I’m a newbie and I’m looking for the easiest way to place a series of same sized grooves on a shaft where the grooves are not equally spaced apart.  Ideally each individual groove would be located a specific distance from the end of the shaft. Currently I’m creating work planes for each groove and extruding the groove at each plane. There’s got to be an easier way. I tried a linear array but I can’t delete the original groove afterward and still retain the array. Any suggestions?
