Blueprints is a Blender add-on from Blenderbob for managing background images used in modeling. It automatically sets up all views, and includes a swap-axis option that makes the X axis the front view.
You can also adjust all your background images at the same time. The add-on requires no special permissions, and it has been downloaded over 6,000 times from the blender_extensions library, where it currently sits at rank 498.
Blueprints is compatible with Blender 4.2 LTS and newer and is distributed under the GNU General Public License v3.0 or later. Version 1.0.3 brought code cleanup. A demo video is available, and the full source code is hosted on the developer's GitHub page, where the project has 11 stars. It was first published in May 2025.
