Eagle question
« on: February 23, 2018, 05:40:55 am »
Please understand me, I'm starting at this and I'm probably making so much mistakes that you are cringing on the other side of the screen.  :scared:
Anyway.
I'm currently learning to use EagleCAD and I've been designing what ever and wherever.
I'm currently making a boards that takes the pinout of a 9 pin miniature vacuum tube and distributes it to 9 terminals.
I wanted to put a Ground pin on the grounding plane, but I can't seem to figure out how to do so?
Can someone guide me and fix my mistakes hopefully.
Thanks

I'll upload a picture of the full board later.

You already named the ground net in the schematics as GND right? (should be, as they're connected to GND supply symbol)

Then, You need to rename your ground pour/rectangle/polygon in the board editor with the same name (GND)

Use the Name tool.

Click one of the edge of your pour/rectangle/polygon, and rename it.

The pour might not automatically updated, use the Rastnest button to force update.

If I'm adding a bunch (usually) of GND vias, I find it more convenient to:
  • use the text command window to enter via 'gnd' command, which names the vias as they're inserted...
  • or (once you have the first properly named via), use the copy command to make new copies to plunk down. (don't group a copy a set of GND vias, or it will rename them to "GND1")

From the looks of it. It looks like the pad is properly connected (in schematics) but the pour itself is still default named.

Yeah, that'll cover the other possibility too,  I guess...

Thank you so much. I realize now that I probably should have posted this in "Beginner" section.
That seemed to be my problem.
I'm wondering if a "measure" tool exist?
It probably doesn't, but it sure would be nice to measure the size of something.

I think I'm done with everything. Any suggestions?
I know it's quit simple, but I'm just trying things out.

Tube are high voltage, right?  Do something to increase the clearance between the ground plane and the traces, either in the drc , or via "class", or "change isolate" on the polygon.


There are a couple ways to measure.  Use "mark" and the status bar will show the distance from the mark as well as absolute coordinates.  And there's a measurement tool.  Or what I usually do is draw a line on some innocuous layer, and the use "info" to see how long it is.

Thanks will do.
The tubes I use don't go past the 200VDC range.

You might also want to use standard spacing for your pin headers.   Using the 3-pin or 4-pin (for ground) versions will ensure that, regardless of whether you use 0.100" or 0.156" spacing.  Many single-pin female connectors are not very durable.
