Hello,
I had a similar problem: I could not define the tool for aggregate drilling in the Alphacam program. I solved the problem like this: I looked at how many pieces there were in the x and y alignment of the drill. For example, the aggregate is 5 pieces on the x-axis and the axis spacing is 20mm, and the aggregate is 3 pieces on the y-axis and the axis spacing is 10mm. I drew the holes in these features. Then, I made that hole a different color depending on the exact center of this hole, or whichever drill I wanted to start drilling. Then, I reproduced my aggregate drawing group by group on my plate. I programmed only the colored holes. This way I solved the problem temporarily.
