Reference for Zoom Tool

Use the Zoom tool to change the zoom magnification of a model. The following mouse click and key combinations are available to control how the Zoom tool behaves:

  • Click. If you click the Zoom tool on a wheel, the current view is zoomed in by a factor of 25 percent. If you are using the Full Navigation wheel, incremental zoom must be enabled in the Options Editor.

  • SHIFT+click. If you hold down the SHIFT key before you click the Zoom tool on a wheel, the current view is zoomed out by a factor of 25 percent. Zooming is performed from the location of the cursor, and not the current pivot point.

  • CTRL+click. If you hold down the CTRL key before you click the Zoom tool on a wheel, the current view is zoomed in by a factor of 25 percent. Zooming is performed from the location of the cursor, and not the current pivot point.

  • Click and drag. If you click the Zoom tool and hold down the button on your pointing device, you can adjust the magnification of the model by dragging up and down.

  • CTRL+click and drag. When using the Full Navigation wheels or the mini View Object wheel, you can control the target point used by the Zoom tool. By holding down the CTRL key, the Zoom tool uses the location of the previous pivot point defined by the Zoom, Orbit, or Center tool.

  • SHIFT+click and drag. When using the Full Navigation wheels or the mini View Object wheel, you can zoom in to an area of the model by dragging a rectangular window around the area you want to fit in the window. Hold down the SHIFT key and then click and drag a window around the area in which you want to zoom.

    Note: If you hold down the CTRL key along with the SHIFT key, you can zoom in to an area of a model using a center-based window instead of one defined by opposite corners.

  • Mouse wheel. When a wheel is displayed, scroll the mouse wheel up or down to zoom the view of the model in or out.

Note: When you use the Zoom tool from the Full Navigation wheel or the View Object wheel, the point in the view where you click to zoom becomes the Center point for future Orbit operations until you either use the Zoom tool again or use the Center tool. If you press CTRL before you click the Zoom wedge, the Center point does not change.
