Assumptions & limits
Assumptions & limits
- User-selected area deduction convention; openings are nonoverlapping and lie within their parent wall, which user must verify. Net area nonnegative. Supported limits: All numeric inputs must be finite. Only the explicitly described mathematical scenario is supported.
