Furtheroutputdevices
If you prefer drill data in another data format like Sieb&Meyer 1000 or
3000 (SM1000, SM3000) or to work with the Excellon format that
EAGLE used in its previous versions with a separate rack file (now
device EXCELLON_RACK) a drill table is required first. This is cre

DrillDataforMultilayerBoardsWithBlindandBuriedVias
The CAM Processor generates one drill data file for each via length for a
layoutthatusesblindandburiedvias.
The file extension .drd is expanded by the via length specification. If
there are, for example, vias from layer 1 to 2, the output file extension
willbe .drd.0102.
The layer specification can be moved to another position with the help
of the wildcard %L. Writing, for example, in the File box of the CAM
Processor .%L.drd results in an output file with the file extension
.0102.drd.
