Smart Trace Tolerance and Smoothing
Tune how the image region becomes a usable path.
On Trace, use Apply recommended settings as a starting point, then check the preview against the actual boundary. These settings improve contour extraction and output shape; they cannot restore missing source information.
Control the detected region
Color Tolerance controls which neighboring pixel colors are accepted in a region. Higher tolerance can join areas that should remain separate; lower tolerance can leave an incomplete region. Contrast Boost, Contour Type and Minimum feature area provide additional control over the trace.
Control shape detail
Simplification reduces contour complexity. Smoothing softens the contour. Increase them cautiously around corners and small details that need to remain accurate.
Compare and import
Changing settings can re-trace source-based paths. Inspect all affected results and any warning about oversized regions. On Import, check Fit quality, Maximum deviation, output segment count and Output as curves before adding the paths to the drawing.
