I have found a handful of these occurrences on my most recent board, and it makes me feel uneasy that I may miss one.I use SparkFun's DRC, but I don't think that is the issue because it visually shows the error.

content: Hey guys, I'm somewhat of an Eagle n00b. I used it a bit a few years ago, and am now re-learning a lot of stuff trying to make this project go. Anyway, I'm trying to add a new package to an existing part and am having issues getting it to work.So I open the library, browse to the part in question, add the package, connect the pins and everything looks fine. I tell Eagle to update all the libraries, and... the new footprint for the part is not there. If I click 'add' in the schematic or board layout window and browse to the part in the library, it's not there. If I go to the Eagle control panel and browse to the library, the new variant is not there. If I open the library to edit the part, the new variant is there. So it's there, but it's not. I can edit it, but I can't use it.Anyone have any idea what's going on?

content: I've always enjoyed finding ways to use Excel to make my job easier. I've put together the below spreadsheet to easily create larger footprints.There's still some work to make it more automated, but the idea is that you would update your pad information, create additional rows depending on the number of sides and pins you have, and then drag down the formulas.When you've done this, you simply need to copy column F and paste it into the command area in Eagle and you can watch your footprint being created before your eyes. It's actually kind of fin to watch on larger packages.Enjoy!

Rat's nest doesn't see ground pour? - Eagle 7.0 - Page 1

content: Well, here's one I've never encountered before. Working on the board for a little TSSOP breakout of mine, got a nice ground pour going, should be great, right?Guess not. 2 Vss pins and some of the SMD caps are pretending that the ground pour isn't even a thing. It connects to the pads just fine, but then it's like the rat's nest can't find the entire ground plane.I haven't punched any vias to connect the top and bottom pours, but it shouldn't matter, since it's a solid piece of copper up top (let's forget about noisy grounds and such for now). The pads are physically touching the copper, but it acts like no connection is being made.Anyone else hit this issue?Ground airwires highlighted in (garish) green.

timestamp: November 15, 2014, 06:35:21 am
content: Such circles are commonly part of a drill hole. A drill hole will contain data in dimension (20), tStop/bStop (29/30) and holes (45). In the case of a hole, the actual component you can edit, delete etc is in layer 45. To complicate things, the hole may additionally reside inside a component, which makes it impossible to edit it directly, instead you need to delete the component that the hole is part of. Usually, displaying all layers will clear up the situation.(I'm posting this even though the problem was resolved.)

EAGLE - converting polygon to a line? - Page 1

timestamp: October 30, 2014, 10:17:47 am
content: So, I designed a nice PCB outline in Inkscape, namely a hyper-ellipse using built-in function plotter. There is a script, svg2poly.ulp that allows to import a SVG path as a polygon to Eagle. I import it to the Dimension layer. Is there a way to convert a polygon to a line? Does the Dimension layer require lines, not polygons?Another unrelated question: I will send Gerber files to the board factory. Are there practical limitations on the number of vertices in polygons or lines? My design uses ~100 vertices.

content: QuoteThat's a good question. It may be pcb-shop dependent. Probably, though; polygons apparently are fillled, by definition, and result in a gerber containing essentially a bunch of raster lines.QuoteProbably. But it's probably easier to modify the svg2poly script to produce lines in the first place. It shouldn't be too much more difficult than replacing a piece of text command that says "poly" with "wire"...

content: I've searched, but I can't find the answer to my question. When I first open a PCB, Eagle doesn't show the ground pours, so it's easy to see the traces on the top and bottom. When I click the ratsnest tool, it adds the ground pours. So far so good.Is there a way for me to go back to not showing the ground pours without having to close and reopen the PCB? There are times when it's much easier to route a wire when the ground pours aren't visible.

timestamp: August 12, 2014, 03:11:21 am
content: You can undo the automatic filling of the polygon by using the ripup tool on the polygon(s). It will be filled again the next time you do a ratsnest.Another option is to temporarily change the pour type to cutout, but I believe you have to change this back to solid or hatch before exporting the board to actually get your ground plane into the gerbers! So only do this while routing, and change it back so you don't forget it.

The wrinkle is that the two pads are electrically connected by the part. What I want to do is drop a polygon on both sides of the board between the two pads to make a two-hole "über" pad.I can't make the two pads the same name. I can't name the polygons at all. I can connect and append the two pads to the same pin on the symbol, but I wind up with an airwire between the two pads I have to ignore.1. Is there a library for this part already somewhere?2.

