Req2CAD: Bridging Functional Requirements and Parametric CAD Models to Support Conceptual 3D Design
📌 Dataset Summary
The Req2CAD dataset is constructed on top of the Text2CAD dataset, which itself extends DeepCAD with textual annotations and rendered images. Building upon these resources, Req2CAD further enriches each CAD component with functional annotations, establishing a direct mapping between functional requirements and structural design representations.
Each sample contains the following core fields:
- uid: Unique identifier, consistent with DeepCAD and Text2CAD
- function_description: Natural language descriptions of CAD component functions
- function_keywords: Structured function labels in the form of verb + object, extracted from function descriptions
The function descriptions are generated by a VLM, Qwen2.5-VL-7B-Instruct, based on the input multi-view rendered images of CAD components, and the function keywords are extracted from the function descriptions by an LLM, Qwen3-14B.
The multi-view rendered images of CAD components can be downloaded from the Text2CAD dataset, and the parametric CAD representations and construction sequences can be downloaded from the DeepCAD dataset.
