Using the Polystair - advanced shapes

Using the Polystair functionality of the Stairs Tool, you can create highly custom stair designs that feature straight and curved stair shapes.

To use the Polystair functionality, make sure you set up your Stair Settings first (refer to the article Place a basic Stair using the Polystair if you are unsure), then:

1. Click on your plan view to start drawing your stairs:

TIP: Take a moment to view the options available to you. In the image above you can see the Polystair Origin (item #1); Polystair Reference Line (item #2); cursor position (item #3); Flight Preview (item #4); Tracker (item #5); and the Stair Placement 'Pet Palette' (item #6).


2. Choose the geometry of this leg of your stairs from the Pet Palette (you'll need to choose a Leg Geometry option and Run Type option):

Zone 1 (above) shows Leg Geometry options

  • Straight Edge
  • Curved edge starting at a tangent to the previous edge (not possible to start with this)
  • Curved edge starting at a tangent to a defined vector
  • Curved edge by three points
  • Curved edge by centre point

Zone 2 shows Run Type: Flight or Landing


3. After selecting your Leg Geometry (ie straight or curved), click again on the plan to place it

4. Return to the Pet Palette to choose another Leg or Run Type 

5. Click on your plan again to place the next Flight or Landing.

TIP: If you make a mistake you can press Backspace to undo the last step:

If you want to cancel the design, press your Esc key:

Continue adding Flights and Landings as desired.
