MESHmachine is a toolset designed for hard surface mesh modeling in Blender, focusing on workflows that do not rely on subdivision surfaces. It introduces reconstructive modeling techniques, allowing users to modify or reverse existing geometry edits. Key features include the ability to turn chamfers into variable fillets, unbevel edges to restore hard angles, edit existing bevel widths, and resolve overlapping geometry where multiple bevels intersect.

The toolset also provides utilities for boolean operations and custom normals. Users can clean up applied booleans, generate clean perimeter loops, and manage geometry backups using a Stash system for normal transfers. Additionally, the Plugs feature allows for inserting detailed mesh components directly into surfaces, and includes tools for users to build and manage their own custom plug libraries.
