Using the preview

A preview of the selected document is displayed in the preview area. In this view, you can zoom, pan and select isometric views. Click Preview on the View menu to specify whether and where the preview is placed.

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

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