I am drilling a quite a few holes in a plate that is 20' long. The plate will have 3 different size holes and one size needs a countersink. The problem I am having is Bobcad is always starting the first hole for each size drill at the far left end of the plate and working its way to the right. When one drill is finished and the spindle is positioned at the far right of the plate it changes tools and rapids 20' back to the left most hole for the next drill. Is there any way to reverse the order of the drill cycle. Also, the hole with the chamfer is set up in the same feature. It also wants to drill the hole from left to right then change tools to the countersink and rapid back to the left before starting the first chamfer.

Are you using V23?

In V23 there is a Posting parameter that allows for "output Pick order" or "Output Optimized". The optimized would try to eliminate this.

When using the Composite drilling operations, the order of the points is the same for every operation. The system is not aware of the tool change location, so it can't optimize from the tool change.

You can do what you are asking, but it requires a little mo0re effort:

You would have to first modify the Tool Patterns for the drilling operations and take them down to one op per feature.

Then you would have to create two sets of points, or use the manual selection method (which in your case is not likely to be helpful). You would then use the two sets in an alternating fashion between features.
