In some cases, the inputted curves are disordered as shown as the following picture, or the curves are contour curves. This type of curve can not be fitted to surface by traditional method like sweeping, skinnig or interpolation. So we developed Surface by curves for such type of curves.
curves The dialog panel for Surface by curves is similar to Surface by Nodes :
select curves
Import the demo file curves1.igs . Click the menu button Geometry->Surface->Fit from pnts/mesh . Select option Surface by Curves , select all the curves, then click button Preview , a surface shows.
previewed surface Output message is бо Control point #:u=10 v=11; max dev:0.216106, mean dev:0.041717 ' .
In order to get a better surface, you can change RefPlane direction, UV control point number setting or UV degree number and click button бо Preview ' to create a new surface.
If you want to increase the surface precision, set a smaller number in Max Tol text field and click button бо Fit '. The surface will be dragged to curves more closer.
