Face Angle Analyzer earns its spot in the Blender Extensions library as a compact, focused tool for reading face orientation, and it holds a 5.0 rating from a single review.
Face Angle Analyzer is a Blender add-on by Astralis for measuring and visualizing the orientation of faces against the global X, Y, and Z axes. Working in Edit Mode, it displays the angle from each global axis directly in the viewport using real-time 2D overlays, so orientation data appears alongside your geometry.
Beyond raw angle readouts, the add-on shows the Euler rotation angles needed to align a selected face with a chosen reference plane, and you can switch that reference between the X, Y, or Z axis. Visualization is interactive, with color-coded axes and angle arcs. You can toggle individual axes on or off, customize line thickness and arc radius, and recalculate multiple faces with a single click.
To use it, enter Edit Mode, select a face, open the FOA panel in the sidebar N-panel, and click Calculate & Visualize, changing the reference plane and recalculating as needed. It suits technical modeling, architectural work, and precise face alignment tasks, runs on Blender 4.2 LTS and newer, and is released under the GNU General Public License v3.0 or later.
Face Angle Analyzer is best for technical modeling, architectural work, and precise face alignment tasks in Blender.
Face Angle Analyzer is completely free to download and use.
Face Angle Analyzer lists compatibility with Blender 4.2 LTS and newer, so it runs on current 4.2 releases and later versions of the software. The add-on operates in Edit Mode, where you select a face and open the FOA panel in the sidebar N-panel to calculate and visualize its orientation angles. If you run a Blender build older than 4.2, you would need to update before installing. For the exact supported range and any newer builds, check the developer's page on Blender Extensions.
Face Angle Analyzer runs in Edit Mode: select a face, open the FOA panel in the sidebar N-panel, and click Calculate & Visualize to see the angle readouts. You can change the reference plane and click Recalculate as needed, and adjust visualization settings such as line thickness and arc radius to your preference. The add-on can be added by dragging and dropping the file into Blender, or by downloading and installing it from disk. Once installed, its panel appears in the 3D View sidebar.
Face Angle Analyzer is released under the GNU General Public License v3.0 or later, an open-source license. This catalog lists the add-on as free, and for current licensing terms tied to the GPL you can refer to the developer's page on Blender Extensions. The tool is developed by Astralis and is available at version 8.9.4. The GPL v3.0-or-later license generally governs how the code can be used, modified, and redistributed.
Face Angle Analyzer does not require special permissions, according to its Blender Extensions listing. It is a lightweight add-on at around 6.1 KB in size that operates within Blender's Edit Mode to measure and visualize face orientation angles. You can add it by dragging and dropping the extension into Blender or installing it from disk. For full details on requirements and permissions, check the developer's page.
