In this example of 2D CAD design<\/a>, Chetan was commissioned to provide a drawing of some old chamfering cam gear machinery because no other reference to this old technology could be found. Chetan used reverse engineering, whereby, some existing item is taken apart and studied so that its components can be graphically represented. Perhaps, the machinery still works well, but its parts are showing wear and replacements are not available. With an education in mechanical engineering, someone like Chetan can get new parts milled from his drawings.<\/p>\n Apart from situations like reverse engineering<\/a>, most people with ideas want to skip the 2D stage and go directly to 3D Rendering. This approach gives instant life to an idea, but it again requires skilled individuals, with engineering backgrounds, to produce accurate, workable concepts. From Cad Crowd\u2019s database of almost 20 thousand CAD freelancers, the chances are excellent there\u2019s a perfect designer there for every project.<\/p>\n London-based Rufus Edmondson has been registered with Cad Crowd a number of years. He graduated from an architecture program. Not surprisingly, he specializes in 2D and 3D drawings for architecture and jewelry applications. Look at the detail of this 2D concept for a counterweight tensile canopy<\/a>. Rufus opens eyes with his detailed 3D Rendering of a piece of bangle jewelry that divulges every score mark and etching. You get the feeling of being at this Tokyo casino and theater<\/a> he designed for a client using architectural modeling and specialized software to create a 3D visualization.<\/p>\n In many applications, such as real estate, 3D Animation provides even more reality to a lifelike scene like a walking tour of a house or apartment that isn\u2019t built yet, or a medical procedure with a virtual patient.<\/p>\n People with concepts that need to convince funding institutions or investors of their idea’s viability need excellent presentations. Including a 3D Rendering in your portfolio certainly gives any idea an edge that explains it succinctly. Here\u2019s an idea that could be hard to explain or envisage without a precise drawing.<\/p>\n Like you lock up your house and your car, this concept, presented by a Malaysian designer, let\u2019s you secure your workplace when you\u2019re absent. Imran Othman<\/a> says he thrives on innovation and defines himself as a \u201ccertified human-centered design practitioner.\u201d<\/p>\n Often with designs like Imran\u2019s, particularly for commercial items with working parts, it\u2019s necessary to advance the concept by making a prototype. By having a working model, any shortcomings can be identified and remedied before going into production. Cad Crowd\u2019s resource of prototype designers and modelers can equip you with an exact representation of a product with 3D Printing, even in the color of your choice. All you have to do is test trial with family, friends or fellow workers. Perhaps if you had known the client of designer Gloinnt, you would have been allowed to try out this tricycle prototype design<\/a>:<\/p>\n![\"CAM](\"https:\/\/cdn.cadcrowd.com\/blog\/uploads\/2018\/10\/CAM-gear-rounding-machine.png\")
