Creating a Restricted Area 

This task shows you how to create a restricted area annotation.
  • A restricted area annotation allows user to define a delimited surface to be toleranced.
  • The restricting area and the restricted area may consist of several elements.
  • The surface may be defined using Generative Shape Design workbench.
  • To customize the restricted area options, see Display.
Open the Annotations_Part_11.CATPart document.

 

  1. Click Restricted Area  in the Geometry for 3D Annotations toolbar.

    The Restricted Area dialog box appears.

  2. Select the two restricted surfaces as shown on the part.

    • The Restricted Area field is updated, the Geometry Connection Management icon becomes available, see Managing Annotation Connections.
    • You can use the Connection Management to add/remove/replace/rename elements of the selection and manage the impacts of these modifications.
    • You can select as many elements as you want for each area, either from the specification tree or from the graphic area.
      Picking an element twice does not deselect it.

  3. Place your cursor in the Restricting Area field to validate the selection of the Restricted Area elements.

  4. Select the two restricting surfaces as shown on the part.

  5. Click OK to validate these selections and create the restricted area.

    The Restricted Area.1 is created in the specification tree and the restricted area appears with hatching lines on it.
    • To change the representation of the restricted area, right-click the Restricted Area.x node in the tree, select Properties and then Pattern tab. Alternatively, right click the restricted area to access its properties.

      From the Type list, you can select Dotting, Coloring, Image, or None and specify their required attributes.
      The pattern representation for the restricted area is displayed for planar surfaces only.
    • When a restricted area is not valid, a yellow filled circle is displayed on the icon in the specification tree.
      Right-click the restricted area in the specification tree and select Diagnostic Report from the contextual menu.
    • When the restricting elements are not included in the restricted elements, a message is displayed:
    • You can edit a restricted area:
      • double-click RestrictedArea.1 in the specification tree.
      • the Restricted Area dialog box is displayed.
      • you can only select the Connection Management icons or OK or Cancel.
      • Modifications made with the Connection Management cannot be undone.
    • You can filter the restricted area by applying 3D annotation filter. For more information, see Filtering Annotations.
    • In the 3D area, the restricted area is displayed even though the corresponding reference geometry is hidden.
