Envelope Definition

This dialog is used to edit an envelope’s topological definition.

An envelope’s definition consists of the Barehull as a minimum, but can additionally include a Main Deck and a list of Appendages.

The envelope’s geometry results from the interaction of this definition. The Main Deck being subtracted from the Barehull followed by the appendages being added or subtracted (depending if they are set as Positive or Negative respectively) in the order listed. The Envelope drop down list is used to select the envelope to be modified.
