If you want to create 2D drawings that represent 3D elements, such as cubes, you can create an isometric drawing. An isometric drawing is not a true 3D drawing, because you cannot view the drawing in perspective or from another angle. However, you can create a 3D effect by aligning the elements and objects in a drawing along three major axes.
SmartSketch supplies several tools to create these types of documents:
You can also use Customize on the Tools menu to place the isometric drawing commands on a toolbar. On the Toolbars tab of the Customize dialog box, click Draw in the Categories list, and then drag the various Isometric buttons to an existing toolbar or use them to create your own toolbar.
