If an element becomes surplus to the requirements of a model, you can delete it. Firstly, select the element and then:
- select Delete from either the main Edit menu or the icon menu, or
- with the keyboard, press <Del>.
The Editor will request confirmation, listing any references to the corresponding element (such as Resource Requirements or formulae) which will be discarded if you proceed. If multiple icons are selected for deletion, then the confirmation prompt will include an extra yes-to-all button. When an element is deleted, each corresponding icon is also removed from the respective views of the model.
