CAD or CADD is the process where a Draftsmen manipulates

There are so many uses for CAD software nowadays. These complex programs can be used to design 3D Architecture, Mechanical parts for cars, boats, and even space craft. All inventions are designed with CAD software before a prototype is made. CAD files can insert data into CNC machines which allows molds, parts, injection molding, and other forms of prototypes to be created instantly. These machines are so precise they can machine a part down to a thousandth of an inch. CAD software has come a long way, and made the job of manufacturing better forever. No more slaving for hours over drafting tables with hand held tools that take forever. The software advances just over the last decade have been amazing, and I expect the job of design getting easier on the CAD Designers.
I've been in the CAD drafting, and 3D modeling field for almost two decades now. Throughout my learning I've come to find out that the most direct route to creating a design is the correct one. This basically means to try and create all of your main solid objects first. Once this is completed you want to start on the detail work. If you have several cut features for example, you can use tools within the CAD software that will allow you to duplicate the feature. Draw the feature once, and then use a command to either revolve the feature, copy the feature, or copy the feature and revolve it around a center axis. One tip a lot of designers don't know is that you can mirror a 3D object. This allows the CAD Designer to only draw half of the project before mirroring it on the center axis of your 3D drawing.
Once a CAD Designer fully understands and can operate the commands within the software he's half way there to becoming a professional. The next and most important skill to learn for a CAD Draftsmen is to review the design before beginning it. This period allows the designer to go about the most efficient way of producing the design. For example is a CAD Designer was designing a rim first he would get the dimensions for the side view, draw half of it, and revolve the rest around the center point of axis. Once this was completed, he would then begin to work on the internal components of the rim which would include cut outs, and various features for spokes, etc. Once the first cut-out was designed the CAD Designer could then use a command to make the same cut out, a given number of times around a single axis point of his or her choosing.
