After making adjustments and closing the window, you can rotate the view to see the interior construction of 3D objects as they pass in and out of the clipping planes.
The following options are available from the window toolbar or the context menu
Adjusts only the front clipping plane. The line near the bottom of the window adjusts the front clipping plane. If a check mark is displayed next to Front Clipping On, you can see the clipping in the 3D Orbit view as you move the line up or down.
Adjusts only the back clipping plane. The line near the top of the window adjusts the back clipping plane. If a check mark is displayed next to Back Clipping On, you can see the clipping in the 3D Orbit view as you move the line up or down.
Causes the back and front clipping planes to move together, which shows you a “slice” of the objects in the 3D Orbit view. Adjust the front and back clipping planes, and then choose Create Slice. You can then move the front and back clipping planes as one unit.
Displays the pan cursor, a hand cursor that you can use to pan the clipping plane. Hold down the pick button and drag the cursor in any direction. The pan cursor stays active until you click another button.
i Displays the zoom cursor, a magnifying-glass cursor that you can use to enlarge or reduce the clipping plane. To enlarge the image, hold down the pick button and drag the cursor toward the top of Adjust Clipping Planes window. To reduce the image, hold down the pick button and drag the cursor toward the bottom of the window.
Turns the front clipping plane on or off. A check mark indicates that the front clipping plane is on, and you can see the results of moving the line that adjusts the front clipping plane. Choose this option again to turn the front clipping plane off and remove the check mark.
Turns the back clipping plane on or off. A check mark indicates that the back clipping plane is on, and you can see the results of moving the line that adjusts the back clipping plane. Choose this option again to turn the back clipping plane off and remove the check mark.
(Context menu only) Resets the window and clipping plane to the extents of the drawing.
