What is a closed curve in XyzPilot?

A closed curve (CU-prefix) is a chain of connected lines and arcs that forms a closed loop. Used for defining CAM profiles.

Full Answer

A closed curve in XyzPilot is a chain of connected geometry entities (lines and arcs) that forms a closed loop. Closed curves are assigned CU-prefix labels (CU0, CU1…) and are used for defining CAM machining profiles.

XyzPilot uses backtracking chaining to build closed curves — it prioritises the operator-provided second entity and requires an actual closed loop before declaring success.

Closed curve chaining is certified for points, lines, and arcs. Circles and existing curves are rejected as unsupported chain members.

XyzPilot Example

Closed curve construction:
  L0, L1, L2, L3 form a rectangle
  A0, A1, A2, A3 are fillet arcs at corners

  Select entities in order to form closed loop
  → CU0: closed curve for CAM toolpath

CU labels are monotonic and immutable
  like all other entity labels in XyzPilot.
