In Eagle, the "Dimension" layer represents the perimeter of your board. You can create a new board perimeter by drawing an enclosed shape using the WIRE command to draw a new enclosed polygon. When you draw your lines, you have the option of changing the wire bend to go straight and then arc (option 6 and 7). I used a width of 0 for the shape.
When you go to export the design, you can export the outline separately or on a existing layer. For example, BatchPCB suggests adding the outline to the silkscreen layer, or having a separate outline gerber.
You will need to send the fab house a gerber file of the board outline. It is in this layer that you will want the rounded corners. You might want to see if you can place a rectangle with rounded corners or change an existing rectangle to have rounded corners. I am not sure of the specifics of this in eagle, maybe someone else can help.
I want to use either ULP or certain menu function to select all vias with certain drill size, how do I do that? I've googled the solution but as what you often get with searching eagle related topics, unhelpful results populated the entirety of the first few pages.
In Altium Designer, all I have to do is to right click one single via of such variety, then select "find similar..." and go from there, but Eagle doesn't seem to have such a humble, down to earth function.
Please do not tell me to disable all other layers but the via layer and select my desired target using the selection tool, I have a large board with nearly 150 vias serving various purposes and discerning them with naked eyes will be an excruciatingly drudgerous task.
Eagle 9.0 and above has a feature that solves this problem, its called the "Design Manager". I had a board with over 600 vias when I realized those used to tie my ground planes together were large enough that they automatically removed stop-mask (exposing the copper). To fix the issue, first hide all layers but the via layer. Then go to the design manager, select the "Signals" tab, scroll to the name of the signal you want and select it. Doing this will select all vias of that signal and you can then apply the change tool as you would for any group of selected components. In my case, I used the change tool to decrease the drill size to a value below the threshold to automatically remove the stop-mask.
I agree with people who commented to your question that to automate the task you may need custom-built ULP. 150 vias is not a big number. I have bigger projects, and I recall I had to find specific vias, and did it successfully by hand. А journey of a thousand miles begins with a single step.
If you are really bothered by the issue, there's official EAGLE forum out there - post request in there, and they will (hopefully) build this functionality into new release, or maybe some expert from community will write needed ULP.
I am soldering a big circuit with many tiny resistors (almost all of them are 0402 in size). The circuit was too dense to put a proper silk screen in place. I'm afraid to make errors, for example soldering a 100k resistor on the spot where a 1k resistor should be.
While soldering, I look at the eagle *.brd file on my computer screen - so I know where to solder what. But I miss something... I would like to highlight all 100k resistors (or other values) at once. That would make my life soooo much easier now
Kudos are much appreciated if the information I have shared is helpful to you and/or others.
Did this resolve your issue? Please accept it "As a Solution" so others may benefit from it.
Great idea to add that post with the detailed instructions! Unfortunately you seem to have made a typo (or a copy-paste error) and duplicated the existing "PCB Service" instead of adding your new button. Oops!
Unfortunately there is a timeout beyond which you can no longer edit your own posts. Maybe @jorge_garcia would be able to ask one of the moderators to correct your post for you if you can supply the info for the change.
That error report is of a syntax error on the very first line of the file. This is usually a result of whatever browser you used corrupting the file. Quite often, it's a case of "oh, this is a Windows 10 box, therefore I'll helpfully change this plain text file to a UCS-2 with binary tag format", which breaks things in far more than just Eagle. The fix, in that case, is to load the file into a UCS-2 aware editor such as Notepad++ and re-save as ASCII (or UTF-8 if there are accented characters in it).
Can anyone tell me how I can connect with autorouter all vias on Eagle using double layer PCB but the connection to the pins of components are only on the bottom side?(because i can't solder all type of component on the top but on the top can running vias)
Sorry for posting here this question but i can't find answer on web..help me please
You could place a restrict rectangle or polygon on the top of the board where you do not want any tracks. So this would be on top of the pins of the connector. This way the autorouter knows it cannot put a trace there on the top and is forced to use the bottom only.
All those green mounting holes will be plated on both sides of the board.
I'll try to remember to take a picture of a similar board at home and post so you can see that.
If you use Edit:View Layers and turn off all but top layer & pads & vias, then do the same for bottom layer & pads & vias, you can see where copper will be left.
You could also use File:CAM processor and create gerber files and review the top & bottom layers to confrm.
If you click Download here
-pcb/pcb-prototyping/im120418001.html
and download the DRC and CAM files, you can run the Design Rule Check to make sure your traces are all manufacturable, and then use the CAM file for gerber creation to see just what will be made. I use the free viewer from www.viewplot.com to look over the gerber files.

Yes I use this function and with it you can made a PCB with Vias and Pad on Bottom and on Top but the problem is that they aren't connect in an Home made PCB and for example if I want to put a 28 pin socket for the ATmega I can solder only the pad on bottom and if a connection start from the top of the pin of the ATmega this connection isn't connect with the pin of the ATmega and that is wrong
Can you answer me for another question please?
I want to cover all PCB bottom and Top with GND and to do this I cover the area with a polygon and rename it with GND name..but a warning occur and advise me that " Signal name 'GND' already exist! use the NAME command to combine signals" and then the PCB's area is cover but NOt connected to GND...How can I solve this?
Odd about the Gnd planes - I do that on every board and do not have that problem.
You will not have much bottom Gnd plane if All your traces have to end up there.
Post your actual eagle files, I can try it when I get home.
Your board seems pretty wide open - why can't you solder those pins on both sides before putting other components around them?
Unless you are using sockets, I could see access being difficult then.
thank you for your Help and for your site to make PCB (please could you link me other sites you know for compare?).
I attach the schematic that it is complete and the board that it isn't complete if you want to take a look...thanks!
I think you are changing the name of the polygon using the info (i symbol in the toolbar) tool? That indeed will generate this error.
To change the name of the polygon use the name (r2 over resistor symbol in the toolbar) tool , click on the polygon and change the name to GND. It may ask if you want to merge the net with the GND net, which we indeed want.
Thanks for your time but with a home made pcb I think that is difficult to sold on top some components like for example the crystal...I used 25 mil for via because i'm afraid to lost vias during the process to do the physical sircuit board but I can try with this configuration....different is if I use site like that you link to me but I learn to create the file to send they....Do you know a guide to learn this?
Another question sorry
How can I do the operation you can see on the photos? I try to delete the GND for connect a blu wire but I don't know how I can do....can anyone help me another time please?
I think this might do it for you.
Need a few jumpers to complete all the signal paths, shown here as the red wires.
All the components are soldered from the bottom.
I'll leave it to you to make any traces wider if you want them to be.
I made the vias for the jumpers the same diameter holes.
Generally speaking, Eagle polygons are not zones in the way Kicad polygons are, so pullbacks/clearances around their perimeters in kicad may also differ to those in native Eagle representations, and via clearances may not convert simply.
I at least abbreviate that you sometimes point to it. At lest when it has a feature that is kind of missing in kicad. (It is open source which means anybody can take that part of the code and create an eagle importer with it for any other system. Assuming the licenses of both projects are compatible.)
