Zoom Command

This command combines two functions:

Enlarge a selected screen area (Window)

The desired area is defined with the cursor. Move the screen cursor to one corner of the required area. Click and hold the left hand mouse button and drag the cursor to a diagonally opposite corner. When you release the button the selected area will be redrawn so as to completely fill the screen area.

Display complete screen contents (Zoom all)

Move the cursor into the graphic screen at any position and click with the left hand mouse button. The complete screen contents will be re-drawn and scaled so that they are all just enclosed by the screen.

Zoom by Mouse Wheel

Rotating the mouse wheel zooms in and out the view by setting the cursor position as the zoom center. This makes it possible to quickly move around the model, without the need to Pan.
