I created a footprint only composed of pads. The pads were converted from circular-shaped tracks. The 3D preview looks like what I am expecting, but the 2D preview shows that the inner part of the pads will expose the copper (after creation of the copper area). I was not able to reproduce the problem with only one circular pad, so I don't know what I've done wrong here. :/ Here is a public project showing the problem: [https://easyeda.com/bencfd/exposed-copper](https://easyeda.com/bencfd/exposed-copper)<br> <br> Any help will be greatly appreciated. Thank you in advance.
