Has anyone came across this yet? Is this actually callout out the form of the trim line? My experience is that the arrow always pointed to the surface to be controlled. In this case I would report the trim deviation only. Plus I have never been able to pull the surface data of edge points for a profile evaluation. Just figured I ask to gather other opinions.
yes 3 <--> 4 refers to a start to end point or between points of the surface. looks like a profile of a line on the print not surface like the control frame has?

looks to me like a LAZY designer didn't want to put TWO callouts on there so he put a note on that it applies to both the surface and the trim from point 3 to point 4.
The TRIM & FORM is comment is what threw me off. There are two like this while there are two others with one stating FORM & the other stating just TRIM. Now that I am looking at the drawing more, there is another profile for the form in this area. I just don't believe the engineers want both trim & surface lumped into one dimension.
NOT into one dimension, but just to the same tolerance. My guess is that is a weld edge, so the surface needs to be 'close' and the trim needs to be 'close'.
