How to Fix non manifold vertices/edges


Fixing non-manifold vertices and edges is a crucial part of using the Mesh Cleaner in CATIA V5 Digitized Shape Editor. Here's a detailed guide:

Identifying Non-Manifold Issues:
Visual Inspection: Look for self-intersections, overlapping faces, or edges connected to more than two faces.
Analysis Tools: Use the Analyze Mesh tool to identify non-manifold vertices and edges specifically.
Fixing Non-Manifold Vertices:
Automatic Fixes: Often, the automatic cleaning mode effectively removes most non-manifold vertices.
Merge Vertices: This option combines close-proximity vertices, ensuring each vertex connects to exactly two edges.
Delete Isolated Vertices: Removes stray vertices not connected to any edges.
Fixing Non-Manifold Edges:
Automatic Fixes: Try running the cleaner with automatic fixes first.
Flip Edge Normal: This option reverses the direction of an edge if it's causing non-manifold issues.
Split Edge: Divides a problematic edge into smaller, well-defined segments.
Merge Edges: Combines neighboring edges if they overlap or form a sharp angle.
Delete Isolated Edges: Removes edges not connected to any faces.
Additional Tips:
Adjust Tolerances: Experimenting with different tolerance values in the Mesh Cleaner Options can offer better results in specific cases.
Combine Tools: Sometimes, a combination of different repair options is necessary to fix complex non-manifold issues.
Preview Changes: Use the preview function in the Mesh Cleaner Options to visualize the impact of specific repairs before committing them.
Review Results: After applying fixes, re-run the analyze mesh tool to ensure all non-manifold issues are resolved.
