Although AutoCAD has a number of commands for creating special 3D objects, a lot can be achieved by changing the properties of basic 2D objects like polylines. Most 2D objects can be given a thickness using the thickness option in the Properties (DDCHPROP) command. Although objects with a thickness can be said to be extruded, this should not be confused with the EXTRUDE command which creates solid extrusions; giving an object thickness produces asurface extrusion. All objects can be given an elevation by moving them in the Z direction using the MOVE command. With a combination of the MOVE and Properties commands you can quickly create simple 3D drawings.

Using this tutorial you will learn how to give objects a thickness, how to move them vertically, how to view your 3D creations and how to use the 3DFACE and SHADE commands.
