Dimensions and lines addon for Blender

Dimensions and Lines – CAD-Style Dimensioning & Technical Drawings for Blender

Dimensions and Lines is a Blender addon that enables the creation of dimensions, technical drawings, and blueprint-style layouts directly inside Blender.
It brings CAD-like dimensioning workflows into the 3D viewport while keeping all generated geometry fully renderable and non-destructive.

Key Features

📐 CAD-Style Dimension Creation

Create dimensions interactively with the mouse, using workflows similar to traditional CAD applications.
Dimensions update in real time and remain consistent with scene changes.

📏 Non-Destructive Mesh Lines

Generate construction lines from existing edges as real mesh geometry, without modifying the original model.
All lines and dimensions can be rendered like standard Blender objects.

🎯 Dedicated Snapping System

Dimension creation uses its own snapping system, allowing precise snapping to line centers and generated geometry for accurate technical drawings.

📄 Camera Setup for Technical Drawings

Configure cameras for specific paper sizes with correct render resolution based on selected DPI, making it easy to produce print-ready technical layouts.

🧱 Line and Hatch Types

Create multiple line styles and hatch patterns, suitable for sections, schematic views, and blueprint-style drawings.
