FitFits the data base to the viewing area.
The Fit tool displayed above is used to rescale the view of the data base to fill the entire viewing area.
To use the Fit tool, select the tool by clicking it with the accept mouse button. Alternatively, in a Plan View double click the middle mouse button (the mouse wheel button).
The data base will then be redrawn at a suitable scale to fill the viewing area. That is, you will see the entire data base in the viewing area.
The Fit tool will then be automatically exited and control returned to the previously selected command.
