Change restring for one specific component

autodeskguest

I had a problem with some of pads not printing properly and wanted to

change the pad size.  Someone pointed to DRC, restring and I was able to

increase the size of the pad which worked wonderfully; actually too well

since the pads of a TO228 are now seemingly too close together.  Is

there a way of either excluding pads from changing sizes or to select

only those pads that you want to changes sizes?  Thanks

    You will have to change the part in the lib and then do an update. There

    may be a auto size property for each pad that has to be turned off so

    you can change the pad diameter.

     

    Once you get the learning curve down on lib editing and updating is

    would only take a minute or 2 to make that type of change to a part.

    Exactly.  Changing library package details afterwards is dangerous.  The

    right way to do this is to update the library.

     

    If the pads are too small for the hole that the part needs, then that is a

    error in the package and should be fixed.  If you just want larger rings

    around pads in a particular instance, then you should create a new package

    with the larger pads and add that to the same device.

     

    In general, wanting to change such things at the board level usually means

    you're not thinking something thru correctly.
