CAD allows Inventors to design patents with precision by viewing the 3D CAD Models in different ways. These views allow them to fully understand the design.
In the CAD design field professionals use Views to simplify the drafting process by placing these stationary points in strategic positions that allow the maximum amount of dimensions and other necessary components to design the desired 3D Model. Basically there are only two types of views. The first is the perspective view and secondly the orthographic view.
A Perspective view on an object is observed from a fixed and stationary point, or point of view by means of converging rays of light that meet at the eye of the observer. These are the views that look 3D and give the design the illusion of depth. These views are very useful for presentation and understanding the orthographic views which are the blueprints for the 3D Model and designs.
Engineering drawings usually are composed of groups of orthographic views. Each orthographic view of the structure or object is seen by the observer when he looks at the object in some definite, chosen direction. Orthographic Views may be classified as three different types of views, the first view is the principal view, the second is the auxiliary view and the last is the oblique view.
The Principal Views are probably the most important views a CAD drafter will use and is how the necessary dimensions and information will be translated to design a 3D Model. These six principal views are the top, bottom, front, rear, right, and left side views. With these six views all the information for a 3D Design can usually be transmitted to the designer to create the 3D model, but in some situations the design calls for other perspective views.
A practice Engineers and Architects use throughout the design process is locating the origin of the design. This allows the designers to imagine a point within the design that will allow them to reflect the necessary dimensions in order to draw the design accurately. Once the 3d designer establishes this point the 3D model can begin to take shape. CAD software helps designers to locate the origin of many different designs especially in programs like Inventor and Pro-E.
Views within the CAD software available today allow designers to rotate there 3D models to locate specific areas and have a better understanding of where they are relative to the design. When you understand the principal views and know how to work off their dimensions the Design process becomes simplified. Once you can understand the information provided through both Perspective and Orthographic Views and then replicate the information to a design you are becoming a well rounded drafter.
