[PCB_FORUM] Re: drill symbols

Gary,

Set the figure as a circle that is the same size as the drill.

Drill Dia = .062
Figure = .062
Character = P ( P= Plated, N = Non-Plated)
width = .062
height = .062

This way the hole and the drill are always the same, Now you
have one to one correspondence and one would never run out
of figure combinations.

Side note: This is how in the old days I would get the drill size to display,
before the display button was added.

In this electronic age, each of the vendors, techs, engineers I work with has a copy
of the Allegro viewer or a CAM tool. If anyone wants to "really" know the
diameter, then they hit the "information" button.

Hope this helps.
Dave

Hey all,



The padstacks in our library have a unique drill symbol for each drill size (either a "Figure", a "Character" or

a combination of the two).

This is a "mature" library, and I'm starting to run out of symbols with all of the odd drill sizes I'm adding lately.



What do you do when all of the combinations are used up? Anybody else have this problem?



Thanks for a clue!
