Initial Fairing

Having created the initial definition as described above, the user should review the current design as a whole, it may be necessary to refine the FOB and FOS curves or modify some of the stored sections. This can be done by selecting the curves in the Curve tree and clicking the Patch and Curve Editor (PACE) button, . Alternatively, click the PACE button from the Edit toolbar, , select the required curves from a Graphics Window and then click the Right Mouse button.

A few preliminary waterlines or buttocks may be interpolated from the stored sections. The Fairing dialog can be used to either get individual waterlines or buttocks or to fit a specified range. The Sections check box in the Interpolation panel must be selected.

These can be used to assess the fairness of the design. The objective at this stage is not to introduce too much data as the more data you have the more difficult it becomes to manipulate.

At this point the user has two options, either proceed with the traditional approach or use the 3D fairing method. Both are described in the following sections.
