Don't Connect/Route Power Pin

Question

Hi everyone!

I'm making an Arduino Due Shield, and at the Main Board there are Output Power Pins (+5V, +3V3), which I use in my Shield.

The problem is that those pins are being connect one to each other (Output to Output) and not only to what is being used in my Shield (as Input).

Those Output Power Pins are in a simple Header.

Is there someway to tell the program to don't connect them?

Thanks!

I usually avoid replying on the CadSoft questions as they are usually more about CadSoft's protocols and not so much about the actual electronics. Here on the E14 site we see the CadSoft forum as but one of many streams. Based on the phrasing of the original question I stand by my answer but I can also see where I could have misunderstood the poster. John You are welcome. I think these old threads are a valuable source of informations for someone who will search for the solution to the same problem in the future. This thread might save someone hours of time. Especially because this thread is the very first result when searching google with the string: cadsoft eagle how to route not connected pins In fact I registered just to answer this question. Otherwise I use news client for accessing news.cadsoft.de server to read the topics but this thread did't show among the posts and I am not able to find it using any combination of the links starting from www.element14.com Regards

I have here described the solution. What original poster asked is legitimate demand and it seems the option of doing exactly what was asked was finally added as a new option in Eagle 7. No doubt Eagle developers added that option after realizing it was missing.
