| # 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 the**part_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**. |
