What it Does

Overrides default seam allowances on selected pattern edges with specialized measurements. The tool provides flexible options including preset defaults for common edge types or custom values for unique construction requirements, enabling precise control over individual pattern elements.

Select multiple lines or curves at once to apply the same seam allowance change efficiently across related pattern edges.

   • General Default: Standard allowance

   • Custom Value: Enter a specific measurement
