3.6 The Graphics View
The Graphics View shows a 3D view of the current model. The user can adjust the view in several ways. The fastest way of maneuvering through the view is by using the mouse. The different mouse buttons invoke different commands depending on the current mode of the Graphics View. There are four buttons on the Toolbar that control this mode, namely the select, move, rotate and scale buttons. The current mode is indicated by the button that is highlighted.
Regardless of the Graphics view mode, the view can be rotated by dragging the mouse button outside any geometry while holding down the left mouse button. A similar action but with the right mouse button down allows the user to zoom the view. The user can pan the current view by holding down the middle mouse button. Objects and items can be selected in all four Graphics view modes. To select an object or item (e.g. part, surface, edge), bring the mouse cursor over the object or item, and click on it with the left mouse button. To add objects or items to the current selection, hold down the shift button while clicking on the object or item. To add several objects or items, drag the mouse while holding down the shift button and left mouse button. To deselect objects or items, the same operations can be performed, only this time, hold down the ctrl button instead of the shift button. To deselect all objects or items at once, click in an empty area of the Graphics View. There are also several menu items that allow you to modify the current selection. See section 3.2.1↑ for more information.
By default, FEBio Studio renders the model using perspective projection in the Graphics View. By right-clicking with the mouse button a popup menu shows up under the cursor that allows the user to toggle between perspective and orthographic projection. In addition, this menu provides some buttons that allows the user to quickly orient the geometry along one of the three coordinate axes.
When the Graphics View is in one of three transform modes (move, rotate or scale) a triad will appear in the center of the selection. When moving the mouse over the triad, one of its arms may highlight, indicating that this arm can be selected. To apply a transformation to the current selection, bring the mouse cursor over one of the triad arms so that it highlights. Next, drag the mouse button while holding down the left mouse button. Releasing the left mouse button will let go of the arm and finish the transformation.
