Quick Measure is an interface tool that allows users to measure lengths and angles directly within the 3D viewport across different operating modes. It supports both temporary measurements and persistent saved measurements, enabling multiple data points to be placed and tracked simultaneously.

The tool features vertex and grid snapping, axis-restricted movement for precision, and the ability to lock measurement points to specific object vertices. Users can interact with saved measurements directly in the viewport to select, separate, join, or remove points as needed. It integrates fully with native Blender units.
