CAD-Steps
A dataset of intermediate CAD construction states for training models on step-by-step geometry creation instead of final shapes only.
CAD-Steps is a dataset of intermediate CAD construction states. Not just finished models, but every step along the way, for training models on how geometry actually gets built.
Most CAD datasets only contain final shapes, so models trained on them learn what objects look like but not how a designer constructs them. CAD-Steps uses OpenCascade to replay construction sequences and capture each intermediate state.
The dataset is on Hugging Face and the generation code is on GitHub.
