Introduction to Part Modeling

For conducting an FEA analysis, a part model is mandatory. In ANSYS Workbench, the next step after defining the material properties is to define the geometry to which the material properties will be applied. Like most of the other CAD modeling packages, the part models created in ANSYS Workbench are parametric and feature based. The parametric nature of an application is defined as its ability to use the standard properties or parameters (dimensions) in determining the shape and size of the geometry. You can also modify the shape and size of the model using these parameters. Feature is defined as the smallest building block of the model that can be modified individually.

Most of the 3D models created using ANSYS Workbench are a combination of sketched and placed features. The placed features are created without drawing a sketch, but the sketched features require a sketch to be drawn first. Generally, the base feature of any 3D model is a sketched feature and is created using a sketch. Therefore, while creating any design, you first need to draw the sketch for the base feature. Once you have drawn the sketch, you can convert it into the base feature and then add the other sketched and placed features to it to complete the 3D model.

In general terms, a sketch is defined as the basic contour for the feature. For example consider the spanner shown in Figure 3-1. It is created using a single sketch drawn on the XY plane, as shown in Figure 3-2.
