PUNCHit is a Blender Extrusion addon featuring a flexible negative-manifold-extrusion tool, that is more robust and reliable compared to Blender's native Extrude Manifold.
It actually works.

PUNCHit 1.3 works with Blender 4.2 to 4.4!

Note: As of version 1.1, the PunchIt tool in MACHIN3tools DeusEx no longer has feature parity with this dedicated PUNCHit addon, and all future feature updates will only land here.

Features

• negative manifold extrusion, that works
  • punch into or through objects using single or multi-face selections

• dynamically pick from multiple extrusion directions:
  • averaged face normals
