Move pin name text in symbol editor

Is it possible to move a pin's name in the symbol editor. For instance, if you were drawing an LM317 symbol and wanted the In, Out, and Adj to appear outside of the body of the symbol rather than inside of it, could you do this without simply creating separate text files? Is there a way to reposition these? If not, then I know I can just use the text tool. Just curious about that.

 

I'm also curious if it's possible to give the pins a different name/number. For example if you were using an LM317 in an SO8 package, the In would be Pin 1, the Out would be Pin 2, and the Adj would be Pin 4. I know you can assign this in the Device rather than the symbol but I do like it when my Symbols match my Packages pin numbering-wise.

 

Thanks in advance

Hi @cdenneyB9ZMH,

 

Thanks for your participation. The pin text is not moveable, so as you have already mentioned what you have to do make the pin text invisible using the properties and then using the TEXT command add in your own text.

 

In the symbol the pins will only show the pin name, once you go into the device EAGLE will reflect the pad numbers on the symbol automatically, again the pad text are not user modifiable. Depending on the package variant in the device the Pad numbers will update automatically so for different packages you'll get different pad numbers on the symbol.

 

Please accept as solution if my post fully resolves or you issue, or reply with additional details if the problem persists.

 

Let me know if there's anything else I can do for you.

 

Best Regards,

I suppose I'm making a futile effort to use Eagle the way I used CircuitMaker/Altium of which I'm far more familiar with. To me, the way that Altium handles this situation seems to be the more appropriate way but I could definitely see somebody disagreeing with me on this point and suggesting the way EAGLE handles it is the more appropriate way.

 

Either way, it will get done and I'll have a working circuit. Thank you for your help.

SUGGESTION:

Make the pins smash-able from the symbol editor only. Being able to change the size and location would go a long way to prettier schematics.

C.Nicks - It's funny because this is exactly what I had been trying to do. I kept typing "smash" in the command line but it would just tell me it can only be used in a schematic or board editor.

 

I completely agree with C.Nicks on this one. Making the symbol 'smashable' would go a long way in making things neat and tidy. One of the risks with the current method is that you need to be very careful when you are labeling the pins, otherwise you could completely screw up your schematic.

 

For example, in the example above with the LM317, what if when I went to add text to the symbol, I accidentally put the "In" text on the Out pin and put the "Out" text on the In pin. Then when I did my layout I wired it up according to what I labeled everything, I'd have a bad circuit and would be struggling to troubleshoot it. If we could Smash the symbol instead, then the risk of labeling the pins wrong would be virtually eliminated.

Totally agree.  You get an Upvote from the dev team.  :)  We'll get this on the list of stuff for us to implement.  We are doing a lot of work on libraries at the moment but of course this takes some serious care to not screw up people's existing content.  We'll look to get this capability scheduled and try and implement this in a future release.  No promises yet on when we do it, but it's something we need to do anyway to support importing libraries from other systems, so we'll have a look at it.  

 

Thanks for the suggestion!

 

Best regards,

 

Matt.

I found and modified a useful ULP last night that essentially mimicks smashing the symbol pins. It only works on the pin name and not the pad, but it may be useful to someone.

You can easily change the text size/ratio, location, and pin visibility by editing the file.

 

Current defaults:

Layer: 97 info

Size: 0.06
Ratio: 8

Offset: 0.15 (good for middle length)
Visibility: Pad numbers along with generated smashed texts.

 
To change visibility of pin, change pad on line 72 to "off, both, pin, or pad"

That's really neat C.Nicks. I'll have to give that a shot.
