Zooming, Panning and Rotating are basic operations of most graphically oriented programs. Here are the various options available in WMS and how they work.

  • Zooming In – To zoom in select the zoom tool and click on the part of the model to zoom in about, or drag a rectangle around the area you wish to fit in the graphics window.
  • Zooming Out – To zoom out select the zoom tool and hold down the SHIFT key (you will notice that the plus sign File:WMSimage340.png inside of the zoom tool changes to a minus sign File:WMSImage341.png as you move the cursor). Click on the point you wish to zoom out about.
  • Framing – Sometimes you just want to change the zoom so that everything just fits within the graphics window. You can do this at any time by selecting Display | Frame Image, or by selecting the Frame macro WMSIcon Frame.png.
  • Previous View – After zooming in/out it is sometimes useful to return the previous view. This can be done by selecting Display | View | Previous View, or by selecting the Previous View Macro WMSIcon Previous View.png.

Pan File:WMSIcon Pan.png

  • Mouse Click – by clicking on a location on the screen the entire display will be panned so that the point clicked on is in the center of the graphics window.
  • Mouse Drag – while clicking and holding the mouse cursor down you can drag the point clicked on to any other location in the graphics window.

Rotate WMSIcon Rotate.png

The Rotate tool provides a quick way to rotate the image on-screen about the x and z axes. Two rotation methods are available:

  • Single Update – Holding down the mouse button and dragging the cursor in the Graphics Window rotates the object in the direction specified in dynamically A horizontal movement rotates the image about the z axis. A vertical movement rotates the image about the x axis. The amount of rotation depends on the length the cursor moves while the mouse button is down.
  • Continuous Update – Holding down both the CTRL key and the mouse button while dragging the cursor in the Graphics Window creates an arrow vector indicating the direction and magnitude of rotation. This is useful because the image is not updated until after the mouse button is released.