According to that tutorial the more general ones are gerb274x.com and excellon.com but he did his own that combines probably both.

content: If you use Gerber 274X, Excellon drill format etc. it should be broadly compatible with every fab house.Keep the file extensions the standard ones, that describe the layers:Bottom Copper: GBLBottom Silkscreen: GBOBottom Soldermask: GBSTop Copper: GTLTop Silkscreen: GTOTop Soldermask: GTSDrill File: TXTDrill Station Info File: driPhotoplotter Info File: gpiMill Layer: GMLTop Paste: GTPSometimes some fab houses insist on something a little extra, eg. OSHPark wants a GKO (Gerber Keepout) file containing only the board outline, so OK, might as well add that to the CAM processor and keep it in there for any fab house.Personally, I wrote a makefile that does CAM generation:https://github.com/lukeweston/eagle-makefile/blob/master/makefileYou can edit it to taste, for example to add the GKO layer, or change the layers you want added to the silkscreen, but this gives you the basic idea.Sometimes PCB fab houses will tell you they can't fab from your files because you need to do your layout differently, or you should change this or change that, or give your files a different name, or whatever, and personally if this happens and your files are manufacturable and you know what you're doing and your boards pass DRC then you might want to just find a different fab, because I personally just want a fab that "just fabs it" without telling you how to do your job, although in some cases like for beginners this sort of advice may have a valuable role.

But I can't figure out how to pan with the mouse.BTW - if I uncheck legacy mouse wheel mouse, I can pan all around by sliding my finger on the mouse, but I can't zoom. I prefer the zoom scenario, but it would be nice if I could hold shift or something to pan.

I design them with the EAGLE software.I can make simple pcb's, but complex pcb's with more (fine) traces and smd parts are harder to make, and sometimes i fail to make them, but i think there's a solution for my problem.After i finished routing a project in eagle, can eagle make the traces bigger where there's enough space for it? Is there any ulp that can do this?Milling 0.6mm traces is quite hard with my machine, but it will be a lot easier if eagle can make parts of the traces 1-1.5mm. I would get better results when this is possible.
Editing footprint solder mask in Eagle - Page 1

I really like its advanced high-speed features (differential pair routing, length matching, miter etc) which are great for complex designs.I'm trying to create a footprint with custom solder mask and paste mask. Basically it's a 1mm diameter fiducial mark that has a 3mm dia. solder mask and likewise a 3mm dia. paste mask.Do I somehow edit the default ones or is it done another way?

content: When you draw a surface mount pad in a custom Eagle library package, it has a solder paste stencil aperture (aka "cream" layer) and a solder mask aperture (aka "stop" layer) automatically generated with it.I think these can dynamically change when the component is in your board layout, based on DRC settings.To turn off the "automatic" generation of these layers, change the "Cream" and/or "Stop" properties of that copper pad in the package, and turn them from "on" to "off". Now you've got just a copper pad, no soldermask or paste layer. Now you can use the draw-rectangle tool, on either the stop layer or cream layer, to manually draw a fixed rectangle around the pad for that layer, with exactly the customised dimensions that you control.

Right now I'm deleting them and redrawing them. Eagle's GOT to offer a better way, yeah?Edit: the move tool can straighten them out sometimes but it's very fiddly and often ends up dragging the wrong side of the wire. Seems equally as irritating as delete-and-redraw.

timestamp: February 15, 2014, 10:45:51 pm
content: Instead of moving a single component, you should group the components that should remain static, and then move them as a group.In your example, I'm assuming you moved the R-Pi down. Instead, you could group the R-Pi and also the three wire vertices (corners) to its upper left (a total of 4 objects). Then move them as a group down. The wires coming out of the R-Pi would then stay at a right angle and the 3 vertical wires would adjust in height.Alternatively, after you move the R-Pi as in your picture, you could group the 3 wire vertices and move them into position as a group. There's no need to move them individually.

My Eagle version is 5.5. I make my own PCBs using PulsarFX and the part worked ok for me.While I'm fairly certain that the symbol & foot-print are accurate, you should double check it prior to committing the artwork, just to be safe. Always print 1:1 test-plot to check alignment of things.Good luckbench_knobps...I uploaded a tutorial for making parts, its really easy to do once you know how.

content: Quote from: Kirigozo on October 31, 2013, 01:48:58 pmI don't know if there's a way to explicitly disable it completely. The follow-me router is included as two of the ten (or so) "wire bend" choices. If you choose a manual wire bend (like 45 or 90 deg) while routing an air wire, the follow-me router will not be invoked. You can right-click to cycle through the bend choices while routing or click on the bend icons at the top.I have my wire bend choices limited to *not* include the follow-me router with the following command in my eagle.scr startup file:set wire_bend @ 0 1 3 4;This limits the right-click choices to cycle through only the 45deg and 90deg bends. You can still override the choices by manually clicking on one of the bend styles at the top, including the follow-me router. Read the help for the "set" command to decode which choices the numbers map to.I find the follow-me router to be slow, jumpy, frustrating, and generally unusable.
