  • Why the same net via and shape can not connect togeter?

    I have met a problem when use 16.5 in divide power layer, the same net with the dynamic shape and via cannot connect together. just like pic as follow or link. The via avoid the shape. And I want to know how to solve it, thanks a lot! http://xiangce.baidu.com/picture/detail/8f2f80782f2eeecf44752e05fa10543a59b5931c

  • Manual entry of components

    Is there any way of manually adding a component to an Allegro PCB design using PCB Design XL in the same way that you could in OrCad Layout. I have been able to copy a footprint but the component is unassigned (R*) and I cannot find how to assign it a new part number and to connect nets to it. In Layout...
