MeasureIt X

A modernized fork of the classic MeasureIt add-on for Blender, focused on a cleaner, more streamlined workflow and proper integration with the 3D viewport.

What's different in MeasureIt X

• Lives in 3D space, not screen space. Measurements are drawn as real 3D overlays, so they behave correctly with camera movement, perspective, and depth — no more flat, screen-glued labels that ignore your scene.
• Lean and focused UI. Panels and options have been simplified to keep the workflow fast and uncluttered. Less noise, more measuring.
• Built for Blender 5.x. Packaged as a modern Blender extension (blender_manifest.toml) and updated for the current API.
• Extra utilities. Includes a Sum Edge Lengths operator in the Edit Mesh > Edges menu for quickly totaling selected edge lengths.

Requirements

• Blender 5.0 or newer

Installation

Option 1 — Install from disk (recommended)

1. Download this repository as a ZIP (Code > Download ZIP) or clone it and zip the MeasureIt-X folder yourself.
2. In Blender, open Edit > Preferences > Add-ons.
3. Click the dropdown arrow in the top-right of the Add-ons panel and choose Install from Disk...
4. Select the ZIP file.
5. Enable MeasureIt X in the list.

Option 2 — Manual install

1. Copy the MeasureIt-X folder into your Blender add-ons directory:
   • Windows: %APPDATA%\Blender Foundation\Blender\<version>\scripts\addons\
   • macOS: ~/Library/Application Support/Blender/<version>/scripts/addons/
   • Linux: ~/.config/blender/<version>/scripts/addons/
2. Restart Blender.
3. Enable MeasureIt X in Preferences > Add-ons.

Usage

1. Open the N-panel in the 3D Viewport and find the View tab.
2. Select an object (or enter Edit Mode and pick vertices).
3. Use the MeasureIt X panel to add segments, angles, arcs, areas, labels, notes, or origins.
4. Measurements render directly in the viewport and follow your camera in true 3D.
5. For totaling edge lengths in Edit Mode: select edges, then Edge menu > Sum Edge Lengths.
