With the publication of the BRepNet code and occwl package, we now provide a full pipeline for reading STEP data and converting it to neural network input. I believe it will be easier for people to work with the data in STEP format using the BRepNet pipeline as an example. Hence version s2.0.0 of the dataset also has STEP files in it.
What?
The new version of the dataset is now available as s2.0.0.zip. The differences between the two datasets are as follows
178 designs from the original dataset could not be converted to STEP in a way which preserved the segmentation labels. These designs have been removed from all representations.
When reading the STEP data, so changes are present in the geometric entities and topology of the models. This should not effect most users of the dataset. The differences are documented here.
The folder breps now contains three sub-folders smt, step and seg. The segmentation labels for each face are in the seg folder. The order of faces in when reading the step data with Open Cascade and the Autodesk Shape Manager via the Fusion API is identical, so the same segmentation files are used.
The documentation is also updated. The s2.0.0 dataset is now the default option for download. A "Legacy versions" table is added in the segmentation dataset documentation to retain the link to the original version.
The documentation is updated to add a "Code" column to the main table. For the reconstruction dataset this points at the tools folder, while for the segmentation dataset I point at the BRepNet repository.
The segmentation dataset is updated to reflect the change to folder layout.
Additional links are added to guide users to the various visualization tools.
