Find drill by size on PCB [message #170929] Tue, 11 July 2017 17:46 Go to next message

Hello,

Does anyone know a quick way to find a drill on the board by size?
I have a fairly good size board and have two drills almost exactly the
same size and would like to merge them.
I did not have control of the library parts so have no idea what part(s)
the odd size drill is in.
Staring at the sea of drill symbols on a large board is not an
attractive option.
Ideas anyone?

Thanks,
Doug

Why not open the .brd file in an XML or text editor?

You should see lines like these:

<hole x="7" y="31.25" drill="2.5"/>
<pad name="1" x="0" y="0" drill="1.016" diameter="1.8796" rot="R90"/>


Regards,

Dietmar

You could use the following ULP, downloadable from
http://eagle.autodesk.com/eagle/download/2087

drillinfo.ulp

Then you will know which part has the drill size of interest.

You will still need to get at the library to change it but this is possible by exporting the libraries from the schematic or board. There are few precautions needed to achieve this.

You may not need to do anything. The manufactures often only drill to their drill sizes and if your two sizes fit within the one range they will be drilled with the same drill - job done.

Thanks Warren.

My problem came in when there were too many drills and Eagle ran out of
symbols.
When I looked at the sizes they were about 0.16 mil apart.
Fixing was easy, finding was the challenge.
Thanks for the suggestions. It is happy now.
