MACHIN3tools is a comprehensive and customizable suite of utilities designed to streamline modeling and scene management workflows in Blender. The add-on consolidates numerous operations into accessible pie menus covering modes, saving, shading, views, alignment, cursor placement, origin manipulation, snapping, and collections. It also features context-sensitive "smart" tools for handling vertices, edges, and faces, alongside dedicated functions for cleanup, mirroring, extrusion, grouping, and material selection. Advanced versions of the toolset include specialized capabilities such as edge constrained transforms, group gizmos and poses, and the Punch It tool.
