I'm struggling with the surface profile form and location option. For example, the print callout is profile of .03 to -B- with a BASIC dim of 18mm for location. Which means surface profile must fall in a zone of 18mm +/-.015 oriented and referenced to -B- datum. When I use surface profile form and location I get 0 for a nominal and basically the same results if I were to use parallel. What’s up with that? The help file example shows a nominal and measured of 5.000.
