Envelopes

An envelope object is a collection of one base surface (barehull), a main deck and maybe appendages.

The envelope object can only be released as one entity; it is not possible to release only the envelope and not the parts it is built from, apart from appendages. Appendages can only be selected to be transferred or not, no individual selection of appendages for release is possible.

The above restriction has been adopted to maintain data integrity. By either releasing all appendages or skip them, it is possible to adjust the envelope object to reflect the difference on the Hull design side.
