider Step count as inputs:Īs you see I added a Panel to check the result and again grouped the new components. You’ll find more learning resources here. See my article on Starting with Grasshopper. Let’s group these sliders and call it Stair Parameters: Observe: Grasshopper automatically produces Integer or Real sliders with according decimals based on your input: So let’s produce 5 Number Sliders via typing numbers (metric) on the GH canvas as shown. This relates to a massive concrete stair without landing, turns and railing. Input Parameters <Ī flight of stairs can be defined by 5 input parameters: Whereas my list looks straightforward, the middle part – constructing the points establishing the stair contour – is by far the biggest.

Produce the stairs as extrusion of this elevation.

Produce the according side elevation via points and polyline.

Define floor height, step count, gradient, slab thickness and flight width (input parameters).

To get aquainted with Grasshopper see this article.

I am well aware there are other and maybe better solutions.

The Parameters: Floor height, step count, gradient, slab thickness, flight width. While diving further into Rhino Grasshopper I set myself this task: Extrude a simple flight of stairs from its elevation.
