CAD-SFT

Two subsets for supervised fine-tuning of CAD code-generation models.

Contents

cad-recode-20k (HF dataset config — loadable directly)

20,000 samples randomly drawn from filapro/cad-recode-v1.5 train split. Each CadQuery program is executed with cadquery, the resulting mesh is rendered into a single 4-view PNG, and both the code and the render are stored as a HuggingFace Dataset.

column	dtype	description
stem	string	batch_XX/N (upstream location)
code	string	raw CadQuery Python source
render_img	Image	4-view render of the executed mesh

Usage:

from datasets import load_dataset
ds = load_dataset("Hula0401/cad-sft", "cad-recode-20k", split="train")

text2cad/ (raw files)

Reformatted Text2CAD corpus — 171,177 CadQuery .py files re-laid-out from single-line compact form into multi-line chained result = (…) form for friendlier LM training. Content/geometry is unchanged.

text2cad/
  cadquery.tar.gz         # 171,177 .py files
  train.pkl               # 76,238 × {uid, description}
  val.pkl                 #  6,464 × {uid, description}
  test.pkl                #  8,035 × {uid, description}

Unpack: tar xf text2cad/cadquery.tar.gz. Each cadquery/{uid}.py is paired by uid with meshes/renders in Hula0401/deepcad_train_mesh.

Format difference, original vs. reformatted:

# Original (compact)
import cadquery as cq
w0=cq.Workplane('XY',origin=(-100,0,-14))
r=w0.sketch().face(w0.sketch().push([(100,0)]).circle(100)).finalize().extrude(28)

# Reformatted
import cadquery as cq

result = (
    cq.Workplane('XY', origin=(-100, 0, -14))
    .sketch()
    .face(
        cq.Workplane('XY', origin=(-100, 0, -14))
        .sketch()
        .push([(100, 0)])
        .circle(100)
    )
    .finalize()
    .extrude(28)
)
