INFO

Points

 

The Info->Points command is available in all modules except Tools. It displays information about all points in a curve, surface, polygon mesh, or face and allows you to modify points numerically. However, there is no visual feedback as to which point on your object corresponds to the point selected in the scroll box.

Coordinates values for selected points can also be modified using Edit->Coordinate. Using that selection, there is onscreen feedback as to which point is selected.

Procedure

  1. Select an object.
  2. Choose the Info->Points command.

    The Info Points dialogue box is displayed:

    For Faces, see Faces and Bezier Curves; for Bezier curves, see Curve Info (Bezier).
  3. Select Local or Global Coordinates to see where the points are in relation to the object or the origin.
  4. Select the point you want to modify from the scroll box.
  5. The point number coordinates are displayed in the modification boxes at the bottom of the dialogue box.
  6. Modify the X, Y, or Z coordinates as desired. In the case of points of a NURBS curve or surface, the fourth parameter, W (Weight), can also be modified. For other curve types, the value for W is always 1.0 and cannot be modified.
  7. Click Modify to update the point coordinates.
  8. Repeat steps 4 to 6 for other points, as desired.
  9. Click Ok to confirm all modifications or Cancel to exit without accepting changes.

Parameters

Type

Type of object, such as patch, polygon mesh, curve, and so on.

Name

Object's name.

Local Coordinates

Displays the coordinates in the scroll box according to the object centre.

Global Coordinates

Displays coordinates in the scroll box according to the origin (global centre).

Scroll Box

List all points by number with their associated X, Y, and Z coordinates. For a NURBS curve, a fourth parameter, W (Weight) is also displayed.

Modification Boxes

Displays the current point number and allows you to edit the X, Y, Z coordinates. For NURBS, you can also modify the value for W (Weight). For other curve types, the value for w is always 1.0 and cannot be modified.

No. Points

Number of points on the object.

Modify

Confirms the modification but keeps the dialogue box open.

Faces and Bezier Curves

If you select a face or a Bezier curve, a different dialogue box is displayed. If you select a face, the Face Points dialogue box is displayed. From this dialogue box, you can choose to edit points on its exterior contour, or points for a hole. When you click the Edit button, the Info Points or the appropriate curve information dialogue box is displayed and you can edit the points as desired.

If you select a Bezier curve, the Curve Info (Bezier) dialogue box is displayed. For more information, see Curve Info (Bezier).
