Refit Original Sections

The original 3D curves should now be switched off and the original sections fitted to the new 3D curves to assess the fairing. If the results are not acceptable the user should re-fair the original 3D curves where necessary and re-fit the sections again.

If the sections are acceptable then the user should interpolate a closely spaced range of sections. This will indicate which areas require further control. The user should then introduce localized 3D curves in these regions and fair them. Usually it is best to introduce the localized curves as Plines.
