Autodesk Inventor provides many powerful modeling and design-tools, and there are many different approaches to accomplishing modeling tasks. Most engineers and designers can relate to the experience of making rough sketches on restaurant napkins to convey conceptual design ideas. This method also conforms to the design process that helps the designer with conceptual design along with the capability to capture the design intent. Computer input and output devices we use today are largely twodimensional in nature, which makes this modeling technique quite practical. Many designs are in fact the same shape in one direction. The approach of creating two-dimensional sketches of the three-dimensional features is an effective way to construct solid models. Create the desired drawing views to document the design. Perform analyses on the computer model and refine the design as needed. Add additional parametric features by identifying feature relations and complete the design. Extrude, revolve, or sweep the parametric two-dimensional sketch to create the base solid feature of the design. Apply/modify constraints and dimensions to the two-dimensional sketch. Create a rough two-dimensional sketch of the basic shape of the base feature of the design. In Autodesk Inventor, the parametric part modeling process involves the following steps: 1. The design variables, described in the sketches and described as parametric relations, can then be used to quickly modify/update the design. Parametric modeling is accomplished by identifying and creating the key features of the design with the aid of computer software. The word parametric means the geometric definitions of the design, such as dimensions, can be varied at any time in the design process. IntroductionThe feature-based parametric modeling technique enables the designer to incorporate the original design intent into the construction of the model.
