Auto-Constraints: Effortless 2D Constraints For 3D Tools

by in Addons

autoConstraints 1.3

autoConstraints is a Blender add-on designed to make working in 3D easier, faster and more intuitive.

It reduces the guesswork of working in the 3D viewport by automatically applying axis-constraints to a variety of 3D tools.

  • No need to manually apply constraints to every operation

  • No switching in and out of orthographic views

  • No clicking small parts of gizmos

Transform with the speed of Blender's gestural hotkeys and the accuracy of gizmos!

Easy to Learn

One toggle is all you need to start using autoConstraints.

There are no complicated hotkeys or menus to learn and if you have custom hotkeys, these will be respected. The add-on is designed to streamline your 3D workflows without getting in the way.

For full control over constraints, there is a dropdown with a minimal, easy-to-understand interface.


Tools will be constrained to the most appropriate plane based on the viewing angle, or you can specify a plane/individual axis.

Constraints can be still be overridden or cancelled interactively using default Blender methods, i.e. pressing axis keys, pressing 'C', or middle mouse dragging.

Customizable UI

Choose between a compact or expanded toolbar and whether it appears in the viewport header, the tool header, or not at all. The add-on sidebar is optional

Choose between grayscale planes, color planes, or original axis icons
