A problem I encountered a long time ago was that a circuit board was not fully coated with copper, only a small part of it was coated, but other places where copper was not coated were still connected to GND, and then I directly used Track to connect the uncoated Object to the The GND is covered with copper, but after the copper is re-applied, it is found that the copper and the connection are disconnected, because the rules stipulate the distance between Track and Poly:
you can see that the rules stipulate that the distance between Track and Poly is 0.2mm, so after Repour Polygon The following phenomena will occur:
We can create a new rule under Clearence, name it Clearance_PolyGND, and then set Where The First Object Mathces as Net-GND, and Where The second object Matches as Net-GND, which means that the target objects to which this rule applies are selected as GND network, and then set the Minimum Clearance to -0.1mm. If it is set to 0mm, there will be a little gap after re-applying copper. After setting it to a negative number, re-applying copper will completely connect, but the absolute value of this negative number cannot be too large, you You can try. The settings are as follows:
Re-apply copper after setting:
It can be seen that the copper-applied and the track on the right are completely connected together and have "extended" a little. The length of this "extended" is |-0.1|mm, isn't it very Amazing, the original AD rules can still be used like this! In fact, this is the simplest usage. AD rules can also use Query to find matches. Like scripts, it is very powerful! ! !
