This task shows you how to create holes in the main shape by using the Protected Feature capability. You will create three protected prisms, that is areas within which no additional material created by other features within the same body can be added.

 

 

  1. Click the Protected Feature icon .
    The Protected Feature dialog box that appears displays the Prism icon as the default shape to be created. Keep this option.

  2. Select Key holes as the profile to be used.

  3. Enter 20mm in the First length field.

  4. Click the Direction tab to ensure that the direction of the features will be normal to the profile plane.

  5. As you do not need to draft the feature nor fillet its edges, simply click OK to create the protected prism.

  7. Select HP Holes as the profile to be used.

    Third Protected Prism

    Now you will create a third protected prism that corresponds to the area reserved for the phone electronic mechanism.

  11. Select Reserved Space as the profile to be used.

  12. Enter 4mm in the First length field.

  13. Enter 2mm in the Second length field.

  14. Click the Draft tab.

In a Nutshell

Creating a protected volume:

  • generates no walls.
  • material created by other features within the same body will not penetrate the protected volume.
