Cannot figure out how to correct this problem

I've used the help prompt that pops up with this error, and i cannot figure out how to do either of the solutions. Solution one, Change the schematic symbol. Using PinMap function. Change the PCB PIN from C to K. And save your schematic again. Solution Two, Modify the Footprint. Edit the Footprint, change the PAD from K to C. So, we should aware that PIN number should be the same as Pad number. When i try to do either of these i can't find my specific PCB PIN to change or PAD to change. How do I get to these menus to change it so the error goes away? ![enter image description here][1] [1]: /editor/20170522/59221f8e771fc.JPG

In schematic, take a 555 as example, select it, then there is `Edit symbol` button, or you can press a hotkey `I` ![enter image description here][1] Then there is a dialog, you can modify the PCB pin at this dialog to map. ![enter image description here][2] [1]: /editor/20170522/592234b8de5dd.png [2]: /editor/20170522/592234e857149.png

So all I would need to do to make these match is change Pin33 in the first pictures modify symbol information to match PIN0 in the second picture (it's in the very center of the IC) enter image description here ![enter image description here][1] ![enter image description here][2] [1]: /editor/20170522/5922376fe8165.JPG [2]: /editor/20170522/592237844a26b.JPG

For your design, you can sikp this error, because there is a pad `0` which is not attached any schematic PIN

It should be attached to ground, per the first picture PIN 33 is PAD 0, why would I need to skip it if it is suppose to be put to ground?

This is from the ATmega datasheet, "Note: The large center pad underneath the QFN package should be soldered to ground on the board to ensure good mechanical stability." This pad is PIN33/PAD0.

Hi, At last you can connect a track to that Pad 0 , such as you can connect PIN 3 to that. so it is GND net.
