AutoCAD中的'放样'在叉架类零件三维造型设计中的应用

摘要

The shape of fork parts is complex. The fork parts have multiple structures. Using AutoCAD software to do a three-dimensional model of the fork parts can be tedious since many high-level commands like " stretch" , " rotate" , " loft" , are to be used. Only if the correct method, drawing skills and techniques are mastered, the design can become simplistic. The design cycle and unnecessary duplication of effort can be reduced. Design ability and efficiency can be improved. This article takes an example of loft to describe the modeling AutoCAD lofting principles, methods and applications, expecting the better ideas.%叉架类零件形状复杂、结构各异.利用AutoCAD软件对其进行三维实体造型设计,设计思路比较复杂,并且造型中除用到基本的"拉伸"、"旋转"等命令外,还需用到"放样"等高级命令.只有掌握正确的绘图方法与技能、技巧,在设计中才能得心应手、应用自如,才可以缩短设计周期,减少不必要的重复劳动,提高设计水平和工作效率.为此,本文以支架为例介绍AutoCAD放样建模的原理、方法以及应用.
