About Shellable Features

Shellable Feature is very often used to create the main shape of the part. It creates a hollow feature which you can open with Shell Properties.

Shellable Feature

Shellable Feature also adds material volume to the outside of another material volume that it intersects within the same body, thus extending the boundaries of the volume, as well as increasing the internal spatial volume of a shelled volume. The added volume inherits the shell properties (wall thickness) of the body.

Shellable features can have different basic shapes: Prism, Sweep, Revolve Thick Surface or an External Shape

Core Tab

The Core tab enables you to define a core body (offset) for a shellable feature. This sometimes becomes necessary if the geometrical complexity of the shellable feature is such that standard offsets fail.

If the part contains two or more shellable features, you need to choose between three methods:

  • Interconnected core: Automatically generates the core at solid functional set level through an offset of the union of all shellable features contained within the same solid functional set.
  • Isolated core: Automatically generates the core at feature level through an offset of only this shellable features geometry (i.e. the feature is independently shelled).
  • Select core: You can select any body to represent the core for the shellable feature.
Note: The faces of the features that have an isolated or a selected core cannot be later selected in Shell Properties as faces to remove or face with special thickness.
