Please explain more about your question. I do not understand why you are having a hard time putting traces on the top and one the bottom layers of a PCB: the default in EasyEDA is to have a 2 layer board with the top layer traces in red and the bottom layer traces in blue. There are a couple of examples of how to make fingers along the edges of the board and several ready made pcb packages that are for that purpose. If they are not directly suitable, you can clone and edit them to make exactly what you require. Please also see: [https://easyeda\.com/andyfierman/Welcome\_to\_EasyEDA\-31e1288f882e49e582699b8eb7fe9b1f](https://easyeda.com/andyfierman/Welcome_to_EasyEDA-31e1288f882e49e582699b8eb7fe9b1f) for more help.

The problems I have are many. For instance, when I place a transformer on the circuit board, then creat a pad a inch from it, and go to connect pad to pad, the transformer pad, even though there has to be one there, will not connect as a pad, then the pad I made will not connect to the transformer pad. I creaded a pad on the transformer, even though technically, I should not have to.  Then the pads I put at the edge of the board, I put one on top, then put a pad in the center, then i switched to a bottom view, and put another area of copper, then I could not see the pad on the top. Then I started to think that a pad may not be a hole in the board, so I was going to use a Via, but that can't be right either, so now I am confused.  Can you point me to one long video showing someone creating a circuit board, and saying what he is doing and why along the way?  I will never get this simple board done until I know what I am doing is correct.

I have my PCB laid out how I want it, but I need to add large pads at the edges for connection of wires to the circuit. So the pads I want to be a certain shape, and I need to be able to add wires from the circuit point, to each pad, and each pad need a through hole so the same pad appears on the top, and on the bottom.   Then I need 4 holes, one in each corner for mounting the board to stand-offs.  I am so close, and the only parts that are difficult have nothing to do with the schematic except that the pads are shown on the schematic, so why didn't they transfer to the PCB creation so I could drag them to the board?

Oh, and my capacitors needed to be 5 mm from lead to lead , and I can't find one that is,  So can I modify a generic capacitor to have 5 mm spacing from leg to leg?

@Joseph Massimino, There are too many things to cover to make it practical to present a single video of how to create a schematic and PCB. It is best to start with a small dummy project and learn the tool in stages guided by the Tutorial. Then you can learn all the steps leading up to the creation of a more complex project. This may help explain the issue with connecting pads that are not part of a component and vias: [https://easyeda\.com/forum/topic/How\_does\_the\_Connect\_Pad\_to\_Pad\_tool\_work\_\-JgQO0Ay7H](https://easyeda.com/forum/topic/How_does_the_Connect_Pad_to_Pad_tool_work_-JgQO0Ay7H) However as described in my linked documents above, for successful PCB creation you need to have everything that is on or forms part of that PCB in the schematic. Adding pads directly to a PCB causes problems if you then try to update the pcb from the schematic. Please note that smd pads are placed only on a top or bottom layer and do not have holes in them so they do not connect to any pads placed under them. For something like a gold fingered edge connector you have to connect the pads externally by tracks and vias (or if it is safe to do so as far as the connector is concerned, you can put vias directly into the pads). It is however much better in this case to create the set of connector pads as "All Layers" pads. This automatically creates and places the same pad on the top and the bottom layer and connects them by a plated through hole. "I need to add large pads at the edges for connection of wires to the circuit. So the pads I want to be a certain shape, and I need to be able to add wires from the circuit point, to each pad, and each pad need a through hole so the same pad appears on the top, and on the bottom. These pads are in effect single pin connectors so first create a pcb package as a single "All layers" pad of the shape and dimensions you require, save it with a unique name and a description. Next, add a generic 1 pin connector (from the EELib button) for each pad into the schematic then assign that package name to the symbol you have used in the schematic. That will pull the required pads straight into the PCB. "I need 4 holes, one in each corner for mounting the board to stand-offs." If a pcb package and schematic symbol for the hole you require is not already in the library, clone and edit one that is, save it with a unique name and a description. Assigne the PCB package to the schematic symbol when you save it. Then add the schematic symbol for your hole. That will pull the required pads straight into the PCB.

