Maximum horizontal swept reach (m)

Sample endpoints plus exact stationary angles of rectangle support extents over 0..opening angle.

Maximum vertical swept reach (m)

Sample endpoints plus exact stationary angles of rectangle support extents over 0..opening angle.

Prescribed hinge motion fits clear rectangle (1/0)

Sample endpoints plus exact stationary angles of rectangle support extents over 0..opening angle.

Assumptions & limits

Assumptions & limits

  • Zero-position panel horizontal; checks bounding clear rectangle about hinge, excludes localized obstacles, hinges and support strength. 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. Zero-position panel horizontal; checks bounding clear rectangle about hinge, excludes localized obstacles, hinges and support strength.
