Gear Design Dataset

Dataset Overview

The Gear Design Dataset contains structured data that includes gear design specifications and their corresponding DXF (Drawing Exchange Format) files. The dataset is intended for training and evaluating machine learning models focused on generative design and CAD (Computer-Aided Design) tasks. The dataset is split into three parts: training, validation, and test sets.

Each entry in the dataset represents a specific gear type and includes:

• A dictionary of design specifications (the prompt).
• A corresponding DXF content (representing the 2D drawing of the gear).

The dataset is designed to support the development of generative models that can produce CAD designs from textual descriptions.

Data Splits

• Train: The training set contains a variety of gear types with their corresponding prompts and DXF content.
• Validation: The validation set is used for model evaluation during training.
• Test: The test set is used to assess model performance after training.

Dataset Structure

The dataset contains the following fields:

• gear_type: The type of gear (e.g., spur gear, bevel gear).
• split: The dataset split, which can be "train", "val", or "test".
• prompt: A dictionary of gear design specifications, including properties like number of teeth, material, pressure angle, and more.
• dxf_content: The corresponding DXF file content in string format.
