What Are Node Dimensions?

Node Dimensions are ready-to-use, customizable measurement tools that add professional Distance, Radius, and Angle indicators to your Blender scenes using Geometry Nodes and Python.

Whether you're working on product designs, architectural models, or technical animations, these dimension overlays provide clear measurements without requiring manual setup.

With just a few clicks, add polished CAD-style annotations that remain editable, animatable, and automatically update with your geometry - saving time while enhancing your presentation.

The Story Behind the Product

As Geometry Nodes revolutionized Blender's procedural workflow, one gap remained: precision measurement tools.

This product fills that void by bringing accurate Distance, Radius, and Angle measurements into your workflow through Geometry Nodes and Python automation. It bridges creative design with technical precision, offering clean, animated dimensions that stay connected to your geometry.

Whether you're creating engineering visuals, architectural presentations, or simply need better spatial reference, Node Dimensions gives Blender the precision tools you've always wanted.

Three Geometry Node Dimension Tools

Includes specialized Distance, Radius, and Angle measurement systems built with Geometry Nodes. Each tool delivers precision and clarity for CAD-style annotations, technical visualizations, and procedural workflows.

Measure Distance

Create precise distance measurements between points with customizable arrows. Choose from 3 arrow styles and 6 units (mm, cm, m, inch, ft, yd). Ideal for technical annotations and scale references.

Simply select 2+ vertices in Edit Mode to generate measurements. The system automatically creates instances between each vertex pair (A,B,C becomes A-B and B-C). Closed shapes generate complete perimeter measurements (A,B,C,D becomes A-B, B-C, C-D, D-A).

Measure Radius

Instantly visualize radii for circular meshes or arc segments. Perfect for rounded geometry and curves in engineering models. Delivers clean, scalable measurements for CAD-style presentations.

Select 3 vertices in Edit Mode to generate Radius/Diameter measurements.

Measure Angle

Select any mesh, then choose 3 vertices in Object Mode (via cursor selection) to calculate angles.

Display angular relationships with clean arc visuals and precise values. Excellent for mechanical designs, rigging setups, or architectural plans. Snaps to vertices and updates dynamically.

Key Features

Animatable Dimensions
All measurements support animation with auto-keyframing. Perfect for demonstrating transformations, morphs, or technical animations.

Customizable Colors

Each dimension type has dedicated emission-based materials for easy color customization. Maintain visual organization in complex scenes.

Font Flexibility
Use any font or choose from built-in technical options (ISOCP & ISOCPEUR). Achieve authentic blueprint or CAD styling instantly.

Complete Control

Access all settings via popup panels or modifiers. Adjust units, font size, colors, labels and more without navigating node trees.

Smart Formatting

Supports comma decimals and additional text labels (e.g., "Length: 2.5m").

Automatic Updates
Dimensions stay locked to source vertices, updating in real-time with any transformation. Your original mesh remains untouched.

Scale-Friendly
Works perfectly with non-uniform scaling - no need to apply transforms.

Efficient Generation
All node setups are automatically created via Python - no manual node work required.

Enhanced Visibility

• One-click thick wireframe overlay
• Toggle between white and blueprint backgrounds
• Auto-contrasting text for optimal readability

Render Ready
Works flawlessly in both Cycles and Eevee. Performance-optimized with low-poly meshes and emission shaders.

Built with Geometry Nodes

All dimension visuals are created using Blender's Geometry Nodes, with Python automating the setup process.

About the Creator

Hi! I'm Vikrant Jadhav - motion graphics artist and creator behind Blender Renaissance.

My previous add-on "Node Charts: Info Graphs For Blender Using Geometry Nodes" has:

• Sold 150+ copies
• Earned eight 5-star ratings and one 4-star review

With over 10 years of professional Blender experience, I've created explainer videos and app promos for clients worldwide (US, Spain, India, New Zealand).

Why I Created This Tool

When I required technical measurements in Blender, no Python-based Geometry Nodes solution existed. So I built Node Dimensions to:

• Quickly add editable, precise markers (distance/radius/angle)
• Work entirely within Geometry Nodes
• Streamline my technical animation workflow

I believe it will revolutionize your workflow too.
