Mesh Inspector is a diagnostic add-on that identifies topological characteristics and visually marks them on the mesh using vertex colors. It scans selected objects for specific geometric conditions, including triangles, n-gons, and various pole types (E-Poles, N-Poles, and poles with six or more edges). The tool also evaluates mesh curvature and analyzes face area consistency to highlight local density variations.

The analysis process is non-destructive, writing data to a dedicated "MeshDiagnosis" vertex color layer without modifying the underlying geometry or assigned materials. Operations are accessible from the 3D Viewport sidebar and can be accessed in both Edit Mode and Vertex Paint Mode. It is structured to handle quality control routines during subdivision surface preparation, rigging weight assignment, and export validation.
