CAD Generation Dataset
Each row in this dataset describes one parametric CAD part. Columns:
id— row identifier (also the basename of the per-row asset files)name— part family (e.g.flanges,spur_gear_stock)description— natural-language description of the geometrykey_parameters— the dimensions that drive the parametric modelimage— 512×512 PNG preview rendered from the FCStdfcstd_path— relative path inside this repo to the parametric FreeCAD document (fcstd/<id>.FCStd)viewer_url— full URL to an in-browser 3-D preview of the part on the viewer Space
The repo root also contains fcstd/<id>.FCStd, glb/<id>.glb, and
edges/<id>_edges.json for each row. The fcstd_path column points
into fcstd/; the viewer Space fetches GLB meshes and edge polylines
from glb/ and edges/.
Resolving fcstd_path
fcstd_path is a path relative to this dataset repo's root — for
example, fcstd/0603c53148.FCStd. Use huggingface_hub.hf_hub_download
to fetch one; it caches locally and handles auth for private repos:
from datasets import load_dataset
from huggingface_hub import hf_hub_download
ds = load_dataset("gnucleus-ai/cad-gen-freecad", split="train")
row = ds[0]
local_fcstd = hf_hub_download(
repo_id="gnucleus-ai/cad-gen-freecad",
repo_type="dataset",
filename=row["fcstd_path"],
)
print(local_fcstd) # local cached path, openable in FreeCAD
Or build a direct download URL if you want to share a link:
https://huggingface.co/datasets/gnucleus-ai/cad-gen-freecad/resolve/main/<fcstd_path>
Using viewer_url
viewer_url opens an interactive 3-D preview of the part:
<viewer-space-host>/?id=<id>
The HF Dataset Viewer renders this as plain text — it isn't clickable in the table. Copy the cell value into a new browser tab, or open it programmatically:
from datasets import load_dataset
ds = load_dataset("gnucleus-ai/cad-gen-freecad", split="train")
print(ds[0]["viewer_url"])
License
The dataset (parquet rows, PNG previews, GLB meshes, edges JSON, and the
FCStd files under fcstd/) is © gNucleus AI, Inc. and released under the
Apache License, Version 2.0.
The FCStd files are CAD geometry authored by gNucleus AI and saved via FreeCAD. As user data outputs of FreeCAD, they are not derivative works of FreeCAD itself, and FreeCAD's LGPL terms do not propagate to them.
Opening the FCStd files
Each fcstd/<id>.FCStd was authored with FreeCAD 0.21.2 and opens in any
FreeCAD 0.21+. FreeCAD is a separate open-source project (LGPL-2.1+) at
https://www.freecad.org/ — it is not bundled with this dataset. Most
readers will only need the parquet, PNG previews, and viewer Space; the
FCStd files are provided for users who want to edit the parametric source.
Validating model- or agent-generated FCStd files
If you've used a model or agent to generate a .FCStd from a row's
description and key_parameters, use the open-source
gNucleus-AI/freecad-validator
to score the generated file against the row's reference
fcstd/<id>.FCStd:
pip install gnucleus-freecad-validator
The validator reports geometry_similarity (solid count, volume,
surface area, bounding box, surface-type distribution),
cad_spec_consistency (named driven dimensions matching the part
spec within tolerance), and a harmonic-mean composite of the two.
See the repo README for the CLI and Python API.
