Feature Selector

In order to create a new selection of features (aka Instance):

1. Open the Feature Diagram
2. Select the Instance View (see picture below)
3. Press the "plus" button

When a new instance has been created features can be select and deselected by:

1. Clicking on them
2. Clicking the "tick" button on the top bar (for selection) or clicking the "X" button (for deselection)

Finally it is possible to check that all the constraints (explicit constraints and sub-features cardinality) are satisfied by clicking the blue "i" button on the Instance View.

The Instance View also allows you to:

1. Remove Instances ("X" button)
2. Load and edit Instances ("folder" button)
