Icepak中优先级的释义

在Icepak中建模时有选项可以设置模型的优先级，但是对优先级设置到底有何作用呢？下面以一个简单例子示意其含义。
在这个例子中，有两个Block，左下角的为Block1。从模型树中可以看到Block2的优先级较高。



下面看看网格划分后的结果：





从上面两图片可以看出Block1在叠加区域被“挖空”了，而优先级较高的Block2则保留了完整的外形。优先级的作用
上面的例子很清楚地解释了优先级设置产生的结果，在帮助手册中对Priority的描述为：
By default, objects are meshed in the order in which they were created. If two or more objects intersect, meshing the objects in the creation order may not give the result that you want. For such cases, you can modify the meshing order by changing the object priorities for the intersecting objects. The object with a higher priority (higher number) will retain the mesh where it intersects with an object with a lower priority.优先级的设置
可将模型显示的顺序设置为按优先级排列：Tree --> Sort --> Meshing Priority
