对于汽车产品来说,分模的难点无非是在拐角的位置,只要能将拐角的位置处理的好,汽车模也算不了什么。那么下面我将分享一些汽车模分型面拐角位置的处理技巧。
1.将产品以X-Y平面放平,插入—派生曲线—抽取,选择产品,选择抽取轮廓曲线,将分型线抽出来
2.拐角处1的处理技巧
(1)错误的处理方式,直接以X轴拉伸出来的分型面有尖角
(2)正确的处理方式:先将坐标摆一个角度45°,然后以X轴拉伸,并用修减与延伸做拐角处理,做出来的分型面没有尖角
3.拐角处2的处理技巧
(1)先通过拉伸命令将两边分型面拉伸出来,留出拐角处2的位置
(2)桥接曲线,通过曲线做网格曲面,并约束面相切,做出来的面很光顺
4.拐角处3的处理技巧
(1)先通过拉伸命令将两边分型面拉伸出来,留出拐角处3的位置
(2)拐角处3较为平缓,可以用桥接曲面做出来,如图
5.拐角处4的处理技巧
(1)拐角处4跟拐角处1处理方式一样,如果直接拉伸会有尖角,必须先将坐标摆一个角度45°,然后以X轴拉伸
(2)用修减与延伸做拐角处理,最终得到分型面
