Guys, I recommend Cambam to someone a month ago, he was struggling with Autodesk + Catia (I don't know why he had to manually add some gcode in every program generated by Catia, he was generating a separate program for every operation

)
Since then he uses only Cambam, everything is so easy for him now, but yesterday he came by and told me that there is only one thing that he would need, a way to select the same diameter holes automatically, as his drawing always contains ~50 holes made with a 3mm drill, another ~50 made with a 6mm drill.
I searched in the plugins section and found this thread, I was sure there should be a plugin already made for this, and it was !!!

I just wanted to thank you again for this awesome program, and the great community! Well done guys! Congrats'!
