Summary
The CP_PLARC2PL command converts arc segments in polylines or ARC objects into polylines composed of linear interpolated segments. This transformation approximates the curved sections with straight lines, while keeping the original linear segments unchanged.

Key features include:
- Arc Interpolation Methods:
- Angular: Samples the arc at specified angular intervals (e.g., 5 or 10 degrees), generating linear segments at consistent angles. Ideal for applications where uniform angular sampling is needed.
- Chord Length: Limits the maximum chord length during arc interpolation, ensuring precise control over the length of straight-line approximations.
- Chord Perpendicular (Crown Distance): Defines the maximum allowable perpendicular distance from the midpoint of the chord to the arc, providing tight control over the accuracy of the arc approximation.
- Layer Placement Options:
- Source: Places the converted polylines in the original layer of the source object.
- Current: Places the converted polylines in the current active layer.
- Deletion Option: Optionally delete the original arc polylines or ARC objects after conversion to keep the drawing clean and organized.
The CP_PLARC2PL command is perfect for CAD professionals needing precise control over the conversion of curved geometries into linear segments, especially in scenarios requiring accurate representations of surveyed horizontal curves.
