PCB designing: facing problem in connecting pushbutton

eaglepcb-design

I decided to learned PCB designing using EAGLE 7.1.0. So I first of all I go through this video then through this video.

Now I started designing a board for ATmega16 microcontroller. For this I simply connect a resistor on RESET pin, And check it on board layout, till now every thing fine. Now I decide to design a library for push button, for this I follow this video then this video.

Now I connect this push button with RESET pin to complete me reset circuit. Now, when I check out Board layout, there no connection between ATmega16 and push button. Here is schematic and board layout

Board layout:

You can see Push-button is not connecting to the chip. Why?

Best Answer

First of all, your PCB footprint is incorrect. Outline of the button is to be drawn in tPlace(which is light gray and means physical shape of package) and not in Top(which is red and means copper).

The ratsnest is not showing up probably because you have connectivity problems. Check the part in library editor, whether it has PCB pads assigned to symbol pins.
