Include stackup height in track length 时，就会使用为每个网络类定义的布线宽度和过 孔尺寸。 这些宽度和尺寸被认为是该网络类的默认或最佳尺寸。 它们不是最小或最大值。 手动将布线宽度或过孔尺 寸改为与网络类部分定义的不同的值，不会导致违反 DRC。 要将布线宽度或过孔大小限制在特定的值，请使用自定 义规则。 网络类部分的下半部分列出了基于模式的网络类赋值。在 原理图编辑器文档 中解释了基于模式的网络类分配的工 作；基于模式的分配可以在 footprint or a selection of footprints, ignoring any connected track segments that are not selected.
