Loading the Dataset

from datasets import load_dataset

dataset = load_dataset(
    "YOUR_USERNAME/3d-cad-dataset",
    split="train"
)

print(dataset)

Restoring the Original Dataset

Each row stores the original binary content together with its original relative path. The dataset can therefore be reconstructed exactly as it existed before conversion by writing the content field back to the corresponding relative_path.

Intended AI Use Cases
