Dynamic View Controls

When your current window is a graphical model view, you can use the mouse wheel to dynamically zoom, pan or rotate the graphical image.

Mouse Action	Model View Function
Roll the Wheel Forward	Zoom in
Roll the Wheel Backward	Zoom out
Click and hold the Wheel Button	Grab the image and pan in the direction of mouse movement
Click and hold the Wheel button while pressing the Shift key	Dynamically rotate the structure in the direction of mouse movement

The following table describes how to use the mouse to perform specific tasks.

Task	What to do
Dynamic Pan	Click and hold the mouse wheel button to trigger the Dynamic Pan feature, which allows you to pan or drag the view to the limit of the scroll bars.
Dynamic Zoom	Rotate the mouse wheel button forward to zoom in and backward to zoom out.
Dynamic Rotate	Click and hold the mouse button while holding the Shift key down to trigger this feature. The rotational movement is based on how you drag the mouse cursor over the screen and the projection of global axes on the screen. For rotation about X axis, drag the cursor perpendicular to the projection of the global X axis. The same logic applies for Y or Z axis rotations. When rotation is initiated, the system locks for rotation about that axis until you release the middle mouse button.
Zoom Previous/Next	The F3 and F4 function keys are associated with Zoom Previous and Zoom Next, respectively. The system holds a doubly linked list of zoom info. This list has 10 zoom-states in the list. Press the F3 or F4 key to move the active pointer forward or backward on the list. Each window has its own zoom list.
Dynamic Distance Tool	Press the F5 function key to trigger the Dynamic Distance Tool, then select two points on the screen. On the status bar, the system displays the total and partial distance between the points.
