Calculation method
Calculation method
Cut cross-sectional area (m²)
Integrate positive and negative piecewise-linear elevation difference separately, splitting sign changes.
Fill cross-sectional area (m²)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Common offset stations required; existing and proposed profiles linearly interpolated between them. 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. Common offset stations required; existing and proposed profiles linearly interpolated between them.
