Pointer-CAD数据集
收藏资源简介:
Pointer-CAD数据集是由Transcengram联合多所高校构建的计算机辅助设计(CAD)模型数据集,包含57.5万个B-rep格式的模型。该数据集通过扩展OmniCAD基础数据,新增倒角、圆角等工业级操作指令,并采用多视角CAD渲染与Qwen2.5-VL模型自动生成高质量文本描述。其核心创新在于引入指针机制,将几何实体选择与命令序列相结合,显著降低了传统方法中的量化误差。该数据集主要应用于基于大语言模型的CAD生成研究,旨在解决复杂几何结构建模中的拓扑一致性和操作精度问题。
The Pointer-CAD dataset is a computer-aided design (CAD) model dataset constructed by Transcengram in collaboration with multiple universities, comprising 575,000 models in B-rep format. This dataset expands the basic data of OmniCAD, adds industrial-grade operation commands such as chamfers and fillets, and uses multi-view CAD rendering and the Qwen2.5-VL model to automatically generate high-quality text descriptions. Its core innovation is the introduction of a pointer mechanism that combines geometric entity selection with command sequences, significantly reducing the quantization error in traditional methods. This dataset is primarily used for large language model (LLM)-based CAD generation research, aiming to address the issues of topological consistency and operational accuracy in complex geometric structure modeling.
