Calculators / circulation

Stairs.
Geometry separated from local rules.

Use a verified regional helper where one exists, or enter project-defined geometry rules. Numevaro generates stair variants and material takeoffs without claiming legal compliance for a manual profile.

Stairs / stairwell

The rule profile is stored as a project snapshot. The verified Poland profile applies only to that market; other markets default to project-defined parameters.

3. Geometry variant

Variants are generated only from the active rule profile. A manual / project profile does not prove compliance with local regulations.
