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
- Identifies polygons with inner contours (holes)
- Removes the hole from the parent polygon
- 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
