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.

I took a look at few of your videos. outstanding sir, have been doing Catia for more than two years but number of useful information i got only by looking as i said 2-3 your videos is what amaze me. Keep doing great job!

Thank you for your comment!!! Glad to help!

I got internal error. The current selected mesh is not available. You have to clean it before surface creation. I did every step here, please help 😢

[@3DComparison]

Send me the file and I will discuss the file on a future video in early july.

@@3DComparison thank you so much, wait

[@ulungprabowo]

Is it possible to send my file to your email and got you checked it and teach me how to fix it? Because every step I did and tried create another notification and problems which confuse me more.

[@3DComparison]

Yes, send the files to [e-mail] and I will make a video regarding this in the first week of July.

Thank you very much. But now I have another problem with the split connected zones. I have 41 connected zones, and if I fill the holes, it creates more connected zones. I would like to send you the picture of my problem via email, and I would be glad if you could help me.

Hello, you can send me the stl file at [e-mail] and I will look into it.
