Using the CNC to drill holes along a specified path

Here are 12 three-millimeter cylinders at a five-millimeter spacing along a spline as an example of what @nivekmai suggested. I created a sketch, added the spline, then placed a center-diameter circle at the start point of the spline. Then I finished sketch and extruded the cylinder. After making the sketch visible again, from create, pattern > pattern on path, select the face (or body), then the path from the sketch. Distance can be a total distance (e.g., x number over x distance) or spaced as in my example.
