Close Holes tool settings panel
Close Holes detects open holes in your model’s surface and fills them to create a sealed, print-ready model.

​
When to use this

When your model has visible holes or gaps — common in models exported from sculpting software or game engines where surfaces aren’t always sealed.

​
Settings

​
Max perimeter (0–1000 mm)

Only close holes smaller than this perimeter. Default: 100 mm. Set higher to close larger openings.

​
Clearance offset (0–10 mm)

Add extra spacing around closed holes. Default: 0 mm.

​
Step by step

1

Select Close Holes

Click Close Holes in the toolbar.
2

Adjust max perimeter

Set how large a hole can be before it’s left open.
3

Run a repair

Hole closing is applied during the repair process.

​
Tips

  • Small holes (under 10 mm perimeter) are usually modeling artifacts — close them freely
  • Large holes may be intentional (like the bottom of a vase or a window opening). Set the max perimeter lower to preserve them.
  • Use the Errors tool to see how many holes exist before repair
