Use Zoom Window to quickly zoom in to any specific area of the model. To use Zoom Window:
Select the Zoom Window option.
Use the left mouse button to select one corner of the area you wish to zoom in on. When you move the mouse, you will notice a rectangular window opening up.
Use the left mouse button to select the opposite corner of the area to be zoomed.
The view will then be updated, scaling the area that you have just selected to fit in the view. The view will always be updated to show the ENTIRE window you have selected, even if it is not the same "shape" as the view.
The corners of the zoom window can be entered as x,y coordinate pairs in the prompt line at the bottom right of the screen. This is useful if you wish to zoom into exactly the same region on different views, or on different models, for example.
If you are not satisfied with the result of using Zoom Window, you can always try to improve the view by using Zoom In , Zoom Out , Zoom Mouse , Pan , or using Zoom Window again. If all else fails, select Zoom All and start over!
To cancel the Zoom Window option (before you have entered the second window corner) use the Escape key, or right-click and select Cancel.
Zoom Window is available in:
The Zoom sub-menu of the View menu
The default right-click menu
Another shortcut to Zoom Window, is to CLICK AND HOLD the RIGHT mouse button, and then drag to form a window. When you release the right mouse button, the view will be zoomed to the window.
