Geometric Modeling Techniques

ME 459 Advanced Topics in Design and Manufacturing

1. Wire frame geometry

• User enters 3D vertices and joins the vertices to create a 3D object called a wire frame.
• The wire frame models lack the surface definition.

2. Surface model

• User enters the vertices and edges in an ordered manner. outlining or bounding one face at a time so that surfaces are defined.
• It can not relocation the volume of the part.

3. Solid model
