Pro Measure earns a spot in the Superhive library for consolidating five measurement types and persistent multi-point measurements into a single Blender add-on.
Pro Measure brings dimensional measurement into the Blender viewport with real-time visual feedback. It offers five measurement types in one tool: object dimensions with color-coded X/Y/Z axis indicators, object bounds for multiple selected objects, distance measurement between object centers or custom points, a multi-point system for vertex-to-vertex, edge-to-edge, and face-to-face measurements, and area calculations for selected faces with polygon counts.
Smart measurement modes cover vertex snapping with intelligent highlighting and precision control, edge midpoint measurement with visual feedback, and face mode for distances between polygon centers. Advanced controls include complete metric and imperial unit support (from micrometers to kilometers, mils to miles), pinning objects to keep measurements visible after deselection, and management to organize, rename, and toggle visibility of individual measurements. Line thickness, colors, text size, and positioning are all customizable.
Version 1.1 adds persistent multi-point measurements: they are stored in the .blend file and survive save/reload, undo/redo, and object renames, so they are restored when you reopen a project. This addition was inspired by community feedback. Pro Measure is compatible with Blender 4.3 through 5.1.
Pro Measure is best for blender users working on technical modeling, architectural design, and quality control who need precise in-viewport measurements.
Pro Measure is completely free to download and use.
Pro Measure is compatible with Blender versions 4.3 through 5.1, and the developer notes it is fully tested and working with those releases. It is provided as a Blender add-on and is listed as a Blender extension. The listing also notes the render engines Cycles and Eevee. If you are running an older or newer Blender build, check the developer's page for the current supported range before installing.
Pro Measure stores multi-point measurements in the .blend file, so they are saved with your project and restored when you reopen it. These measurements also survive undo/redo and object renames. This persistent behavior was added in version 1.1 and was inspired by community feedback. Alongside it, the pin feature lets you keep measurements visible on objects even after they are deselected, so measurement data carries across save/reload, edit sessions, and object selections.
Pro Measure provides complete metric and imperial unit support, spanning from micrometers to kilometers on the metric side and mils to miles on the imperial side. It delivers real-time dimensional feedback directly in the viewport, showing object dimensions, distances, and area calculations with polygon counts. You can also customize how measurements appear, adjusting line thickness, colors, text size, and positioning to control the on-screen display of your measurement graphics.
Pro Measure is listed as free in this catalog. It is distributed under the GPL license and published by CreateVisions as a Blender add-on. Because licensing and pricing can change over time, check the developer's page for the current terms before you download or install. That page is also the best place to confirm the latest supported Blender versions and to view the available demo video for the tool.
