You have to assign a netname to the copper area. For example, if you have a ground net on your board called GND and you want a ground flood connected to it then you have to enter GND in the "net" attribute of the copper area. You must also always very carefully check the Gerber files for your PCB before submitting for manufacture. If you had done this then you would have picked up this mistake. This is why I recommended reading: [https://easyeda\.com/andyfierman/Welcome\_to\_EasyEDA\-31e1288f882e49e582699b8eb7fe9b1f](https://easyeda.com/andyfierman/Welcome_to_EasyEDA-31e1288f882e49e582699b8eb7fe9b1f) where points like this are covered in detail.

Thanks, I got that, but maybe you could tell me what part number you gave me for a square pad with a hole? I can't get it out of my old schematic, it comes up blank.

@Joseph Massimino Joe, If you go to libraries in pcb editor, and search 'Square Pad', you will find many already there, some with holes. If you even find one close to what you want, simply modify the the numbers on the Attributes Panel on the right to change the size square, and hole diameter. I am not being condescending here, but if it is just a square pad, this should be very easy to just re-create to your own specs. This sounds like about the simplest part you could make. Then name it, and save to your personal parts file. It should be faster to re-create it then go searching for it elsewhere or even edit an existing one. -Lisa D

@Joseph Massimino I took a look at the board you have showed in the forums. Is the pad you are looking for one of the square pads on the left and right sides on the board? If so, the Pad has a package name of HDR1X1. Search Libraries/ click PCB_Libs in the top row, and then search the various options like, Personal, User contributed, etc. I found it in there, then you can just click on it and hit 'place'. -Lisa

I can't find the thread in which I mentioned a specific part number. I did describe how to use the Pad tool in the PCB Tools floating pallette, as Lisa described above. As described in the linked documents in: [https://easyeda\.com/andyfierman/Welcome\_to\_EasyEDA\-31e1288f882e49e582699b8eb7fe9b1f](https://easyeda.com/andyfierman/Welcome_to_EasyEDA-31e1288f882e49e582699b8eb7fe9b1f) if you want a dedicated pad on the PCB that doesn't get deleted every time you update the PCB from the schematic then create a PCB footprint for it, save it with a unique name and include a Description. Then place a suitable schematic symbol in the schematic and set the "package" attribute to the name you have given the PCB package you have just created. Then when you first create - and later update - the PCB from the schematic, the correct package will automatically be pulled into the PCB.

@LISA_DALTON Yes, that looks like the pad I used, but it is in PCB, and I can't insert it into my schematic to have it be controlled by the PCB generator.  I had some sort of pad that could be placed in the schematic and be handled by the auto router properly. The routing I do now, once I run autorouter, it screws up all the traces, and I have to delete them, put them back, and try again. Each time, autorouter puts the traces where they don't belong.

@LISA_DALTON  I guess the real problem, is in mixing through hole and surface mount parts, then trying to use autorouter. It does not route properly when surface mount parts are uses with through hole. No matter how many times I try to fix it, the Autorouter messes it up.  I might have to get use to using via's, and wire the board entirely by myself. The problem I faced with via's, is that once ia run the wire on top, place the via where I stop, when I switch to the bottom and try to attach the wire at the via, it won't attach. The software should give a clear indication that it attached to the via, so the user will know that what they wanted to happen, happened. I do get it to place, but not in a way that I feel like my goal was reached. So to be clear about what I am saying, if a user is placing a wire on a Via, just the way it warns about bad connections, it should ask if you are connecting to the Via. All you do is say yes, and it will happen, and you have positive assurance that you connected to a via, and nothing else.

I will have to delete all wire on the schematic, as it does not let me correct what it did in creating the circuit board. There are connections that don't exist in the schematic, that the autorouter made from creating the PCB, and once that happened, they can't be corrected, or deleted. The new update might be the reason, or the mixture of surface mount and through hole might be, but it is one bug in the software that it making this board very difficult to get done. It should have been simple.

@Joseph Massimino Hi Joe, It REALLY sounds like you are not using the layers correctly. I have never had 1 problem with using SMD and TH parts. There are no bugs with that I have found. There is actually a 'Yes or No' system for if the trace connected or not, if the Ratline goes away it connected, that simple. I believe you are not changing layers when you should. But without seeing it happen, it is a guess. Here is something that should get rid of allot of the confusion. Use the design manager on the left bar, click first on nets, and look for red x's indicating you made an error. Do the same for DRC. You MUST get all the errors taken care of first, (most of which you wouldn't have noticed if not for using the DRC, (Design Rules Check) ) Once all errors are gone, then and ONLY then can you start to route the board, either by hand or using Auto Router! Else confusion will ensue! Do the DRC check and I bet you find many things to fix. (Also Nets). -Lisa

@LISA_DALTON Sorry,  I missed the part about the the square connection being for the schematic. As Andy said, you will need to make a schematic symbol, seeing as it is just a pad on the PCB, You can make any simple shape, like a circle, name it's schematically, then on the right panel, where it says 'Package' Assign it the pad name for the PCB: HDR1X1.  Now you can repeatedly use that part (connection) not only on this board, but any in the future. Let me know how it goes -Lisa

