Recently I had to create some scal reference for a presentation and I thought I would share them with my fellow Creoittes.
These are Creo 2 models with X, Y and Z grads centered at the origin. one has one inch majors and the other has millimeters with major grads at 1 centimeter. Both have patterns that allow for as many grads as you want. Play with them a bit...it will make sense.
