Ortho2CAD Orthographic Drawings
This repository contains the orthographic drawings dataset from the paper Ortho2CAD: 3D CAD generation from orthographic drawings using vision language models.
- GitHub Repository: AdityaJoglekar/Ortho2CAD
- Paper: Ortho2CAD: 3D CAD generation from orthographic drawings using vision language models
Dataset Description
Ortho2CAD is a dataset designed to facilitate research in translating rasterized orthographic drawings directly into editable CadQuery code, which can then be compiled into 3D CAD models.
For detailed setup, drawing generation, training, and evaluation scripts, please refer to the official GitHub repository.
