More About Recognizing Pockets or Pads

Several Possible Solutions
    Depending on the shape of the part, you will sometimes have to consider several possible solutions for recognizing pockets (or pads). This is the case of this part:
    There are two possible solutions for recognizing a pocket whose bottom face is green. You can either specify the blue face as the top face, or the yellow face as the top face.

Open the Pocket.CATPart document.

  1. Click the Manual Feature Recognition icon to display the Feature Recognition dialog box.

  2. Select the green face as the bottom face of the pocket.

  3. Click the Recognize Up to face field and select the yellow face as the top face for the pocket.

  4. Click OK to confirm and close the dialog box.
    A pocket feature has been recognized. The "Pocket.1" entity has been added to the specification tree, meaning that it is now possible to edit this feature. If you do not specify the limiting face you want, the application uses the face that is nearer to the bottom face as the top face. In our example, it would be the blue face.
 

Recognizing Pockets or Pads by Selecting Edges

Instead of selecting faces, you can select edges to recognize pockets or pads. This method lets you recognize a smaller region. To perform this scenario, use Solid2 in the Pocket.CATPart  document.

  1. Click the Manual Feature Recognition icon to display the Feature Recognition dialog box and check the Pocket option.

  2. Select the bottom face as the bottom face of the pocket.

    If you recognize the pocket, the simplified solid looks like this:

    In this case, the profile includes four elements only: two lines and two circular arcs.

  3. Now, instead of selecting the bottom face, replay the scenario and select the edge as shown:

  4. After recognizing the pocket, the simplified solid looks like this:

    In this case, the profile includes only one element, that is a circular arc.
  The colors defined for faces prior to the recognition process, are kept afterwards as illustrated in the above example.
  Both faces and edges cannot be selected at the same time, that is, if a face is selected, edge selection is disabled, and vice-versa.
