Page 2 has the Drill table and Drill Chart for Layer 1 to 16.




Page 3 has the Drill table and Drill Chart for Layer 1 to 8



Page 4 has the Drill table and Drill Chart for Layer 9 to 16


How it was done.





















I used three mechanical layers to display the via symbols above the drill charts.




Note the drill table is placed only once on the Drill Drawing Layer in the design.

Outjob setup for PDF Fab Drawing with three drill tables and charts.




Example for Layer 1 to 8 blind vias.










Choose the drill layers Start = L1 and Last = L8.





















Example for Layer 9 to 16 blind vias.












Choose the drill layers Start = L9 and Last = L16.




















That's It !
