WebAmongst the basic form controls (straightness, roundness, flatness & cylindricity), straightness is unique in that it can also apply to an axis, not just a surface. In these situations, the behaviour of the control is slightly different. Like flatness, straightness can also apply to a virtual feature – in this case a so-called “median line ...
