CAD Part Recommendation Dataset
This dataset is designed for CAD part recommendation.
assemblies.zip
Contains CAD assemblies across seven categories, with each category comprising at least 50 assemblies.assemblies_3-15.zip
Includes assemblies from assemblies.zip whose number of constituent parts ranges from 3 to 15. Each assembly not only contains the assembly itself but also its constituent parts along with their corresponding graph structures.
We represent each assembly as a graph, where vertices correspond to the constituent parts and edges indicate the contact relationships between parts, as illustrated in the figure below.
part_library.zip
Contains all the parts included in assemblies_3-15.zip.Partial Assemblies and Labels Generation
We employ Algorithm 2 to generate partial assemblies and their corresponding labels from the assemblies in assemblies_3-15.zip. These are used for the CAD part recommendation task.
Dataset Splits
The files train_dataset.json, test_dataset.json, and val_dataset.json store the training, testing, and validation sets, respectively.Each of these files contains the graph structures corresponding to the partial assemblies.
Using the graph structures together with the assemblies in assemblies_3-15.zip and the parts in thepart_library.zip, one can easily reconstruct the CAD models of the partial assemblies along with their corresponding labels.
Therefore, we do not include the CAD models of the partial assemblies in the dataset, as doing so would result in an excessively large dataset.
