Use PAN command or use the window scroll bars to shift the location of your view.
With the Realtime option of PAN, you pan dynamically by moving your pointing device. Like panning with a camera, PAN does not change the location or magnification of objects on your drawing; it changes only the view. By right-clicking, you can display a shortcut menu with additional viewing options.
You can move the view of a drawing displayed in the current viewport by scrolling, panning, or rotating the view. Doing this changes the portion of the drawing you are viewing without changing the current magnification. Scrolling lets you move around in the drawing horizontally and vertically. Panning lets you move the drawing in any direction. Rotating lets you view your drawing from any angle.
Using scroll bars
To assist you in navigating within a drawing, horizontal and vertical scroll bars are available in each drawing window. The size of the scroll box in relation to the scroll bar indicates the current level of drawing magnification. The position of the scroll box in relation to the scroll bar indicates the location of the center of the drawing in relation to the extents of the drawing (the smallest rectangle containing all the entities in the drawing).
To turn scroll bars on or off
Do one of the following:
Choose View >Display > Scroll Bars.
Choose Tools > Options > Display tab, and select Display Scroll Bars in drawing window.
Command line SCROLLBAR
Using the Pan command
You can move the drawing in any direction using the pan command. Panning shifts or slides the view of the drawing horizontally, vertically, or diagonally. The magnification of the drawing remains the same, as does its orientation in space. The only change is the portion of the drawing displayed.
To pan, you can use any of the following methods:
For precise panning, specify two points defining the magnitude and direction of the pan.The first point, or base point, indicates the starting point of the pan. The second point indicates the amount of pan displacement relative to the first point.
To pan in real time, press Ctrl + Hold and drag right mouse button, or use the Pan Realtime tool on the standard toolbar.
If you have a mouse with a wheel, press and hold the wheel, and then move the mouse.
To pan in real time
Choose View > Zoom > Realtime.
Move the cursor in the direction you want to pan.
To stop panning, press Enter or right click the mouse to choose edit.
Command line PAN
TIP Hold down the right mouse button while simultaneously pressing and holding Ctrl to pan in real time.
