In CAD, it is advisable to always draw at 1:1 scale. In order to get the desirable precision, zooming and panning while drawing or consulting is a continuous task. Having a wheel mouse or other advanced input device with scroll functionality, zooming and panning are a straightforward process. With a wheel mouse we can:
- Zoom in/zoom out: Rotating the wheel forward we zoom in, we see more detail. Rotating the wheel backward we zoom out, we see less detail and more of our model.
- Zoom fit: With a quick double-click on the wheel, we see the drawing extension. This means the area occupied by entities in the model.
- Pan: By holding down the wheel and dragging the mouse, we slide the view, maintaining the same zoom factor.
