 Spiral Stairs Linear Stairs is an element used for creation different circular staircases. It has the following parameters: "1.Inner Radius,(m)" - inner radius of spiral in the start (metres). "2.Height,(m)" - height of the staircase (metres). "3.Width,(m)" - width of a step (metres). "4.Number of turns:" - number of spiral turns (full-screw): it's possible set non-integer values too. "5.Quantity of stairs(1-50)" - quantity of stairs (integer). "6.Step base(m)" - inner depth of a step (metres). "7.Step height(m)" - height of a step (metres). "8.Step angle(deg)" - angle of a trapezoid step (degrees). "9.Ratio of Radius" - ratio of radius: start-radius to end-radius of the spiral (if the parameter is equal "1" the spiral has constant radius). Range of use: circular stairs, radial structures.
