Through out my career as an Architectural Engineer and general CAD Draftsmen I've learned all the different programs associated with CAD or Computer Aided Design. Some of these software programs allow the process of 3D Modeling to be performed, and most of them are associated with Mechanical Engineering. With the technology within these programs it allows the user to apply materials and texture to be added, and rendering to be applied to the 3D models. With this sophisticated software users can create intricate Graphics with a lot of detail which allows the most detailed 3D models available to be created with computers.
Programs in particular like Autodesk's Inventor allows this process to be done with ease, and in a timely manner. Being in the business I have used this software to create 3D models which I use on my website along with several other projects which allows complete customization of anything it's inserted in. With this flexibility it allows me and others to create basically any 3D model the mind can imagine. For website owners this is great because they can actually get as specific as they want with the design. From the lighting, reflectivity, materials, and texture added to the models.
Having this power is an awesome tool for Webmasters, Graphic Designers, or any one in need for a 3D model that has to be customized. On my own personal website I can basically add any design that I want due to the fact I'm the one creating it. In most situations Graphic Designers have to use objects and images to alter in order to create something custom that no one else has. CAD Designers on the other hand use their imagination to create these images from the ground up which puts them in a better position to create images that are completely unique. Since I operate CAD and can operate Graphic Design software it allows me and my company to design images that no one else has access to which gives me the upper hand in any design situation.
To learn CAD most people have to go to school for a minimum of two years and sometimes probably more. The same goes for Graphic Designers, so if you can get educated in these two fields the possibilities of 3D design are endless. Graphic Designers and CAD Draftsmen can work together and create the most unique design imaginable.
