GeoMeasure is a geometry nodes-based measuring tool for Blender that allows users to capture real-time dimensions and distances of 3D models. It operates interactively, dynamically updating measurements as models are scaled, rotated, or edited. Users can generate custom rulers as cyclic or non-cyclic curves and place markers for spatial awareness. The tool includes several customization options for the display of measurements. Users can switch between millimeters, centimeters, meters, inches, and feet. Additional controls allow adjustments to text size, offset distances, and the application of dynamic color axes for X, Y, and Z dimensions.
