The document discusses 2D and 3D CAD software capabilities for drafting and design. It describes how 2D CAD is useful for diagrams and schematics while 3D CAD allows for visualizing objects and assemblies. 3D parametric CAD can create parts, assemblies, and drawings, with changes automatically updating linked components. Part modeling involves functions for machined, molded, sheet metal, and welded parts created through sketches. Assemblies add relationships between parts using mates. The document promotes the author, Norman F. Simms, as an electrical and mechanical designer who can help others understand and apply CAD technologies to new designs.

4. 3D Parametric CAD has 3 Basic Functions - To Create,
Parts, Assemblies, and Drawings / Documentation
Note: Parametric means that If the part changes, the assembly and drawing will reflect the
changes also

This presenation only shows a small part of the many capabilities of CAD
technology. All the models and drawing were prepared by myself with various
CAD programs.
If you are someone who is trying to understand CAD, I hope this was a help.
If you are someone who need someone to help them create new design and
documentation, I hope you will use the number below and give me a call.
Thank You for Your Time.
