Creating a Bounding Box

This task explains how to create an associative bounding box around a shape, that lets you modify either the shape or the axis system.
You must have a molded part in the workbench.
Go to Tools > Options > Infrastructure > Part Infrastructure > Display and select Parameters under Display in Specification Tree

  1. Open FilterCover.CATPart in the samples/import directory.

  2. Click Bounding Box in the Models toolbar.
    The Create Bounding Box dialog box is displayed.

  3. Select a shape and an axis system.
    A bounding box is displayed around the shape.
    The dialog box is updated.

  • The shape must be connex, with no undercut.
  • Only direct unit axis systems are supported.
 

  1. Select the type of the bounding box.
    By default, the type is set to Box.

    • Box:
    • Cylinder:

  2. If necessary, use the manipulators of the bounding box or the spinners of the dialog box to define offset planes.
    The Bounding Box Size is updated automatically.
  • Negative offset planes are supported.
  • When the bounding box is a cylinder, X Length and Y Length correspond to the diameter of the cylinder.
 

  1. Click OK to validate and exit the dialog box.
    The bounding box is created:

    • A pad is created in the Bounding Box.1 body,
    • The standard features and parameters are created (respectively in Bounding Box Elements.1 and Parameters bodies) and are editable.
