Summary

The GT_PLARC2PL command in GeoTools converts arc segments within polylines or ARC objects into polylines with linear interpolated segments, maintaining accurate representation in BricsCAD, AutoCAD, ZWCAD and ARES Commander.

Convert Arc Polylines to Linear Segment Polyline: GT_PLARC2PL – GeoTools Command

Key Features Include:

• Three Arc Approximation Methods:
  • Angular Interval – Converts arcs into linear segments at specified angular intervals (degrees). Ideal for geometric replacements at fixed angles.
  • Chord Length – Approximates the arc using line segments with a maximum chord length, ensuring controlled segment density.
  • Chord Perpendicular (Crown Distance) – Limits the maximum deviation from the arc to the chord midpoint, providing the most precise arc interpolation for survey and engineering applications.
• Layer Placement Control:
  • Source Layer – Places the converted polyline in the original object’s layer.
  • Current Layer – Places the converted polyline in the active layer.
• Option to Delete Original Objects:
  • Choose to remove the source arc/polyline after conversion for a cleaner workspace.

Use Cases:

• Topographical mapping & surveying where polyline arcs must be represented as straight-line segments.
• CNC machining & digital fabrication where linearized polylines are required.
• Road alignments & infrastructure planning needing accurate arc approximations.

Benefits:

This tool is essential for engineers, surveyors, and CAD professionals who require precision in converting arcs into straight-line segments while retaining geometric accuracy.
