Thomas,
You have a good point. Creating the Fab drawing with a hole chart for a
design with just top to bottom drills is very easy. It's starting to look
like creating this for a design with different types of drills (blind,
buried & thru) is really a pain.
From the look of Darwin's PDF, he spends a bit of time on it. Not sure what
I'll do. I've always created a Fab drawing with the hole chart, and now
Allegro automatically creates multiple drill charts. I guess I could just
line them up and have all of the different drill figures within the one
board outline.
Thanks for the questions!

-> Hi All
->
->
-> For whom are we spending time on making drill charts and drill films ??
->
-> Quality control : Can't count silver plugged vias , buried vias,
-> microvias.
->
-> PCB shop : They get drill files and they have super duper fancy CAM tools
-> so if they want drillcharts they can print them
-> out.
->
-> Do we really add any value by spending time on making a
-> graphical image of
-> whats already in the drillfile ??
->
->
-> Are they really needed or are we just wasting time ??
