Did you know you can zoom in on any area of a model just by creating a box in the graphics window? This feature is very user friendly and provides quick access for zoom-in capability.

Box zoom is a very useful feature, especially when you are working with large or complicated models. The feature is available in CFD-GEOM, CFD-VisCART and CFD-ACE-GUI.

• Press and hold the Shift Key
• Press the middle mouse button and drag it to draw a box/lasso in graphics window to zoom in that area

Let’s say you want to zoom in on the airfoil trailing edge, as shown in figure 1 below. Press and hold the shift key, press the middle mouse button and drag it to draw a box. On releasing the middle mouse button, you will be zoomed in on the box, as shown in figure 2 below.

Note:
CFD-VIEW has a lasso zoom feature that is activated by selecting the 'View -> Lasso Zoom' menu option as shown in figure 3 below. The lasso area is then specified using the left mouse button.
