基于零件实物样件的几何模型的反求已成为ＣＡＤ／ＣＡＭ领域中的一个研究热点。对目前国内外在复杂曲面产品反求工程中ＣＡＤ建模方面的研究现状做一较为简要的归纳。
The reverse of geometrical models based on physical parts of parts has become a research hotspot in CAD / CAM field. A brief summary of the current research status of CAD modeling in reverse engineering of complex curved surfaces at home and abroad is given.
