CAD to Vision Model Pipeline

This document explains the end-to-end process of how WrenchML transforms your CAD files into training data for computer vision models.

Overview of the Pipeline

WrenchML's CAD to Vision Model Pipeline consists of several interconnected stages that work together to transform your static 3D models into rich synthetic datasets for training vision AI systems.

Stage 1: CAD File Conversion

Input Format

The pipeline begins with your CAD file in STEP format (.step or .stp). This industry-standard format preserves the precise geometry and design intent of your part.

Conversion Process

When you upload a STEP file, the system:

1. Validates the file to ensure it's properly formed and doesn't contain errors
2. Processes the geometry to optimize it for rendering
3. Converts the STEP file into GLB format, which is more suitable for real-time 3D visualization and manipulation
4. Preserves important geometric features and dimensions

Output Format

The result is a GLB file that:

• Maintains the precise geometry of your part
• Is optimized for fast loading and rendering
• Serves as the foundation for applying synthetic defects
