its not automated procedure on cadstar like u find in other tools.Generate the drill report as suggested by "btbass", copy and paste the drill hole section in drill drawing layer as a text..problem is anytime,if any change is thr in drill count/size,u have to again copy/paste.
Also if u r ready to spend money,u can go for starturn (third part tool).it generates the drill report automatically
