Deforming The Surface Limits

Hide the three Curvature Analyses, using the Show/Hide contextual menu from the specification tree.

Choose the Top View icon from the View toolbar.

This will allow you to position the symmetry plane according to the current plane.

Select the surface you just created if needed and click the Control Points icon:

The Control Points dialog box is displayed.

Right-click the Symmetry Plane selection field and select the ZX Plane from the contextual menu.

Double-click the Symmetry icon to lock the functionality.

Choose the following deformation options from the dialog box:

Support: Mesh Lines Diffusion Law: Convex Law

Select the top front control point, then press and hold the Shift key then click the bottom front control point.

The whole front mesh line is selected.

Use the manipulators on one of the corner control points to bring it closer to the orange reference curve.

The mesh line takes the global shape of the reference curve, even though it does not match it perfectly yet.

Repeat this operation with the rear mesh line and reference curve.

From the Control Points dialog box, select new options: Diffusion Law: Constant Law

Select one of the side mesh lines and bring it closer to the orange reference curve till the patch corner reaches the curve end points.

You need to iterate on the front and rear mesh lines, using the same options to reach a satisfying level of superimposition.

For further tuning you need to zoom in and move single control points.

Select each patch corner point and move it exactly onto the reference corner point.

You need to move them along both X and Y.

Move each side control points to superimpose the patch boundaries and reference curves.

You need to move them along the Y direction only.

Move the inner control points 2 by 2, using the Shift key, to move them closer to the patch center.

The patch now has the shape given by the reference curves.

Click OK in the Control Points dialog box.
