Wire Frames
Wire Frames
Wireframes 8.1 A wireframe model is a skeletal description of a 3D object. There are no surfaces in a wireframe model; it consists only of points, lines, and curves that describe the edges of the object. With AutoCAD you can create wireframe models by positioning 2D (planar) objects anywhere in 3D space. AutoCAD also provides some 3D wireframe objects, such as 3D polylines (that can only have a CONTINUOUS linetype) and splines. Because each object that makes up a wireframe model must be independently drawn and positioned, this type of modeling can be the most time-consuming.

103
Surfaces
Surfaces Surfaces 8.2 Surface modeling is more sophisticated than wireframe modeling in that it defines not only the edges of a 3D object, but also its surfaces. The AutoCAD surface modeler defines faceted surfaces using a polygonal mesh. Because the faces of the mesh are planar, the mesh can only approximate curved surfaces. With Mechanical Desktop, you can create true curved surfaces. To differentiate these two types of surfaces, AutoCAD calls faceted surfaces, meshes.

Solids
Solids Solids 8.3 Solid modeling is the easiest type of 3D modeling to use. With the AutoCAD solid modeler, you can make 3D objects by creating basic 3D shapes: boxes, cones, cylinders, spheres, wedges, and tori (donuts). You can then combine these shapes to create more complex solids by joining or subtracting them or finding their intersecting (overlapping) volume. You can also create solids by sweeping a 2D object along a path or revolving it about an axis.
NOTE: Because each modeling type uses a different method for constructing 3D models and editing methods vary in their effect on the different model types, it is recommended that you not mix modeling methods.

3D Faces
3D Faces 3D Face 9.3 3DFACE creates a three- or four-sided surface anywhere in 3D space. You can specify different Z coordinates for each corner point of a 3D face. 3DFACE differs from SOLID, which creates a threeor four-sided surface that is parallel to the current UCS and can be extruded.
With 3DFACE, you control which edges of a 3D face are visible, allowing accurate modeling of objects with holes. Entering i or invisible before the first point of an edge makes the edge invisible. 1.
