For some exercises of this chapter you'll need previously made Models.
You can find these in Teamcenter via:

To reflect certain characteristics of a product within a CAD-system, features are used.
A feature is a previously defined form element, that resembles a technical funtion, like a groove.
In a Feature, various basic elements are compiled and referenced to eachother, to quickly create a complex technical function. For example, a counterbored hole consists of two circular elements, that are extruded to a certain depth. Both cylinders are concentric to eachother and are using the Boolean operation Substract
. In addition to that a drillbit is created via a rotated sketch.
These basic functions are compiled in the feature Counterbored Hole, so you only have to define diameters, depths and position to create this complex geometry.
Features are generally separated in two categories:
- separated according to boolean operation
- substracting features
- additive features
- separated according to field of application:
- for milled parts
- for formed parts
- for rolled parts
- etc.
According to this differentiation features are grouped in libraries. In addition, you can create custom features.
