The Magnifying Glass Effect
The following example illustrates the use of dynamic center. Details on a zoomed-in drawing in viewport 1 are viewed, and viewport 2 is used as a positional reference displaying the entire drawing.
The view in viewport 1 can be imagined as the view you would see if you were examining your drawing with a magnifying glass. To achieve this effect you must zoom in to the drawing displayed in viewport 1 until you can see the required level of detail.
• Viewport 1 — contains a magnified view showing the required level of detail.
• Viewport 2 — contains the entire drawing and is used as a positional reference for the magnifying glass.
