A developer known as machin3 has released a new tool that Blender Artists will definitely find useful. Meet PUNCHit, a dedicated, single-purpose add-on that features a negative manifold extrusion tool that attempts to work more reliably and be more flexible than Blender's native Manifold Extrusion. The add-on can be used to create a negative, manifold extrusion along either the averaged face normal, the individual vertex normals, or a user-defined edge.
Unlike Blender's native Extrusion tool, it can be used to punch through meshes, hence the name, as well as subtractively extrude at the mesh silhouette. The tool supports Windows, macOS, or Linux and is designed for Blender 3.0.
