Zooming and panning

Zooming in and out

There are three methods of zooming in and out:

• The mouse wheel zooms the screen at any time.

• Use the zoom buttons on the toolbar.

• Use the <Page Up> and <Page Down> keys on the keyboard.
  

Panning

• Use the keyboard arrow keys to pan the screen at any time.

• If you are in 'drag' mode (i.e. the toolbar button is selected) holding down the left mouse button and moving the mouse will drag the drawing.

Rotating the screen in 3D

You have to be in 'drag' mode (i.e. the  toolbar button is selected) to rotate the screen. Hold down the <Shift> key and move the mouse to rotate the drawing.

Drag mode

If the pointer button  is selected then you will automatically be in drag mode as soon as you press a mouse button. Holding down the <Shift> key will enable drag mode while any other selection tool is active. The mouse pointer will change into a hand to show you are in drag mode. On releasing the <Shift> key the previous selection tool will be reactivated.
