Assumptions & limits

Assumptions & limits

  • User-supplied measurements and assumptions; Sign schedule quantities multiplied by supplied support component counts; no wind-load or foundation design. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
