AutoCad 教你绘制三爪卡盘模型,借用四视图来建模型小弟写教程纯粹表达的是建模思路,供初学者参考.任何物体的建摸都需要思路,只有思路多,模型也就水到渠成.ok废话就不说了.建议使用1024X768分辨率 开始先看下最终效果第一步,如图所示将窗口分为四个视图第二步,依次选择每个窗口,在分别输入各自己的视图第三步,建立ucs重新建立世界坐标体系,捕捉三点来确定各自的ucs如图第四步,初步大致建立基本模型.可以在主视图建立两个不同的圆,在用ext拉升,在用差集运算.如图:第五步:关键一步,在此的我思路是.先画出卡爪的基本投影,在把他进行面域,在进行拉升高度分别是10,20,30曾t形状.如图:第六步:画出螺栓的初步形状.如图第七步:利用ext拉升圆,在拉升内六边形.注意拉升六边行时方向与拉升圆的方向是相反的.之后在利用差集运算第八步:将所得内螺栓模型分别复制到卡爪上,在利用三个视图调到与卡爪的中心对称.效果如图红色的是螺栓,最后是差集第九步:阵列第10步.模型就完成了来一张利用矢量处理的图片
