Removing Bodies

This tasks illustrates how to remove a body from another body.

When working in a CATProduct document, it is no longer necessary to copy and paste the bodies belonging to distinct parts before associating them. You can directly associate these bodies using the same steps as described in this task.

Open the Remove1.CATPart document.

The part is composed of two bodies. To remove Body.1 from Part Body, select Body.1.

Removing a set of bodies (multi-selected via the Ctrl key) is possible. This capability will increase your productivity.

Click the Remove... icon .

The result is immediate. However, if the specification tree is composed of several bodies, a dialog box displays to let you determine the second body you wish to use. By default, the application proposes to remove the selected body from Part Body.

The cylinder is removed from Part Body:

You cannot re-apply the Assemble, Add, Trim, Intersect, Remove and Remove Lump commands to bodies already associated to other bodies. However, if you copy and paste the result of such operations elsewhere in the tree you can then use these commands.

Avoid using input elements that are tangent to each other since this may result in geometric instabilities in the tangency zone.

Structuring Your Design

Generally speaking, using Boolean Operations is a good way of structuring your part. Prior to designing, you can actually define the part's structure by associating a body containing geometry with empty bodies. Once these specifications are done, you can then concentrate on the geometry.
