CADroid

An advanced text-to-CAD engine that generates precise 3D CAD models from natural language descriptions.

Overview

CADroid is built on top of Text2CAD and extends its capabilities to provide:

• Enhanced text understanding for technical specifications
• Improved CAD generation with parametric design support
• Advanced quality validation and manufacturability checks
• Interactive parameter adjustment and real-time preview

Features

Core Functionality

• Text-to-CAD generation using state-of-the-art language models
• Support for complex CAD operations (extrude, boolean operations)
• Precise dimensional control
• Web interface using Gradio

Enhanced Text Understanding

• Advanced prompt engineering for technical specifications
• Support for engineering terminology and standards
• Dimensional constraint parsing
• Material specification handling

Improved CAD Generation

• Expanded primitive shape library
• Parametric design support
• Advanced constraint handling
• Enhanced precision control
• Assembly operations

Quality & Validation

• Real-time geometry validation
• Manufacturability analysis
• Dimension verification
• Material compatibility checks
• Cost estimation

Installation

# Create conda environment
conda env create -f environment.yml

# Activate environment
conda activate cadroid

# Install additional dependencies
pip install -r requirements.txt

Usage

Web Interface

cd App
python app.py

Command Line

# Generate CAD model from text
python generate.py --prompt "A rectangular prism with a cylindrical hole through the center"

# Generate with specific parameters
python generate.py --prompt "A 10cm x 5cm x 2cm rectangular plate with four 5mm diameter holes" --precision high
