第十一章管道的绘制使用PROE创建三维管道一般有三种方法：第一种方法、3维曲线扫描：先绘制一条曲线，然后再以这条曲线为中心线进行扫描成管道状的实体，这个零件的轨迹是空间的，所以不推荐使用扫描来实现。
第二种方法、“插入”高级特征：仅仅是个特征有一定的局限性，比如只能在零件模式下使用，装配模块是出不来管道实体的。
第三种方法、使用管道模块：功能强大优势明，工艺上，多数管道都是在各零件安装定位后安装，我们设计也是如此，因此管道（piping）只能在装配模式下才可以调用是明智的。
优点如下：（1）方便定义管理多种管线。
（2）布线方法多样、灵活、方便。
（3）方便提取管道信息。
（4）适合于管路复杂的装配设计。

图11-3 PNT0的定位图11-4 PNT1的定位图11-5 PNT2的定位图11-6 PNT3的定位图11-7 PNT4的定位图11-8 PNT5的定位图11-9 PNT6的定位七个基准点建立完毕。
步骤3：选择【插入】→【高级】→【管道】命令。
如图11-10。
图11-10 【管道】命令的选取弹出如图11-11菜单管理器图11-11选取管道命令后弹出的【菜单管理器】点击【完成】，在消息框里输入管道的外部直径25，如图11-12。
图11-12 输入外部直径接着输入侧壁厚度2，如图11-13。
图11-13 输入侧壁厚度在随后弹出的菜单管理器选择依次【单一半径】【整个阵列】【添加点】，如图11-14。
图11-14【连接类型】设置然后再依次选择基准点，顺序为PNT0→PNT1→PNT2→PNT3→PNT4→PNT5→PNT6。
