I have a curved fastening flange with equally-spaced rivet holes, which was created using the hole wizard and a curve-driven pattern with equal spacing turned on.
The curve-driven pattern feature has the option of dimensioned spacing, however when using the "equal spacing" option, there doesn't appear to be a way to measure the arc length between nodes along the surface.
All holes are designed to go through normal to surface, rather than orthographically projected from X plane.
In the factory, the operator will be measuring from hole to hole to ensure consistent spacing between them, and dimensioned from each terminating edge.
What is the correct way to dimension the spacing between holes normal to a curved surface in a drawing? In orthographic views, the holes appear to get closer together and the dimension shrinks as the surface sweeps away from the view and approaches tangent. The design intent is for all the holes to be spaced evenly along the surface.
