🧱 CAD_dataset
Dataset Summary
CAD_dataset is a colletion of CAD operation data for language-driven parametric CAD modeling.
Each sample corresponds to a single operation in a CAD design process and includes:
- A natural language instruction
- The corresponding CadQuery code
- Rendered multi-view images of the resulting solid
The dataset enables training and evaluation of text-to-CAD, geometry reasoning, and multi-modal representation models.
Dataset Structure
| Field | Type | Description |
|---|---|---|
group_index |
string | Unique identifier, e.g. 00003_index_2/step0 |
instruction |
string | Natural language description of the modeling action |
geometry info |
string | The geometric and positional information of the operation |
code |
string | Corresponding CadQuery code |
single_image |
image (PNG) | Rendered image of the geometric shape of the operation, including both 3D shape and sketch |
full_image |
image (PNG) | Rendered visualization of the resulting solid model before and after the operation. |
Difficulty |
dict | Difficulty metrics of this operation, reflecting geometric complexity and modeling dependency level |
