Reply To: How do I fix this irregular face meshing problem?

Hi,

The blue status icon that may appear in the Tree Outline indicates that a mapped mesh cannot be provided on the scoped topology. This icon is triggered under one of three scenarios: the face cannot be map meshed, the quality of the mapped mesh was not acceptable and a free mesh was generated, or if the ‘Constrain Boundary’ is set to ‘Yes’ [Notes on Face Meshing Controls for Mapped Meshing]

To address the issue, you might want to check if the geometry looks problematic, especially if there are very sharp or thin faces, or if the graphics appear corrupted. You can try several options to resolve meshing problems: Troubleshooting

1. Add local size controls to reduce mesh size or modify defeaturing tolerance.
2. Merge faces locally using Virtual Topology.
3. Add a local Pinch control.
4. Modify the geometry in the problematic location using a geometry tool.
5. If the edges attached to the problematic face may be causing issues, inspect them for problems.
