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

Options

Option Description Default
Tolerance Maximum deviation from a perfect arc 1%
Minimum segments Minimum consecutive line segments to consider 4

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
