Topology Doctor earns its place in the Blender extensions library as a focused, single-purpose tool: it finds mesh topology flaws and puts them in front of you by selecting and zooming in, leaving the fix in your hands. At 16.5 KB it stays lightweight, and it targets Blender 4.2 LTS and newer.
Topology Doctor is a one-click topology analysis and fixing assistant for Blender, developed by Arman-Jangmiri. It inspects the topology of the selected mesh, tells you its flaws, then selects and zooms in on those flaws so you can fix them.
The add-on requests clipboard permission for a single task: copying the topology analysis report text to the clipboard. Version 1.0.0 was published on January 5th, 2026, the package is 16.5 KB, and it is compatible with Blender 4.2 LTS and newer. It is released under the GNU General Public License v3.0 or later.
Topology Doctor is available in the Blender extensions library and installs through Blender's extensions system, either by drag and drop or Install from Disk. The source and issue tracker are hosted on GitHub under the Arman-Jangmiri account.
Topology Doctor is best for blender users who want to inspect the topology of a selected mesh, see its flaws highlighted, and fix them by hand.
Topology Doctor is completely free to download and use.
Topology Doctor lists compatibility with Blender 4.2 LTS and newer, so current 4.2 installations and later releases are supported. Version 1.0.0 was published on January 5th, 2026, and the download comes in at 16.5 KB. It installs through Blender's extensions system, either by dragging the add-on into Blender or downloading the file and using Install from Disk. If you run an older Blender build, check the developer's page before installing, since the stated minimum is Blender 4.2 LTS.
Topology Doctor requests clipboard permission for one purpose: copying the topology analysis report text to the clipboard. After it inspects the selected mesh and identifies flaws, the report text can be placed on your clipboard so you can paste it elsewhere. This is the only permission the extension lists. For the full permission details and how the add-on handles the report, refer to the developer's page linked from the listing on GitHub.
Topology Doctor installs like other Blender extensions. You can drag and drop the add-on directly into Blender, or download the file and use Install from Disk through Blender's extensions preferences. The package is 16.5 KB, so the download is quick. Once installed, it works on the selected mesh, inspecting its topology, reporting flaws, and zooming in on them. Version 1.0.0 is the current release, published January 5th, 2026, and it requires Blender 4.2 LTS or newer.
Topology Doctor is released under the GNU General Public License v3.0 or later, and this catalog lists it as free. For current licensing terms and any changes, refer to the developer's page. The source and issue tracker are hosted on GitHub under the Arman-Jangmiri account, where you can review the code, report problems, and confirm the license that applies to your use. Version 1.0.0 was published on January 5th, 2026.
