Inward Extrude earns its place in the superhive library as a compact, single-purpose mesh tool: it builds on the established Extrude Pull and covers Blender 3.0 through 4.0 under the GPL license. The double-vertex cleanup is worth noting before committing it to a workflow.
Inward Extrude is a Blender addon from JMT Production for cutting into objects destructively, using the object's own geometry to make the cut.
In edit mode, select one or multiple faces and press Ctrl+Shift+E to cut into the mesh. The tool is also accessible from the Extrude Menu, reached with Alt+E. To perform the cut, the addon adds a cutter object slightly bigger than the selected face and runs a boolean operation. In some cases this can produce double vertices that need manual cleanup by merging them together.
The addon is built on Vladislav Kindushov and Martin Capitanio's Extrude Pull. It supports Blender versions 3.0 through 4.0 and is released under the GPL license. On superhive it holds a rating of 4 from six ratings, with over one hundred sales recorded.
Inward Extrude is best for blender artists who want to cut into meshes destructively using the geometry of one or more selected faces.
Inward Extrude is completely free to download and use.
Inward Extrude works in edit mode. Select one or multiple faces on your object, then press Ctrl+Shift+E to destructively cut into the mesh using the object's own geometry. You can also reach the tool from the Extrude Menu, which opens with Alt+E. Behind the operation, the addon adds a cutter object slightly bigger than the selected face and runs a boolean to carve the cut. Because of this, some cases can leave double vertices, so you may need to clean them up manually by merging them together afterwards.
Inward Extrude supports Blender versions 3.0, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6 and 4.0, covering a broad span of releases from the 3.x series up to 4.0. If you are running one of those versions, the addon is listed as compatible. For versions newer than 4.0, compatibility is not stated here, so it is worth checking the developer's page before installing to confirm the addon runs on your specific Blender build.
Inward Extrude performs its cut by adding a cutter object slightly bigger than the face you selected, then running a boolean operation to carve into the mesh. In some cases that boolean can produce double vertices. When this happens, the addon does not resolve them automatically, so the cleanup is manual: select the affected vertices and merge them together. This is noted as something that may occur in some cases, so a manual merge is the way to tidy the mesh afterwards.
Inward Extrude is listed as free here, and it is released under the GPL license. Licensing terms can change over time and may differ across the places the addon is distributed, so for the current cost and exact license details it is best to check the developer's page directly. The GPL license generally allows use and modification within its terms, and the addon page is the right place to confirm how it applies before you rely on it in a project.