Lisa, I had finished the new board, and I added a pad to the PCB from the PCB menu. I connected my circuits to the pads I created, but when I was completely done, every single pad resulted in a DRC error. So when I did the Gerber view, I told it to ignore the DRC errors on the pads, and the gerber view looked perfect. So that only makes me question what those DRC errors really means in terms of having the board made with the DRC errors going unchecked?  The copper all looked correct, so that is why I have to wonder about DRC. What do you know about that? Joe

Please tell me how I can share my board with you so you might see what I did wrong. The DRC Errors are all in the pads I created, and attached my circuit to.  The Gerber view looks perfect, but as you said, it won't like the DRC errors, so they have to go away. The only thing I did was delete one trace to a pad, then try to use pad to pad wiring, but that would not work. My best guess is that because I added the pads on the PCB, they are not being recognized by the schematic. So maybe I can't connect anything to them because they were not added at the schematic level. Right now, I have a DRC error for every pad that I created, and I can't do anything to make the error go away. so now I have to wonder how I am going to fix it. Joe

Lisa, I checked each pad, and i see they all have the same net number. Is that the problem, can I fix it by deleting all the net numbers on the pads?

John, Your pads and vias must have the same net names as the nets to which they are attached. It sounds like you are adding vias in the PCB the wrong way. At the moment you seem to be going round in circles. Please study the Tutorial carefully to understand how to do this. May I suggest that you stop working on your project for a bit and create a new one just to practice creating a simple but fully documented schematic so that you can pass it into PCB and then work on it so you can get used to  all the features and following the recommended Design Flow of the EasyEDA. Then go back to your real project and see how you get on.

@andyfierman  My name is Joe, I did stay up late last night and finally figured out what was causing my problem. When I search for the pad i wanted to use in schematic view, it did not come up, so I made the pad in PCB view, and that was wrong.  Last night I search again, and found the HDR1X1 pad I needed in schematic view, so I deleted all traces and pads from the board, added the HDR1X1 pad in the right quantity to the schematic view, the updated the PCB view where all the pads were waiting for me to use.  I reconstructed tha board using those pads, and connected all circuits in PCB view using pad to pad. After I put a few traces on the board, I auto routed it, and continued until the whole board was done.  The board passed the DRC check with zero DRC, and it generated beautiful Gerber images. I also learn a few other things by watch some of the demonstration videos on using via's, and grouping, I now have a better understanding of the who process. Now I understand why you suggested that I start over, it is difficult to know where a problem originates, so the best course it to study the system, and back out of the project and start over with the new found knowledge. The traces that were coming up that I had no control of, were traces that were part of grouping, and that was done by mistake. I was very careful when i put the parts back on the board, it is very easy to click more than one part, then group them by mistake.  The inverse of that is to remove grouping from a single part, that can be a big problem if you don't notice that it happened. What I mean by that, it if you have a surface mounted diode, and you un-group the pad from one side from the other.  That can happen, and it did, and I had to try to fix it, but in the end I just deleted the part and generated a new part to take its place. One thing that someone new to the system should know, is that surface mount parts come in various sizes, so if they are 1206, you have to make sure you are placing a 1206 part on the board, or your parts may not fit. There is a giant learning curve to using EasyEDA, especially if you make multilayer boards. I am happy to be on the down swing of what I need to know to get a good board.

Joe, My apologies: I don't know why I got latched onto calling you John! But well done for persevering. For your next project (and I still recommend that you do a simple but complete project all the way through to generating and checking a properly formatted BoM and the Gerbers), take the time to create the complete schematic first and then check it to death before you even think about clicking the "Create PCB" button. Once you have a complete schematic with no errors then when you generate the PCB from it, it should literally just be a matter of moving the parts - including things like mounting holes, logos and/or warning labels - into place and then replacing the ratlines by drawing in the traces. Don't get too in love with Autorouting. Unless you really understand how to route a PCB to allow for ground and power planes, trace widths for power routes, routing for decoupling and all the other issues of Power and Signal Integrity and layout for EMC, then simply letting an Autorouter go tearing about routing your PCB can give you a board that might be connected correctly but which for various reasons does not work properly. If you route the PCB by hand you will find it's easier than you think and by following some basic rules, you end up with a board that has less room for avoidable layout errors and which is easier to debug because you know exactly where all the traces are and how they're laid out. It's important to remember in EasyEDA (and in most other EDA tools) that the Schematic is the master document so if you need to change something in the PCB, like adding extra decoupling or changing a component type or package, then you must do it in the schematic and then pass the changes into the PCB from the Schematic Editor using the "Update PCB..." button or in the

(Accidentally pressed Post...) ...using the "Update PCB..." button or in the PCB Editor using the "Import Changes... button.

Andy I agree with all that you said. The board I created has three separate circuits on it and only two of them get power. The one circuit that gets power is simple in that it is the optocoupler, and its power connects very close to the part.  It is not a constant voltage, it is a voltage that is only present for a second or two at a time.  I would have a whole new learning experience if I ever laid out a board with RF components, and or other powered circuits. I'm contemplating my next project now, and it will involve a microcontroller,  and some other parts that are associated with it. I have some two pin terminals that i would like to use on the next project. They are very common, so it would be just a matter of finding the right hole pattern for them.  The good part about that is when i print a PDF of the board, i can test the parts in it to see that they fit the way I want them. Thanks for all your help. Joe
