Open the Symbols bar if it is not already open by clicking Symbols.
The Symbols bar provides object symbols, graphic objects, and text for insertion into the modeling area. It also allows you to filter the available object symbols by entering names and create connections between objects.
Click the object symbol you want to place and hold down the mouse button.
Drag the preview frame between the objects where you want to place the object. If you have enabled Guided Modeling, lines and arrows inform you of the orientation and distance of the dragged object from adjacent items. The connection on which the preview frame is placed is highlighted in green.
Release the mouse button. The object is placed, the lower objects are moved, and the connections are newly linked. The name of the new object is selected for renaming.
Enter a name. If you enter an existing name, existing objects are offered for selection. You can create a new object, select an existing one, or create a new one with the same name.
