To zoom in or out of the canvas, select the Zoom tool button .

When you place your pointer in the client area, it changes to a magnifying glass. In zoom mode, you can click the left mouse button to zoom in or the right mouse button to zoom out. You can set the zooming percentage explicitly by selecting a value from the Zoom menu.

To zoom in on a selected area of the viewport, click and hold the left mouse button while in zoom mode. When you hold the mouse button and drag in zoom mode, Objective Views draws a rectangle to indicate the area into which you are zooming. Once you have the rectangle positioned in an area of the viewport, release the mouse button to select the area for zooming.

Objective Views also includes a zoom to fit feature, which sets the viewport magnification so that all components in the model are visible within the viewport. To use this feature, select the Zoom to Fit tool button.
