CADGenBench Leaderboard

CADGenBench Leaderboard

Ranks AI systems that turn a text or image description of a mechanical part into a valid 3D CAD model, and scores uploaded STEP or BREP files. For CAD generation researchers and engineers.

About

What it is: CADGenBench Leaderboard is the results page for a benchmark of AI-driven CAD generation. It measures whether a system can read a written or pictured description of a machine part and return a 3D model that is valid and geometrically right.

The Space has three tabs. Leaderboard shows ranked submissions, Submit scores your own files, and About explains the scoring axes.

Who it suits: Researchers and engineers who build or compare systems that generate CAD models.

Industry | Who uses it | How they use it | Example
Mechanical engineering | CAD engineers | See how generation systems rank | Open the Leaderboard tab and read the rows
Research | AI researchers | Score their own model on the benchmark | Upload STEP files on the Submit tab
Software | Tool builders | Compare approaches to CAD generation | Read a submission's report

You can skip it if you do not work with CAD generation, since the Space only covers this benchmark.

Where to use it:

• A web browser, on the Space's page at Hugging Face, with nothing to install
• Windows, macOS or Linux with Docker, from a copy you download

Use case | Who | What they get back
Browse rankings | Researchers | A ranked list of submissions
Submit candidates | Model builders | A scored row with a per-submission report
Read the scoring | Anyone | An explanation of the scoring axes

How to set it up:

• Docker on your computer
• The huggingface_hub package, which gives you the hf command

1. Install the huggingface_hub package.
2. Download the Space with the hf command.
3. Move into the downloaded folder.
4. Build the Docker image.
5. Run the image with port 7860 open.

pip install -U huggingface_hub
hf download HuggingAI4Engineering/CADGenBench --repo-type space --local-dir CADGenBench
cd CADGenBench
docker build -t cadgenbench .
docker run -it -p 7860:7860 cadgenbench

How to use it: Open the Space's page in your browser. Read the Leaderboard tab for rankings. To submit, go to the Submit tab, upload your STEP or BREP candidate files and wait for the Space to run the evaluation.

Tool | What it does
Leaderboard tab | Shows ranked submissions
Submit tab | Takes STEP or BREP files and runs the evaluation
About tab | Explains the scoring axes and where the benchmark code lives

Example: You open the Submit tab and upload STEP files your system produced. The Space runs the evaluation and adds a row for your submission, with a report you can open.

For newcomers and experts: If you are new to CAD generation, start on the Leaderboard tab and read the top rows. Then open the About tab to see how scoring works.

If you know the field, the Space is a Docker app that serves several pages, including leaderboard, submit, gallery, metrics and admin views. It names two datasets, one for submissions and one for benchmark data. The repository also holds a tests folder and a tools folder.

You upload STEP or BREP files
The Space runs the evaluation
A row is published with a report
The row joins the leaderboard

Good to know:

• License: the Space lists apache-2
• Cost to run: none named
• Data it reaches: the files you upload, plus the two datasets it names
• Not for: scoring anything other than STEP or BREP candidate files
