PIE2F-CAD

PIE2F-CAD is a structured parametric CAD dataset by Parergon for training and evaluating text-to-CAD systems.

It contains 100,000 aligned instruction and program records with construction sequences, geometry metadata, quality scores and fixed group-aware splits. A 5,000-record multimodal subset adds eight renders, STL meshes and STEP geometry.

Configurations

• cad_core: complete programs, instructions and structured CAD metadata.
• text_to_cad: compact instruction-to-program training pairs.
• cad_multimodal: programs and instructions paired with renders, STL and STEP assets.

Usage

from datasets import load_dataset

dataset = load_dataset(
    "Parergon/pie2f-cad",
    "text_to_cad",
    token=True,
)

Records are normalized, syntax-validated, deduplicated and assigned to deterministic group-aware splits.

The trajectory field represents the ordered construction calls in each program. It is not a desktop interaction recording or runtime trace.
