Data for: A view-based 3D CAD model reuse framework enabling product lifecycle reuse

CAD_MV80 is an engineering domain dataset that contains eighty 3D CAD models in eight categories, including gear pump, tube fittings, bearing pedestal, ring flange, locking assemblies, cutter arbor, piston pump, and hydraulic motor. In CAD_MV80, each 3D CAD model is represented as a collection of both solid views and line views captured from 26 fixed viewpoints, respectively. That is, there are 4160 views in CAD_MV80 (520 views in each category), and each view is a grayscale image with size 224×224. The reason for using 26 fixed viewpoints is that these viewpoints are commonly used in engineering drawings and could capture almost all spatial information of a 3D CAD model. CAD_MV80 provides the python version of the data, which could be easily used for machining learning.CAD_MV80是一款工程领域数据集，包含8个类别下共计80个三维计算机辅助设计（Computer-Aided Design，CAD）模型，涵盖齿轮泵、管接头、轴承座、环形法兰、锁紧组件、刀杆、柱塞泵以及液压马达。在CAD_MV80中，每个三维CAD模型均对应从26个固定视点采集的实体视图与线框视图集合。该数据集总计包含4160张视图（每类别对应520张视图），且每张视图均为分辨率224×224的灰度图像。选取26个固定视点的原因在于，这些视点为工程制图中的常用视角，可完整采集三维CAD模型的几乎全部空间信息。CAD_MV80提供Python格式的数据版本，可便捷应用于机器学习任务。
