I need to create multiple hole patterns on a part. The pattern is three holes about a bolt circle of 2.5" in diameter. I want to be able to dimension to the center of the bolt circle for position and this pattern will occur 4 places on my part. It has been a few years since I have used SolidWorks and I need a refresher. I believe you need to create the first hole in the pattern as a radial hole and then pattern it. How do I go about creating a radial hole?
