This zoom tool is the closest thing to a pan tool in DynaScape Design.
To use this tool, click on the icon once and then click on the screen. Move your mouse and you will see a line follow your cursor from the location you clicked on the screen. If your constraints are turned on you will be limited to their settings. Click on the screen again in a different location from the first and your drawing will be centered on the last location clicked. If you are in the middle of a drawing or editing function, you will need to click on the icon again to activate it again.
