Grouping Bodies

	Grouping elements allows you to generate images from a group of elements (points, lines, surfaces, bodies). This capability is only available if you installed the ELFINI Structural Analysis product.
	This task shows how to group bodies and how to generate images from this group.
	You can use the sample49.CATAnalysis document from the samples directory for this task. Before You Begin Go to `View -> Render Style -> Customize View` and make sure the `Shading, Outlines` and `Materials` options are active in the Custom View Modes dialog box.
	1. Click the Body Group icon . The Body Group dialog box appears. 2. Select in sequence the bodies you want to group. The Body Group dialog box is updated. 3. Click OK in the Body Group dialog box. A `Body Group.1` object appears in the specification tree but it is not updated. 4. Update the Body Group. For this, right-click the `Body Group.1` object in the specification tree and select `Update Group`. The symbol disappears in the specification tree. You can now visualize Deformation, Von Mises Stresses, Displacements, Principal Stresses and Precisions images, either for all the geometry or only for the selected points. The scenario is the same for the five images. In this particular case, you will visualize the Von Mises Stresses image: 5. Activate the Von Mises Stress image. For this, right-click the `Von Mises Stress (nodal value)` object in the specification tree and select the `Activate/Deactivate` option. 6. Double-click the `Von Mises Stress (nodal value)` object in the specification tree. The Image Edition dialog box appears. 7. Click the `Body Group.1` object in the Selections tab. You will see the result only around the selected points. For more details about Images, see Results Visualization (Image Creation, Generate Images and Editing Images).
	You can manually edit or delete a group. For this, right-click the Group object in the specification tree and select the desired option in the contextual menu.
