    AutoCAD 2007 Tutorial – Second Level : 3D Modeling. Modeling tutorial objectives : Create 3D Surface Models, Understand and Apply the Different Surface Modeling Techniques, Understand the Use of the 2D SOLID Command, Using the Predefined Surface Models, Understand the Use of 3D FACE Command, Use the Hidden Edge Option. As illustrated in the previous chapters, there are no surfaces in a wireframe model; it consists only of points, lines, and curves that describe the edges of the object. Surface modeling was developed to provide the surface information that is missing in wireframe modeling.
    Essentially, defining the skin of a design creates a surface model. Although it is possible to create a surface model without using a wireframe model, in most cases it is much easier to create a surface model on top of a wireframe model. In surface modeling, a wireframe model can be used to provide information about the edges and corners so that the desired faces can be easily positioned and placed.
