SolidWorks基础命令图文教程-拉伸
SolidWorks拉伸命令图文教程实例模型如下http://www.ugsnx.com/data/attachment/forum/201606/29/105633rafwnhg00ghh4wwh.png
SolidWorks中绘制的模型如下http://www.ugsnx.com/data/attachment/forum/201606/29/105655z266r4bcc0tdr26t.png
用到的命令如下http://www.ugsnx.com/data/attachment/forum/201606/29/105728obqd892ez898drbv.png该实例只需3步拉伸就能完成，接下来就是绘制的流程。http://www.ugsnx.com/data/attachment/forum/201606/29/105741qpap8jrmjyx8x9x8.png新建零件-点击确定http://www.ugsnx.com/data/attachment/forum/201606/29/105753brtxtqgqgncck8c3.png选择软件窗口左上方草图模块下的-草图绘制http://www.ugsnx.com/data/attachment/forum/201606/29/105801nbdzok9x1v9gmmvw.png选择一个基准面，我选择的是右视基准面http://www.ugsnx.com/data/attachment/forum/201606/29/105809k3d34ns3bb1zdp4c.png选择直线命令绘制如下草图http://www.ugsnx.com/data/attachment/forum/201606/29/105816g13fgctj2uj2jj7t.pnghttp://www.ugsnx.com/data/attachment/forum/201606/29/105826xlllphsyoksplyap.png选择圆角命令http://www.ugsnx.com/data/attachment/forum/201606/29/105836a112o22d231n3svw.png将参数改为5，我们需要倒5mm的圆角。http://www.ugsnx.com/data/attachment/forum/201606/29/105846ki6hh7gzsi1i0dj8.png倒完圆角如上图所示http://www.ugsnx.com/data/attachment/forum/201606/29/105857ntir5xi5jx5i3r33.png点击智能尺寸http://www.ugsnx.com/data/attachment/forum/201606/29/105905ji6w6jorn76n336i.png对草图进行如上图所示约束。打开智能尺寸后，点击草图中的点或者线就能完成你想要约束的尺寸。http://www.ugsnx.com/data/attachment/forum/201606/29/105917m7mhxhchv8lxcvxt.png软件窗口右下角出现完全定义，表示草图已经完全约束，否则这里会显示欠定义。被约束后的直线颜色变黑，否则直线颜色是蓝色的。http://www.ugsnx.com/data/attachment/forum/201606/29/105928nilh3epz71llhieh.png然后直接切换到特征模块下，旋转拉伸凸台/集体，会出现如下图所示参数设置框。http://www.ugsnx.com/data/attachment/forum/201606/29/105936g6ljw9l93sksfe1h.png将拉伸深度改为105mmhttp://www.ugsnx.com/data/attachment/forum/201606/29/110021cgj52c9ahaiil3i2.png第一步拉伸完成接下来用同样的方法绘制草图拉伸，绘制基准选择第一个拉伸实体的底面。如下图所示http://www.ugsnx.com/data/attachment/forum/201606/29/110036kl8pm1ypyk8j8ldl.png点击下图选项切换视图http://www.ugsnx.com/data/attachment/forum/201606/29/110312tbbybqyytbo3y21y.png绘制如下草图http://www.ugsnx.com/data/attachment/forum/201606/29/110332qdzktz86ud3dsxd4.pnghttp://www.ugsnx.com/data/attachment/forum/201606/29/110332i5bbdc0zic5nqbau.png然后使用剪裁实体命令修剪http://www.ugsnx.com/data/attachment/forum/201606/29/110332qq4rdy6fcuydz4dc.png按住鼠标左键不放，划过上图红线所示路径完成草图剪裁。剪裁后草图如下图所示。http://www.ugsnx.com/data/attachment/forum/201606/29/110332n8qab1814ecebc38.png然后同第一个拉伸一样完成该草图拉伸。下图红框按键可以切换拉伸方向，同时将拉伸深度改为62mm。
