drill data generation & update

When processing drill data in preperation to generate gerber outputs, I

have

not yet found a way to automatically update the drill table in Options

->

Set -> Drill.   Clicking the "SET" button on the Drill table does

automatically extract drill sizes from the current project, but does

not

sort them in increasing diameter (I would prefer it did).  But even if

it

did sort them, it is still a manual process.  I can't even find a way

to

execute that "SET" button command through a .ULP script.

I'm not following what you're trying to accomplish.  To "process drill data

in preperation to generate Gerber outputs", you usually run the DRILLCFG

ULP.  This makes the .drl file, which contains the list of drill sizes

used.  The excellon CAM processor job then uses this drill list to create

the .drd drill data output file.

I don't see what any of this has to to with the SET comand or why it

matters what is in the pulldown list of drill sizes (which is the only

thing that list sets as I understand it).  By the time you run the CAM

processor, all the drill sizes have been determined by whatever means and

you shouldn't be trying to change them at that point.  You can't just go

changing hole sizes after the fact without problems.  If you make the holes

larger than intended in the library package, it could cut into something

else or make the ring too thin.  If you make it smaller, it might be too

tight for a part's leads.
