Stairs¶
In one sentence: Create a parametric stair flight with computed risers and treads from the storey height and user-specified dimensions.
Overview¶
Workbench: BIM
Menu: 3D/BIM → Stairs
Command: Arch_Stairs
IFC class: IfcStair
Creates a parametric stair flight. FreeCAD computes the number of risers and treads from the total rise height and user-specified step dimensions, following standard stair geometry rules.
