2.4.2 Selecting objects
Selection is another important aspect for interacting with the model. Selection requires a selection context, which tells FEBioStudio what type of entity you would like to select. The current selection context is highlighted on the toolbar and can be changed by clicking on the corresponding selection button. For instance, to select an object, first click the “Select Object” button on the main toolbar (i.e. the button with the green ball). With the button selected, you can now select any object in the model by clicking on it with the left mouse button. Selecting another object will automatically unselect the first selected object. To add an object to the current selection, hold down the shift key when you select the object. Similarly, you can remove an object from the current selection by holding down the ctrl key when clicking on the object.
To select several objects with one motion, first choose a selection method from the main toolbar. There are three selection methods: rectangle, circle, and free form. For example, select the rectangle selection method. Now, hold down the shift key and then click and hold down the left mouse button on an empty part of the screen. With the shift key and left mouse button down, drag the mouse to draw a rectangle around the objects you wish the select. Once you let go of the left mouse button, all objects that are inside or intersect the rectangle will be selected. You can also use this procedure to unselect several objects at once. Just repeat the procedure but hold down the ctrl key instead of the shift key. The other selection methods work similarly.
