Stands out in the superhive library for narrowing to two edge operations — exact length and exact angle — reachable from the right-click context menu, rather than bundling a full CAD suite.
Set Exact Edge Length adds two operations to Blender's right-click context menu: setting an exact edge length and setting an exact angle. According to the developer, these are two simple, straight-to-the-point features accessed directly from the context menu.
The add-on came out of the developer's wish to handle these two tasks without learning a new workflow or installing a full CAD suite. It is aimed at precision modeling, CAD workflows, and architectural design, keeping its scope to those two edge operations.
It is a Blender extension-compatible add-on covering Blender 3.6 through 5.1, and it works with the Cycles and Eevee render engines. The plugin is released under the GPL license and ships with documentation. A demo video is available on the developer's page for a closer look.
Set Exact Edge Length is best for blender users doing precision modeling, CAD workflows, and architectural design who need to set exact edge lengths and angles.
Set Exact Edge Length is completely free to download and use.
Set Exact Edge Length lists compatibility with Blender versions 3.6 through 5.1, so it covers Blender 5.1 as well as several earlier releases in that range. It is marked as Blender extension-compatible and is distributed as an add-on. If you are running a version inside that range, the tool is intended to work with it. For versions outside 3.6 to 5.1, check the developer's page before installing to confirm current support.
Set Exact Edge Length is listed as working with the Cycles and Eevee render engines in Blender. The add-on focuses on setting exact edge lengths and angles from the right-click context menu, and its listing notes both engines as supported. If your project uses Cycles or Eevee, the add-on fits alongside that setup within the covered Blender versions from 3.6 through 5.1. Check the developer's page for any further details.
Set Exact Edge Length is listed as free in this catalog. Licensing terms can change, so check the developer's page for the current details before you rely on any particular arrangement. The add-on is released under the GPL license, which is noted on its listing. For the most up-to-date information on pricing and how it is distributed, the developer's own page is the best place to look.
Set Exact Edge Length places its two operations directly in Blender's right-click context menu: one for setting an exact edge length and one for setting an exact angle. Both are accessed straight from that context menu rather than through a dedicated CAD suite, matching the developer's aim of keeping them simple and straight-to-the-point. The add-on also ships with documentation, so the developer's page is the place to check for step-by-step guidance on using each function.
