In the graphics window, click and drag the zoom indicator down the screen to zoom in on the extrusion. Note: If your system zooms out when you drag down, it is likely that this option was selected during installation. You can easily change the zoom direction of the drag and mouse wheel (at any time): on the Display tab of the Application Options dialog box select the Reverse direction option. If you have been using AutoCAD for some time you may be more comfortable using the AutoCAD zoom direction preferences.
