-	StairDesigner is a polyvalent straight, helicoidal, and balanced stair design software, used in the wood, marble, stone, and metal industries. StairDesigner allows a quick stairway parameters entry. Its Help and Control Function checks the Riser Height, Tread Length, and Stair Rule parameters (Blondel’s law), and helps reaching the stair compliance.
-
StairDesigner is based on the Boole & Partners exclusive Global Balancing Function, which summarizes major balancing theories, and calculates «S-shaped» stairs, cut-off corners stairs, English styled stairs, and rounded stairs, and also optimizes concrete stairs coverage (StairDesigner-Pro_RB). StairDesigner calculates all the stair components : steps, risers, stringboards, racks, straws, poles, handrails and banisters, which may be printed, plotted in a scale 1/1 (jigs), or exported in DXF format. The StairDesigner 3D integrated function (colors, textures, and transparency levels) displays the stair in various 3D views.

StairDesigner controls each of the Riser Height, the Tread Length, and the Stair Rule vis-a-vis [Min - Max] intervals.

When the stair values comply with the [Min - Max] control intervals (default values as per contra), StairDesigner displays a green signal.

Once the stairway is defined, StairDesigner calculates a stair global balancing. All steps are balanced by default, but each step’s postion may be moved individually: StairDesigner will then automatically recalculate the stair balancing.

"S shaped" Stairs:

StairDesigner is able to design up to 7 flights stairs. Each flight is determined by its dimensions, and its angle with the previous flight.

StairDesigner flights may be defined with an either left or right rotation, enabling "S-shaped" stairs design.

English style Stairs :

In the case of an "English style stair" (without stringboards), StairDesigner calculates the banisters positions directly in the steps.

StairDesigner takes into account the front and rear distances to the step nose, as well as the maximum empty space between two banisters, in order to reach the most homogeneous distribution

3D Function:

As a complement to StairDesigner’s built-in 3D function, with its predefined 3D views, and its zoom and rotation tools, the StairDesigner’s DXF 3D_Face export function is compatible with most CAD software.

Rounded Stairs: When successive flights are joined with arcs, StairDesigner calculates all the corresponding rounded shapes. This StairDesigner feature enables winding stairs design.
