Removing Volumes

This task illustrates how to remove a volume from another volume.
Open the RemoveVolume1.CATPart document.
  This is your initial data: the Remove part is composed of two geometrical sets.

  1. Click Remove from the Volumes operations sub-toolbar.

    The Remove dialog box opens.
  2. Select the volume to remove (CloseSurface.1) in the Base object field.

  3. Select the volume from which it is removed (CloseSurface.2) in the Removed operand field.

  4. Select a destination body after which the removed volume will be located.

    If the Geometrical Set or the Ordered Geometrical Set is current, the After field is valuated with the current body and will be located after its last feature.
  5. Click Preview to visualize the removed volume.

  6. Click OK.

    The operation (identified as is added to the specification tree.
    The specification tree and the Remove part now look like this:
    • You can now edit a Remove feature and modify the volume from which the volume is removed. To do so, simply double-click the feature in the specification tree and select a new volume in the Removed operand field.
    • Adding a body to a solid body and vice versa is possible. In that case, the second body you select remains at the same location in the specification tree once the Boolean operation is done. To see an example, refer to Mixed Boolean Operations.
    • Multi-selection is not possible.
    • Avoid using input elements that are tangent to each other since this may result in geometric instabilities in the tangency zone.
