Hi Kindlyhenry, This suggests that, for some reason, EasyEDA is not seeing your "soldering pad" as an actual pad. Can you post a link - or just the name of - your footprint to see what the issue might be?

Hi Andyfierman, Please go to my parts-->package-->untagged, footprint name is L 12x12 Solder pad

Hi, You don't need to add solder mask, EasyEDA will help you to add them automatic, you need some special, you can check https://easyeda.com/Doc/Tutorial/FAQ.htm#How-to-add-solder-mask

Hi Andyfierman, Attached a picture to show the problem. ![enter image description here][1] [1]: /editor/20170518/591d8f00cad58.png

Hi Kindlyhenry, While I check your footprints, have a look at how I made these: `6MMPAD` `8MMPAD` `10MMPAD` You may be able to clone and adapt one of those and re-use it in your footprint. See also this thread: https://easyeda.com/forum/topic/Link_SMD_pad_to_bottom_layer-c0UcuLrXf as it is relevant to your problem. :)

hi Dillon and Andyfierman, Thank you so much for your effort, problem solved!
