AutoCAD 3D Modeling is the creation, manipulation and storage of geometric objects to represent objects that are all around us, or virtual objects using advanced software. The process begins with the use of specialized 3d software. The 3D artist develops a mathematical, wireframe representation of the object using specialized software. The final product is called a 3D model and the process is called 3D modeling.
It is very common that people visualize mentally in 3D. When we are thinking about any particular object nobody thinks of it as three projection views. It is visualized as a single pictorial object. AutoCAD 3D modeling works the same way, with the designer creating 3D model on screen as if it was in his mind. Having manipulated and added entities to complete the AutoCAD 3D model, he can adjust the model to look at it in front elevations.
These elevations are the projection of 2D drawings - exactly the same drawings that were created using traditional 2D methods. The pieces can be viewed individually or as a module, so that we can get detail and assembly drawings from the common model, without having to develop it in separately individual parts.
We are all familiar with the Aristotelian argument about the relation of poetry to action. Action, or praxis, is the world of events; and history, in the broadest sense, may be called a verbal imitation of action, or events put in the forms of words. The historian imitates action directly; he makes specific statements about what happened, and is judged by the truth of what he says. What really happened is the external model of his pattern of words, and he is judged by the adequacy with which his words reproduce that model. The poet, in dramas and epics at least, also imitates actions in words, like the historian. But the poet makes no specific statements of fact, and hence is not judged by the truth or falsehood of what he says. The poet has no external model for his imitation, and is judged by the integrity or consistency of his verbal structure. The reason is that he imitates the universal, not the particular; he is concerned not with what happened but with what happens.
—Northrop Frye (1912–1991)
Once the 3d model is done, the 3D artist may begin the process of 3D rendering for visual representation in 2D or use the 3d model for an animation. Also, the 3D model can be used for other applications including computer simulation of physical phenomena. The 3d model can also be physically created using 3D printing via rapid prototyping techniques. When 3d printing is used, the 3d object is created connecting layers of cross sections of material.
Outsourcing you 3D AutoCAD modeling and 3D building models requirements provide many benefits including better design quality, expert help, competitive edge, lower cost, reliability and project efficiency. That is why CAD design outsourcing is adopted as the most profitable option in construction industry today.
