Hard Ops is a comprehensive modeling toolkit designed to streamline hard surface workflows and general interactions in Blender. It centralizes tools and operations into accessible menus, pie menus, and active tool systems, allowing users to minimize reliance on the default interface and maximize viewport space. The addon functions across object, edit, sculpt, and sketch modes, while also providing controls for lattices, curves, cameras, empties, and lights.

The toolkit emphasizes a non-destructive, modifier-based workflow. It includes systems for boolean cutting, interactive mirroring, and array generation using dedicated gizmos. Additional features include an interactive on-screen modifier dot system called hopsTool, modifier sorting mechanisms, and quick-access render configurations. The tool is built to condense complex operations into single button presses or localized popup menus.
