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.
