Managing Open Bodies 
in the Specification Tree

This task shows how to manage the specification tree. This involves;
inserting open body entities
removing open body entities
changing body
An open body enables to reorganize the specification tree when it becomes too complex or too long. You can put any element you wish in the open body, it does not have to be structured in a logical way.
You can insert and manipulate open bodies in the specification tree in much the same way as you manage files in folders.
These management functions have no impact on the part geometry.
You should refer to the Copying and Pasting section for information about how open bodies can be used in a part edition context.
When loading the Generative Shape Design workbench, an Open Body automatically becomes the current body. 
This also means that only the results of the Part Body, i.e. the result of all the operations performed on geometry, is visible and not any intermediate state of the Part Body.
Open any .CATPart document containing OpenBodies.
You can also open the OpenBodies1.CATPart document.

Inserting an Open Body

  1. In the specification tree, select the branch of your choice. 
    This branch will be considered as a child of the new open body and can be an open body or a feature.

  1. Select the Insert -> Open Body menu command.

The result is immediate. CATIA displays this new Open_body.x, incrementing its name in relation to the pre-existing bodies, in the specification tree. It is underlined, indicating that it is the active open body.

Removing an Open Body

This is only possible when the father location of the open body is another open body.

  1. Right-click the desired open body then select the Remove Open Body contextual command.
    The open body is removed and its constituent entities are included in the father open body.

Moving an open body to a new body

  1. Right-click the desired open body in the specification tree and select the Change Body command from the contextual menu.
    The Change Body dialog box appears.

  1. Select the new body where the open body is to be located.

  2. Click OK to move the open body to the new body.
