How to Select Multiple Objects

In the FEA Editor environment, you may want to select multiple objects (i.e., parts, surfaces or vertices) in order to specify constraints, loads, element information, material information or other finite element data. You can conveniently select multiple objects by using the <Ctrl> key.

Once you have selected one object, you can then press and hold the <Ctrl> key and select another object to add it to the current selection set. Any selection shape (i.e., point, rectangle, circle or polyline) can be used with the <Ctrl> key.

For example, the figures below show how to select multiple surfaces of a bearing assembly model in order to apply a pressure load.

Figure 1: In the FEA Editor environment, after using the "Selection:Shape:Point" command sequence to specify point select mode and "Selection:Select:Surfaces" to specify surface select mode, a mouse click is used to select one of the surfaces.	Figure 2: While pressing and holding the <Ctrl> key, a second mouse click adds another surface to the selection set.

Thus, the FEA Editor environment's capability to select multiple objects with the <Ctrl> key provides convenience and flexibility, which helps you to quickly and easily specify model data. The <Ctrl> key also enables you to select multiple objects in the CAD Solid Model and Superview IV environments.
