Using the preview

You can see the selected document in the preview. You can zoom in on the preview, pan the preview and display the preview in isometric view. Click Preview on the View menu to specify whether and where to place the preview.

To turn off the preview, point to Preview on the View menu and click None.
To zoom in on the preview, open a selection rectangle around the area you want to view in detail. The cursor changes to crosshairs.
To pan the preview, move the view with the middle mouse button. The cursor changes to a hand. Alternatively, use the cursor keys.
To restore the preview to full view, double-click the middle mouse button in the preview area or select the * key on the numeric keypad.
To display an isometric view, use the number keys on the numeric keypad. Check that the Num Lock key and the preview are selected as you do so.

Note: The preview is only available with certain documents (drawing files, layouts).
