Defining a Cavity

This task explains how to define a cavity on an electrical device.
The cavity is used to specify the location of the electrical object when connecting.
Open any document containing an item of equipment where you want to place a cavity.

  1. Click Define Cavity .

    The Cavity Definition dialog box opens:
  2. Select the equipment where you want the cavity to be defined.

  3. Change/enter a value in the IdNumber field.
    Note that the IdNumber must be unique.

  4. Select a Representation, for example a pocket, a pad, a face...

  5. Optionally, place a Contact constraint, for example a surface or a point.

  6. Optionally, place a Coincidence constraint, for example a surface, a line or an axis.

  7. Optionally, place an Orientation constraint, for example a surface, a line or an axis.
    The orientation is used to constrain the rotation i.e. the third degree of liberty.

  8. Click OK  to validate.

    The specification tree is updated.

For more information about the placement constraints, refer to Using Assembly Constraints.

A cavity is allowed on equipment.
