How can you gather faster the holes and group them on diameters when working on a .STP model. The only method I found was to first draw the axes for each hole, make the first drilling sequence for the tip and group the holes on sets. Then I could choose in the next sequences the previous set. The BIG problem is when I receive big plates with 150- 200 holes with different diameters (from 2 to 20 mm ). And all mixed up on the surface. It takes hours to get those drilled in sequences. So , if anyone knows a better faster way please share. I'm usin Pro E 4.
