What is a Basic Feature ?

Basic features are very often the first entities you add to the active body to create your initial shape. They interact in unique ways with each other and with other functional features.

Basic features represent any type of material as well as empty spaces.

Inside and Outside

When you create basic features with any of the Functional Plastic Parts commands, inherent in the resulting features is the concept of inside and outside. This is the way that most people view objects, which affects how they would use an object. In the same way, design elements need to be either inside or outside of the product model. Thus, Functional Plastic Parts provides features with an inherent behavior of existing inside or outside of a material feature within the same body. For example, the behavior of a Rib is to exist inside of a shelled material feature, and the behavior of a Reinforcement is to exist outside of a material feature. Because of this inherent behavior, features can be made before or after creating the basic feature to which they will be applied. Thus, there are no history dependencies.

Basic features are defined by how they are manifested and how they interact with the inside or outside of another feature. Depending on the type, a basic feature does one or more of the following:

  • Adds material

  • Subtracts material

  • Increases spatial volume

  • Decreases spatial volume

  • Protects a spatial volume.

Therefore, when creating a basic feature that will intersect with another feature in the same body, you would select the volume type according to the results that you need.
