Bmesh Clean is a Blender add-on from Andrew_D that gathers common mesh cleanup steps into one automated pass. It targets models imported from software like SketchUp, handling the repetitive fixes so you can stay focused on design rather than mesh surgery.
With a single click you can execute a full cleanup sequence on a selected object or a group of objects, producing a clean, optimized mesh ready for shading and export. Individual operations are available too, including Limited Dissolve, Tris to Quads, Triangulate, Recalculate or Flip Normals, Delete Loose, Merge By Distance, and Shade Smooth with an Auto Smooth Angle for consistent shading across multiple objects. After each run, detailed results show what was modified so you can inspect the changes before exporting.
You can control all cleanup properties and save them as a preset on your computer, then reload it to reproduce the same pipeline across projects. Documentation links sit in each section of the add-on, so a right-click on the (?) icons opens the matching online docs. Bmesh Clean works with Blender 3.0 to 5.1 and is released under the GPL license.
