Hole Remover earns its place in the Superhive library by keeping its scope tight, circular through-holes only, and pairing detection with a preview step and an optional duplicate mode, so you can test a cleanup before committing to it.
Hole Remover targets a specific cleanup job in Blender: finding and removing circular through-holes in imported CAD meshes. Rather than acting as a generic fill-holes repair tool, it looks for CAD-style geometric features such as sharp circular rings, matching coaxial openings, and connected side-wall faces. Detected holes can be previewed before removal, and the process cuts polygon count for easier editing, faster rendering, and real-time 3D work. One example brings a mesh from 3126 down to 172 triangles.
The add-on works on one or multiple selected mesh objects and filters holes by maximum diameter, so you can limit removal to a chosen size. An optional duplicate mode preserves the original mesh, and the tool reports removed holes and topology changes. Work happens on the selection in Edit Mode.
Scope is deliberately narrow. Hole Remover handles circular through-holes and does not identify countersunk holes, blind holes, slots, or heavily distorted curved features. Removal can deform the mesh, especially on complex surfaces or when only some holes are cleared from the same area, so difficult CAD topology may need multiple attempts, adjusted settings, or the preview and duplicate options to test results safely.
Hole Remover - Clean Cad-Style Through-Holes From Imported Meshes is best for cAD mesh cleanup, hard-surface asset preparation, reducing unnecessary topology, lowering triangle count for real-time 3D assets, and cleaning mechanical parts before rendering.
Hole Remover - Clean Cad-Style Through-Holes From Imported Meshes is completely free to download and use.
Hole Remover lists compatibility with Blender versions 5.0 through 5.1 and is marked as Blender Extension compatible. It runs as an add-on and works on selected mesh objects in Edit Mode, targeting circular through-holes in imported CAD geometry. Because the supported range is specific, it's worth confirming your Blender build falls within 5.0 to 5.1 before installing. For any versions outside that range or the latest licensing details, check the developer's page.
Hole Remover installs from a downloaded .zip file. Open Blender, go to Edit then Preferences, choose Get Extensions, click Install from disk, and select the ZIP you downloaded. Once installed, the add-on operates on one or multiple selected mesh objects, letting you preview detected holes before removal and optionally keep the original mesh through its duplicate mode. Refer to the included documentation for further setup detail.
Hole Remover is focused on circular through-holes and does not identify countersunk holes, blind holes, slots, or heavily distorted curved features. If your CAD import relies on those shapes, they fall outside what the tool detects. It works best on sharp circular rings with matching coaxial openings and connected side-wall faces, which are the geometric features it searches for. For meshes with mixed hole types, expect to handle the non-circular ones by other means.
Hole Remover can deform the mesh during removal, particularly on complex surfaces or when only some holes are cleared from the same surface area. For difficult CAD topology, a clean result may take multiple attempts, adjusted settings, or use of the preview and duplicate options to test safely. The duplicate mode preserves the original mesh, so you can compare before and after without risking your source geometry. Reviewing detected holes in preview before committing also reduces surprises.
Hole Remover is listed as free in this catalog. Licensing and any support terms can change, so check the developer's page for the current arrangement before you rely on it. On the functional side, the add-on detects circular and near-circular through-holes, filters them by maximum diameter, and reports removed holes and topology changes so you can gauge how much geometry was affected during each cleanup.
