Single Flight Straight Stair Procedural MCG Tool for 3ds max 2023-2027

SingleFlightStraightStair — Version 2.2.4

SingleFlightStraightStair procedural MCG object is a powerful parametric stair generator for Autodesk 3ds Max, built to create accurate, production-ready straight staircases in seconds. Choose from Open, Closed, Box, Stepped, and Stepped Offset structures, then precisely control dimensions, slab thickness, tread nosing, extrusion segments, mapping coordinates, and more—all through an intuitive procedural workflow.

Design faster, revise effortlessly, and generate clean, fully capped geometry ready for architectural visualization and detailed 3D production.
