Control Points Dialog Box

The Control Point dialog box appears when you select Control Points in Modify section.

This page discusses:

Global

  • Global Mesh Mode: Allows you to modify all the selected meshes at the same time, in the case of multiselection. With this option selected, the rows of control points propagate to the neighboring mesh if a contact is found between them.
    Note: This option is available if Mesh only is selected and the continuity at the common end point or the common edge is Free (F).

Projection

  • Project along the Robot normal: Projects the selected control points along the Robot normal direction.

  • Project along in the Robot plane: Projects the selected control points in the Robot plane.

Harmonization

  • Harmonize: Computes the harmonization of the selected control points deformation according to the selected law.
  • Four options are available:
    • Blend: Aligns the internal control points imposed by the external control point rows. It creates a smooth transition between each control point row. Using this option, internal control points are no more manipulable, as their position is imposed by external ones.
    • Mean Plane: Computes a mean plane defined by three points. The first point of the current manipulated row, the end point of this latter and the barycenter of all the points of this row. If all the control points of the row were not already coplanar, they are projected onto this means plane. This plane automatically recomputes each time a control point moves.
    • 3-point plane: This option is similar to the Mean Plane option, but the mean plane is computed using the manipulated point, instead of the barycenter. As a result, when the row is projected onto this plane, the point is constrained to move along the direction defined by the intersection of the plane containing its U row, and the plane containing its V row.
    • Screen Plane: Aligns control points according to a plane parallel to the screen plane.

Options

  • Display Inflections: Allows you to display arrows at the control points representing their normal vectors and deduces the inflection at the control point locations. These arrows display when the surface is not locally planar at the considered control points and when the control points are connected to three mesh lines at least.
  • Display Deviations: Allows you to display the maximum deviation between the current shape deformation and the original shape for the selected element (point or mesh). When you select several elements, the deviation only displays for the modified element. The maximum deviation displays on the shape and in the dialog box.
  • Display Harmonization Planes: Allows to you to display the planes computed according to the harmonization law. This option is only available with Mean plane or 3-Points plane options of Harmonization.

Smooth

  • Smooth: Smoothes a curve or surface according to a smoothing factor between 0 and 1. The default smoothing factor is 0.5.

Display

  • Deviation: Displays the maximum deviation when Display Deviations is selected.
  • Element: Displays the number of geometric elements in use, and the ratio-selected control points/existing control points.
