Profile question

so. If i have a callout Profile .010. No datums.

Does that mean that I will not have min and max? Since the surface has no basics and can shift in any direction???

so in another words when i measure it, i would only get one value, example .005 and total profile .010?

  • I was thinking of a overlay concept, where you have a perfect profile tollerance mylar and you overlay it over the part shape, and you can wigle it and move it around anywhere as long as the profile fits. In which case you can move so that the profile deviation will only be in one direction
  • Yes. A mylar is a great way to validate a "form only" profile, if it fits within the bounds, no matter how you must rotate or translate it, then it is good. The difference in the software is that the software has to start from somewhere. And where it starts from is 0. Everything else is (well, should be, there are some nuances) plus material.
