: Instead of drawing individual risers and treads, you can generate complex staircases from simple faces or planes almost instantly.

Visually, it manifests as a jagged, stress-fracture line running along the top nosing or the intersection point of the stair. It is the digital equivalent of a scar—a place where the math didn't quite add up, resulting in a "crack" in the surface topology.

It allows for precise control over riser height, tread depth, and total height.

The is a known glitch or geometric error that occurs when the software tries to calculate the intersection of a stair tread and a landing, or when a pre-cast concrete stair is manufactured with slightly misaligned tolerances.