"...my capacitors needed to be 5 mm from lead to lead , and I can't find one that is..." What type of capacitor is it? What value? Think laterally when you try to search for parts. Do not be too specific. Suppose you want to find a 10uF cap with a 5mm pin pitch. Try searching for 10u and then scroll through for a part with as package that includes the fragment: "F5.0". This is the pin pitch. As an alternative, you can search the LCSC site for a suitable and then use the part number from there to find the part in the EasyEDA SHIFT+F  library. "...can I modify a generic capacitor to have 5 mm spacing from leg to leg?" Yes. Clone it then save it with a unique name and add a Description, including links to a manuafacturer's device page and a datasheet showing the dimensions and if possible a pcb footprint (maybe as an additional link). If no manufacturer information can be found, use a reputable supplier's device page and datasheets. Poorly documented parts may be deprecated.

Andy, let's try this a different way. I created the board on a different web site, but the parts need to be changed.  I saved the board as gerber files, can I upload the gerber files and edit the board in easyEDA?

I think I understand the situation now. You can open PCB files from Altium, Eagle and Kicad in EasyEDA. Please see the Tutorial for more on this. You cannot edit Gerber files in EasyEDA. You can import images of your pcb, assign them to the appropriate layers and then manually replace all the through holes and vias but that is a time consuming and error prone task. Depending on the complexity of the PCB it may be quicker to recreate the schematic in EasyEDA and then create a new PCB from that.

Very good Andy, I got what i needed on the board, except for one thing. The audio transformers have two problems, even though I positively got the correct part from Aliexpress. The lead spacing appears wrong on the grid. The grid is 5mm squares, and the leads are 5 mme apart. They appear as more than 5 mm apart on the PCB.  Second problem is that the audio transformers have a short between two leads on one side, and I can't delete the short. It carries to the PCB and gets in the way of doing what I need to do. At one point, the transformers were 100% correct, and now they are not. I keep going in circles, from one problem I don't understand, to the next.  I was so close to having what I need, except the transformer is wrong now.  How many times am I going to create a circuit board and have something else go wrong. So far EasyEDA has been the best of what I used, and I tried many others, this is too close to give up on it.

For some reason, I can't see your home page so I don't know if what we're discussing is already a public project. If you can share it with me then I may be able to help: [https://docs.easyeda.com/en/Share/Share-to-Public/index.html](https://docs.easyeda.com/en/Share/Share-to-Public/index.html) or: [https://docs.easyeda.com/en/Share/Add-Member/index.html](https://docs.easyeda.com/en/Share/Add-Member/index.html)

Andy, Like I said, I think I have the board done, maybe I need to put some silk screen data on some areas, but the one thing that concerns me, and I have done all I can to make sure it is right, is the transformer lead spacing. I keep checking that I have EI14 red case 600:600 ohm transformer, and as far I I can tell, that it what I have, yet the spacing does not match up with what the grid says it should be. I've gone over this too many times to think this is my fault, I shlould get what I selected.  Can you look at my finished board and tell me that I got it right, or not, and how to fix it if i didn't? Thank you,

Andy, I did verify that the part spacing is correct by printing the PDF, measuring the board, then measuring the parts on the board, and all are correct.

Does your last post mean that you're OK now? Please note that because I can't see your home page, if you make it public you'll have to post the URL to your project.

How can I put pads on the bottom that match what is on top of the board. I would love to fill in some areas with copper left on the board, but I had to do the board over so many times until I learned not to use Autorouter. Autorouter is pot luck, it sometimes messes your board up in a way that you can't fix it, so you start over. I have a board I can have made, but as I said, I want the same pads on the bottom as whats on top, preferably with a via in the center.

That's what the Pad tool in the PCB Tools pallette is for. SelectAll Layers. Choose the pad shape the set the hole diameter. You can use this tool to define a slot too.

Can you tell me what a slot would be like, and what part would go into a slot?

when you set to the slot, you will be able to change the hole length 

Hi John, Why not try opening a new PCB, place a pad and then play with the attributes to get a feel for what effect they have on the final pad shape?

There are many reasons for having a slotted pad... For instance, you might need a slotted pad for something like the tabs on the screening can of a shielded through hole connector. Or to allow for the tolerance on the pin position of some types of wound components (I can't recall the part number but there's one made by Yujing in the library).

I get it, like the tabs that are part of  one end of a fuse holder. They are flat tabs that need a pair of bigger flat holes. So I guess that would require two slots.
