Repair

Repair fixes common problems in mesh geometry, including non-manifold edges, holes, inconsistent face orientation, and nearly-coincident vertices. This is especially useful for imported STL and OBJ files that may have errors.

How to Use

  1. Select an object with mesh problems
  2. Apply the Repair operation from the Mesh menu
  3. Review the before/after statistics to see what was fixed

Statistics (Read Only)

  • Initial Vertices / Final Vertices - Vertex count before and after repair
  • Initial Faces / Final Faces - Face count before and after repair
  • Initial Non-Manifold Edges / Final Non-Manifold Edges - Problem edge count before and after

Advanced Options

Enable Advanced mode for fine-grained control:

  • Weld Vertices - Merge nearly-coincident vertices (default: on)
  • Weld Tolerance - How close vertices must be to merge
  • Face Orientation - Make all faces consistently oriented
  • Weld Edges - Repair small cracks and bad seams
  • Fill Holes - Fill gaps in the mesh surface
  • Remove Mode - Remove internal or occluded geometry:
    • None - Keep all geometry
    • Interior - Remove internal bodies hidden inside the main shape
    • Occluded - Remove faces blocked from outside view

Tips

  • Try Repair first if boolean operations (Combine, Subtract) produce unexpected results on imported models
  • The default settings (Weld Vertices on, everything else off) fix the most common issues
  • Enable Fill Holes if you can see through gaps in the model
  • Use Remove Interior to clean up models that have hidden geometry inside
