Nova Arc stands out in the superhive library for putting radius measurement and segment-count guidance directly in the Blender viewport, aimed at low-poly and game-asset work.
Nova Arc is a Blender add-on for 3D artists who want clean, accurate circle shapes in their low-poly meshes. It measures distances precisely and shows recommended segment counts for rounded shapes right in the 3D viewport. While modeling, lines, arrows, and text recommendations appear directly on your selected elements.
The add-on provides real-time guidance on how many segments a given diameter needs for proper smoothness and definition. A QA mode compares current measurements against recommended values, making it quick to spot under-modeled geometry. Unit systems cover millimeters, centimeters, meters, and inches, with conversions handled automatically. Colors, fonts, line styles, and offsets in the overlay can all be adjusted.
Nova Arc runs on Blender 3.6 through 4.4 and supports the Blender-Internal, Cycles, and Eevee render engines. It's especially useful for low-poly modeling, game-ready models, and quality assurance. A demo video is available, and the add-on is released under the GPL license.
Nova Arc is best for low-poly modeling, game-ready models, and quality assurance checks in Blender.
Nova Arc is completely free to download and use.
Nova Arc runs on Blender versions 3.6 through 4.4, covering a wide span of recent releases. It works with the Blender-Internal, Cycles, and Eevee render engines, so it fits into most standard Blender setups. The add-on is released under the GPL license. If you're on a version outside that range, check the developer's page to confirm current compatibility before installing, since supported versions can change with updates.
Nova Arc lets you work in millimeters, centimeters, meters, or inches, and it handles all conversions automatically. That means you can switch units to match your project without recalculating measurements by hand. The measurements and recommended segment counts display directly in the 3D viewport as lines, arrows, and text on your selected elements, keeping the readouts in the unit system you've chosen while you model.
Nova Arc's QA mode compares your current measurements against the recommended values, making it quick to spot under-modeled geometry. Alongside this, the add-on suggests how many segments a given diameter needs for proper smoothness and definition, with that guidance appearing in real time in the viewport. This makes it particularly suited to quality assurance passes on low-poly modeling and game-ready models, where segment counts on rounded shapes matter.
Nova Arc is listed as free here in the catalog. Licensing and any pricing can change, so check the developer's page for the current terms before you download. The add-on is released under the GPL license. On the developer's side there are single-user and studio options covering different team sizes, so the right choice depends on how many people will be using it.
