cutting down number of drills

If some of the the drills are of almost the same diameter (like rounding

errors from inch to mm), maybe you could get away with using the

EXCELLON_RACK device to produce a WHEEL file and playing with the

tolerance parameter. Eagle will group drills within this given tolerance

together. When using the EXCELLON device this option seems not to be

available, but you could probably edit the resulting file by hand, to

manually assign a diameter to a drill.

 

This would, of course, not change the design, only the output. If you are

looking for a way to cut down on tooling costs, maybe this is enough.

I edited the some of the more obvious vias with the change tool. Many of the

other holes are part of library elements and didn't want to start playing

with that yet. May be a non-issue. I sent off a preliminary fileset to board

house for review and will see what they come back with.

Would have been nice if the change command had an option for Change Drill

The drills in pads are specified in the libraries so one should

establish/limit your drill selection there.

 

Your situation maybe a bit tricky. More information is needed.

If the board came from elsewhere and not using your libraries you could

export the elements, (exp-project-lbr.ulp) , modify the drills and then

update the board.

 

There are a few other drill focused ULPs around to help. Checkout the

CadSoft download area.

drillcount.ulp will give you something similar to statistics-brd.ulp

round_drills_mm_all_.zip  Round drills/holes to 0.1mm multiple in a

library.

drillinfo.ulp lists which part from which library causes the 

non-standard

drill to be listed by drillcfg.ulp

fixdrills.ulp This ULP rounds drill sizes to the nearest mil. Originally

created by Chuck Huber

Thanks Warren.

I had been using an older version of drill-legend.ulp which was a bit 

limited. Found a newer version named drillegend.ulp that was included 

with Eagle 5.11 that is showing and has symbols for all my current 23 

drill sizes. Many of these are close in size and can be consolidated.

 

Will look at your suggestions but for now at least, I have a decent 

print where I can identify by symbol, all the errant sizes.

 

This board was likely started with inch drills and later on converted to 

metric sizes, accounting for the odd numbers.

Sad to say, the original designer (also company founder/president) 

passed away recently, leaving me to move all the designs forward.

Have you tried Options->Set->Drill->Set ?
