Check

This command reports errors in the data structure of selected objects, providing a detailed report on potential geometry issues. Steps to use:

1. Select the objects to analyze.

2. Review the generated report for identified issues.

3. If errors are found, consider deleting or remodeling the problematic objects.

• CheckNewObjects Detects errors in the data structure of objects as they are created or imported into the model. Details:

  • Displays messages in the command history when bad objects are created while opening or importing files.

  • If a problem is detected during modeling, undo, export the problematic object, and report the issue for debugging.

Diagnosing Common Issues

Detectable Issues and Solutions

1. Degenerate faces: Fix using the CullDegenerateMeshFaces command.

2. Zero-length edges: Often associated with degenerate faces. Use the same command as above.

3. Non-manifold edges: Identify with ExtractNonManifoldMeshEdges after removing degenerate faces.

4. Naked edges: These can cause issues in rapid prototyping. Fix using commands like FillMeshHole or MatchMeshEdge.

5. Duplicate faces: Remove duplicates with ExtractDuplicateMeshFaces.

6. Disjoint pieces: Separate unconnected pieces using SplitDisjointMesh.

Additional Issues and Best Practices

• Avoid creating curves with tiny segments or self-intersections.

• Ensure adjacent parts align cleanly with simple edge-to-edge matching.

• Repair faulty structures by breaking down objects (Explode), untrimming, re-trimming, and rejoining.
