DXF2CAD

Overview

A generative AI framework that learns from 2D DXF blueprints to construct editable 3D CAD models in STEP format in seconds. This project represents a breakthrough in automated CAD model generation, significantly reducing the time and effort required to convert 2D technical drawings into fully functional 3D models.

Key Features

• Rapid Conversion: Generate 3D CAD models from 2D DXF files in seconds
• Editable Output: Produces fully editable STEP format CAD models
• AI-Powered Learning: Uses transformer-based models to understand blueprint patterns
• High Accuracy: Maintains geometric precision and design intent
• Industry Standard: Outputs in STEP format for universal CAD compatibility

Technical Architecture

The system employs a sophisticated multi-stage pipeline:

• DXF Parsing: Extracts geometric entities and relationships from 2D blueprints
• Feature Recognition: Identifies patterns, dimensions, and design constraints
• 3D Reconstruction: Uses transformer models to infer 3D geometry from 2D projections
• STEP Generation: Converts reconstructed geometry to industry-standard STEP format
