This is a challenge for us as well and we are trying to find the most realistic approach that defines the product without having to create many cross sections to define complex geometry areas.

Now the question is, how do you measure it and how do you document it was done correctly when approving the drawings? Some have suggested using GD&T which has a Surface call out that will let you point to a complex surface and state that surface must be within a particular tolerance range of that shape to be acceptable. If the drawing is approved and has a signature, how do you determine if all dimensions were looked at when the decision was made? If the drawing does not contain all the dimensions to define the product, how do you insure the model was analysed during the approval process? When you are dealing with complex geometry, it is difficult to fully dimension the drawings which poses a problem in some cases. In some cases our drawings are the only documentation we can send to production and in other cases we can send the model and the parts are made by CNC.
