Contextform - AI Design Memory Plugin for Rhino

Overview

Contextform captures your modeling process as intelligent "design memory" and uses AI to regenerate designs based on any criteria. Transform your designs by simply describing what you want: "make this organic", "optimize for 3D printing", "convert to sheet metal", etc.

The plugin understands not just what you modeled, but how and why - capturing relationships, dependencies, and design intent to generate contextually appropriate transformations.

✨ Key Features

🧠 Intelligent Memory Capture

• 50+ Supported Commands: Comprehensive coverage of Rhino modeling operations
• Semantic Understanding: Captures dimensions, positions, and design intent for each command
• Command Relationships: Tracks dependencies and workflow patterns between operations
• Transformation Tracking: Records precise movement, scaling, and rotation data

🔗 Workflow Intelligence

• Dependency Analysis: Understands which objects depend on others
• Workflow Stages: Distinguishes creation, modification, finishing, and analysis operations
• Pattern Recognition: Identifies common modeling workflows (creation sequences, modification chains, boolean operations)
• Design Intent: Infers the purpose and context of each modeling operation

🤖 Advanced AI Generation

• Context-Aware Scripts: Generates Python scripts that respect original design relationships
• RhinoScriptSyntax: Uses precise coordinate data and geometric properties
• Workflow Preservation: Maintains command dependencies during transformations
• Enhanced Prompts: Leverages rich memory data for more accurate generation

💻 User Experience

• Simple UI: Easy-to-use panel with intuitive start/stop capture
• Automatic Execution: Seamlessly replaces original geometry with AI-generated versions
• Rich Debugging: Comprehensive logging and analysis output
• Background Operation: Captures modeling process without interrupting workflow

🛠 Installation

1. Download the .yak file from Food4Rhino
2. Install using Rhino's Package Manager or drag-and-drop into Rhino
3. Restart Rhino
4. Find the Contextform panel in Panels menu

🚀 Usage

Basic Workflow

1. Start Capture: Click "Start Capture" and begin modeling
2. Create Geometry: Use any supported Rhino commands
3. Stop Capture: Click "Stop Capture" when finished
4. AI Transform: Enter a transformation prompt and click "Generate with AI"
5. View Result: Your original geometry will be replaced with the AI-generated version

🏗 Architecture

Memory Capture System

CommandCapture → MemoryManager → CommandDependencyManager
     ↓               ↓                    ↓
Semantic Data → Design Memory → Dependency Analysis

Data Structure

Each captured command includes:

• Semantic Data: Dimensions, positions, creation methods
• Relationships: Dependencies, workflow stage, command category
• Transformation Data: Movement vectors, scale factors, rotation angles
• Design Intent: Inferred purpose and context

AI Integration

• Enhanced Prompts: Utilize rich memory data for context-aware generation
• Workflow Awareness: Respect command dependencies and relationships
• Precision Execution: Use exact coordinate data for accurate reproduction

📋 Requirements

• Rhino 8 (Windows)
• Internet connection for AI generation
• .NET Framework 4.8 (included with Rhino)

🧪 Beta Version

This is a free beta version with full AI capabilities provided at no cost during the beta period. We're actively gathering feedback to improve the plugin's intelligence and capabilities.
