Interpreting Gerber Drill file

[apstndp]

Hi ,

I have created the gerber drill file and the same attached here. (In Allgro)
I have some confusion how to interpret the data from drill file.

The Tool "T01" is used for total 118 drills. But total number of line items in drill file shown are 111. What happened to remaining 7 drills ?

Is that data is encrypted in the drill file ? There are some different codes other than the locations specifying x and y location of the drill , like R04X00100 etc.

Can any one explains about this ?

Thank you,


Regards,
Siva.

It is probably to do with the R codes - repeat patterns.
