    A novel 3D CAD model retrieval method using 2D representative views is proposed for the reuse of CAD models. Initially, a set of 2D projected views is generated from multiple viewpoints which are evenly distributed on the viewing sphere of a CAD model. Then, the Apriori algorithm is employed to select the representative views from the set. The similarity between 3D models is determined by the like... View full abstract»
