I'd like to know if there is a way to create a single sketch to specify the locations of hole wizard holes in multiple parts used in an assembly. I have a series of parts that stack on threaded rod. The hole pattern is only loosely defined at the moment and I'd like to model as much as I can in order to make progress. When I get the final specifications, I'd like to update one sketch and have all of the parts update. Any way to do this easily?
