RealCADBench-V1.0

RealCADBench-V1.0 contains design-intent inputs and ground-truth STL shapes for evaluating AI CAD models and agents on parts and assemblies.

The test split is an evaluation collection, not a newly created train/test partition. The default all configuration combines every sample. The six other configurations provide the individual subsets without duplicating the Parquet files.

Category	Subset	Samples
part	text	568
part	2d_drawing	236
part	real_pic	568
part	real_pic_aug	10792
part	rendered_img	373
assm	assm	167
Total		12704

Preview fields

Field	Meaning
category	part or assm
subset	text, 2d_drawing, real_pic, real_pic_aug, rendered_img, or assm
input_text	Actual text input; empty string for image-only samples
input_images	Ordered list of input images embedded in Parquet
original_image	Original auxiliary image for text samples; null for other subsets
gt_shape	STL path relative to the repository root

original_image is auxiliary source material for the text subset, not an additional input to the text-only evaluation task. STL geometry is distributed as original files; the table displays the STL path.

Original files and mappings

• part/input/<subset>/ and part/ground_truth/<subset>/ contain part data.
• assm/input/ and assm/ground_truth/ contain assembly data.
• part/meta_info.<subset>.json and assm/meta_info.json are the canonical mappings.
• Paths in each original meta_info JSON are relative to that JSON’s directory. The preview gt_shape includes the part/ or assm/ prefix.
• Multiple images within a sample must be kept together. Different samples may share one GT, especially in 2d_drawing and rendered_img.

The release contains only files referenced by these mappings. Transfer archives, temporary files and audit reports are not part of the dataset payload.
