Assumptions & limits

Assumptions & limits

  • Assumes uniform sampled density; no avalanche or roof-load conclusion. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints. Assumes uniform sampled density; no avalanche or roof-load conclusion.
