Quick Start

Installation: Install via Blender Extensions or manually place files in addons folder Activation: Press / (forward slash) or find iRuler panel in N-Panel sidebar Requirements: Blender 4.1.0 or newer

Core Features

Object Mode Measurements

• Distance Measurement: Select two objects to see real-time distance with ruler visualization
• Position Vectors: Shows vector from origin to object with magnitude display
• Displacement Tracking: Tracks object movement with delta vectors
• Component Analysis: Displays X, Y, Z components and vector projections

Edit Mode Analysis

• Vertex Information: Shows coordinates and distance from origin
• Edge Length: Displays edge measurements with visual indicators
• Face Analysis: Area calculations with normal vector visualization
• Selection Center: Calculates and displays center point of selected geometry

Automatic Unit Conversion

All measurements automatically convert when you change Blender's unit system:

• Metric Units: meters, centimeters, millimeters, kilometers
• Imperial Units: feet, inches, miles
• Custom Scale: Respects scene unit scale settings
• Smart Precision: Adjusts decimal places based on unit size

Interface Controls

Toggle Overlay: Press / or use the iRuler panel button Feature Selection: Enable/disable specific measurement types via checkboxes Real-time Updates: All measurements update automatically as you work

Panel Options

• Coordinate Axes display
• Position and displacement vectors
• Vector projections and components
• Distance rulers between objects
• Edit mode geometry analysis

Professional Features

Clean Display: Labels positioned at vector midpoints to reduce clutter Background Text: Semi-transparent backgrounds ensure text readability Element Limiting: Shows maximum 10 elements in edit mode to prevent overwhelming display Color Coding: Consistent color scheme - red/green/blue for X/Y/Z axes Performance Optimized: Minimal viewport impact with smart refresh system

Usage Tips

1. For Architectural Work: Enable distance measurement and coordinate display
2. For Precision Modeling: Use edit mode vertex analysis with displacement tracking
3. For Education: Show coordinate axes and vector components
4. For Quality Control: Compare object positions with component analysis
