Using Edition for Modification

This task shows you how to use the edition command and impose numerical values by means of a grid.
This capability is available when performing a transformation (translation, rotation, affinity or weight).

A sphere has been created.
You can also open the Symmetry2.CATPart document.

  1. Click Modification .

  2. Select one of the transformation commands.

  3. Click the sphere.

  4. Click Edition .

  5. Set the desired values.

    • : the grid is used to input the position of the axis. X, Y, and Z define the coordinates of this position.
      The Translation dialog box opens.
    The following icons enable you to:
    • (Compass Translation) translate the compass according to the selected vertices.

    • (Coordinates Alignment) align the selected vertices according to X, Y, or Z coordinates. When activated, the Compass at the Origin icon is unavailable.
      In our example, we are going to align all the selected vertices along the y coordinates:
      Here is the result:
    • (Compass at the Origin) reset the current compass position and centers the subdivision surface to the origin (provided View centered is checked in Tools > Options. Refer to General Settings for more information).

    See Translating a Surface.
    • : the grid is used to impose the rotation angle.
      The Rotation dialog box opens. Click Preview to visualize the modifications.

    See Rotating a Surface.
    • : the grid is used to impose the dimension of the bounding box view.
      The Affinity dialog box opens.
    See Scaling a Surface.
    • : the grid is used to adjust the weight applied to edges or vertices.
      The Weight dialog box opens.
    See Modifying Vertices or Edges Weight.
  6. Click OK to validate the new values.
