Extract Holes

Converts polygon holes (inner contours) into separate, standalone polygons. This is the inverse of "De-embed."

When to Use

• When exporting to formats that don't support polygon holes
• To separate inner and outer contours for independent processing
• When downstream tools can't handle complex polygons with cutouts

Options

Option	Description	Default
Target layer	Layer for extracted hole polygons	Same layer
Selected layers only	Process only selected layers	Off

How It Works

1. Identifies polygons with inner contours (holes)
2. Removes the hole from the parent polygon
3. Creates a new polygon from the hole boundary on the target layer

Technical Notes

• The outer polygon becomes a simple polygon without holes
• Each extracted hole becomes an independent polygon
• Useful for GDSII export, which has no native hole representation
