Using the FreeStyle Optimizer

The FreeStyle Optimizer offers complementary capabilities to the FreeStyle Shaper. It is used on the same type of elements yet taking the design capabilities one step further.

Fit a curve to a cloud of points: select the curve to be deformed and the target element, specify the fitting parameters and, if needed, the continuity constraints using the contextual menu, click Fit then OK.
Fit a surface to a cloud of points: Select the surface to be deformed and the target element, specify the fitting parameters and, if needed, the edge constraints using the contextual menu, click Fit then OK.
Globally deform a surface: Select a set of surfaces, if needed select the guiding curve, click Run, specify the deformation type and use the control points and mesh lines to deform the surface. 
Analyze reflect curves: Select a surface, specify the neons grid parameters (number, spacing, position, viewpoint.), manipulate the grid to analyze its reflection on the selected surface.
Analyze inflection lines: select a surface, set the compass orientation and click the icon to visualize inflection lines
