Fill Hole Interactively

In one sentence: Click a hole boundary edge to fill that specific hole, giving precise control over which holes are closed.

Overview

Workbench: Mesh
Menu: Mesh → Meshes → Close Hole
Command: Mesh_FillInteractiveHole
Shortcut: none

Activates a pick mode where you click on a hole boundary edge to fill that specific hole. Gives more control than Fill Up Holes when the mesh has a mix of intentional openings and defect holes.

Intuition

Some meshes have intentional openings (the open base of a vase, the open end of a pipe) that should not be filled, while also having unintentional holes from scan defects. Fill Hole Interactively lets you choose exactly which holes to fill, leaving the intentional openings untouched.

When to use it

  • The mesh has a mix of intentional open boundaries and defect holes.
  • You want to fill only specific holes, not all open boundaries.
  • You need to verify each fill visually before confirming.

When NOT to use it

  • Don't use it when you want to fill all holes at once — use Fill Up Holes instead.

Step-by-step

  1. Select the mesh.
  2. Choose Mesh → Meshes → Close Hole.
  3. The open boundary edges are highlighted (red lines).
  4. Click on any edge that borders the hole you want to fill.
  5. The hole is filled immediately.
  6. Repeat for additional holes.
  7. Press Escape or click Close to exit.

Common mistakes and pitfalls

Fill is immediate — no undo prompt

Each click fills the hole immediately. If you fill a hole accidentally, use Ctrl+Z to undo before proceeding.

The fill uses flat fan triangulation

Like Fill Up Holes, the interactive fill produces a flat patch. Visually inspect the filled area and manually add triangles (Add Facet) if needed for curved surfaces.
