Hi, In PCB editor, the red X mean that net is not routed, you need add tracks, please check the bellow image. The top image is ratline, mean you need add tracks. the bottom image is done, so the red X gone. If this is not you need, please give us an screenshot of your designs ![enter image description here][1] [1]: /editor/20160104/5689eba3bb913.png

If you are seeing this problem in all the nets in a schematic, please check that the nets are wired using the **Wire** tool from the Wiring Tools palette (the `W` Hotkey) and that they are *not* drawn using the **Line** tool from the **Drawing Tools** palette. Please also check that the canvas attribute **Snap** is set to `Yes` in the right hand Properties panel and that you have red solder join dots at each 3 or 4 way wire junction.

I have a Vcc supply flag that always has a Red X in the Design Manager under Nets. I've tried everything from replacing it, to making sure that it is connected correctly with the wire tool as recommended, but it won't go away.

Hi, @Vamanose Red X means you don't connect two `pins` together, or it seem the pin is float VCC is net label, not a PIN. From the bellow image, the VCC net connect two pins, but the VDD is float, in this case you can add a NO connect flag to the pin. If this not your problem, do you mind to share an image with us? ![enter image description here][1] [1]: /editor/20160220/56c7db174760b.png

Make sure the nets of the connection wires\, pads\, and/or vias is the same\. i had same problem because my vias were net U\!\_11 and my wires were U1\_11 so i changed the ' \! " to a " 1 "\. hope that helps\.
