Node Dimensions is a suite of tools for adding CAD-style visual measurements to meshes in Blender. Built using Python and Geometry Nodes, it provides indicators for distance, radius, and angle. The distance tool can calculate lengths between selected vertices, the radius tool measures circular segments using three points, and the angle tool displays angular relationships between three selected vertices.

The generated dimension indicators are animatable, with values updating dynamically as the underlying geometry changes or is animated. The measurement overlays remain editable, featuring unit conversions across metric and imperial systems. The addon includes popup and modifier panels for configuring appearance, colors, font support, and styling elements like arrows and text labels.
