“元件轮廓”的实际用途是什么？

本教程需要:

DesignSpark PCB V11.0.0

DesignSpark PCB 在设计规则检查中使用元件轮廓来检查元件间距要求。

如果元件没有轮廓，它就使用丝网生成一个边界框形状来替代“元件轮廓”。

当没有为 DRC 定义轮廓时，上面讨论的方法在大多数情况下会生成“令人满意”的近似值。

如果您打算以某种角度（即不与 X、Y 轴对齐）定位任何元件，就应使用元件轮廓。原因是，所生成的用于替代轮廓的矩形边界框仍将与 X、Y 轴对齐，这将导致它比所需的面积更大。

另一种需要元件轮廓的元件是圆形元件，如径向电容器。当放置这种元件时，自动生成的边界框将是一个大的正方形，这会导致任何其他落入该正方形角落区域的元件报告错误。

因此，元件轮廓的用途是;

1.为元件提供一个精确的边界。
2.消除以某个角度放置元件时的错误
3.消除元件本身不是矩形时的错误。

I'm a Mechanical Engineer by qualification though I worked for a long time specialising in Motion Control systems and integration with various PLC systems. I've wide experience of many types of applications from packaging machines to military and some applications that I can't mention. At home, I like to tinker and make things with wood, metal, plastics, electronics and mechanical system. I'm never happier than with a hammer and a screwdriver in my hands....
