Trying to find a "simple" pattern to allow for me to pattern a set of holes drilled into the side of a cylinder. I have a continuous cam slot and I want the holes to line up normal to the cam follower as it travels along the cam slot (cam slot is a sine wave, and I want holes to be equidistant on either side of cam slot, as it goes around the circumference). I have successfully completed this by sketching points on a 3d sketch and drawing each hole individually, but it is extremely time consuming, messy and doesn't lend itself to being modified easily. A curve driven sketch is very close, but I can seem to get the "normal to" to work as I want it... Any ideas? Last two pictures are the desired end result, but I want a simpler way!
