3）单击“直线”，选择“角度线、x轴夹角”输入角度55，输入定位点坐标（-65，-35），朝上作一根角度线，继续选择“角度线、y轴夹角”输入角度35，输入定位点坐标（65，-35），作另一根朝上的角度线与第一根角度线相交，如图2-3所示。 图2-3 图2-4 4）单击“整圆”，选择“圆心、半径”，分别以（-65，-35）和（65，-35）为圆心作半径为20和25的整圆，单击“曲线裁剪”删去多余线条如图2-4所示。 5）单击“曲线过渡”输入半径5，依次选择下面四个尖角将其倒圆角，然后输入半径10，倒上面尖角为r10的圆弧，结果如图2-5所示。 图2-5 图2-6 6）按f2退出草图，按f8以三维图形显示，单击“拉伸增料”，选择“固定深度”，输入深度为10，单击确定，结果如图2-6所示。 3.创建内轮廓 1）选择凸台上表面为“草图2”的平面基准，单击右键选择“创建草图”，进入草图模式，按f5用xoy显示。 2）点击“相关线”，选择“实体边界”，选择创建凸台的两条角度线草图，点击“等距线”选择“单根曲线、等距”输入距离10，分别将两条角度线朝下等距10。 3）点击“直线”，选择“水平/铅垂线、水平”，长度默认，输入放置坐标（0,0） 4）点击“平面镜像”，选择“拷贝”，分别选择水平线的一端与另一端为镜像轴的首点和末点，单击两条等距线，然后单击右键，结果如图3-4所示。 图3-4 5）点击“曲线过渡”，选择“圆弧过渡”，输入半径10，单击四边形相邻两条线，点击“删除”，删去多余线段，结果如图3-5所示。
