Detect Arc Segments

Identifies polyline segments that approximate circular arcs without modifying them.

When to Use

  • To preview which segments would be converted by Convert Quasi-Arcs
  • For analysis and quality assessment of imported geometry
  • To verify arc approximation quality before conversion

How It Works

Scans all polylines and highlights segments that match arc criteria, without modifying the geometry. Results are shown in the viewer and status panel.

Technical Notes

  • This is a read-only analysis tool — no geometry is modified
  • Use this to decide whether to run Convert Quasi-Arcs
