本文报道了ＡｕｔｏＣＡＤ和３ＤＳ软件在实体模型制作中的应用。在构思、设计一件新产品的过程中，借助于计算机的几何造型功能，把产品划分为若干模块，分别制作各模块的实体造型，然后以积木块的形式堆砌在各自的位置上，执行布尔运算使各模块结合成为一整体。设计者可方便准确地把新产品设计转化成三维实体模型，缩短了实物模型的制作周期，提高模型的可靠性。 This paper reports the application of AutoCAD and 3DS software in solid model making. In the process of designing and designing a new product, with the help of the geometric modeling function of a computer, the product is divided into a number of modules, and the physical modeling of each module is made separately, and then piled up in their own position in the form of building blocks, The operation of the various modules together as a whole. Designers can easily and accurately convert new product designs into 3D solid models, shortening the production cycle of physical models and improving the reliability of the model.
