Create a curve from series of theoretical points.

I was looking at your picture again - what is the reason for using curve? Wouldn't be enough using 3d line?

Technically yes. However, from my understanding, curves and 3D lines offer different insights. One significant aspect is the graphical representation. We end up outputting these points to Excel to produce a 2d graph. I was hoping to use a 2d curve to get the graph. With a 3d line, the best graphical option would be straightness, which only controls form, and the graphics do not offer the same insight. Also, and more importantly, is there not a fitting process that CALYPSO uses when recalling to 3d line? It will create the best-fitting line for those points, and in a sense, it will somewhat ignore the nominal points. Especially when outputting to straightness, since only form is restricted.  Whereas the curve will output the deviation relative to those specific nominal points.

I think you can use "Form" to see devations on 3d line with restricting settings.
