Thanks Michael. However the issue shown in the video with regards to the shelling/offsetting gaps being introduced were created with "sweep" not "network". The file you attached (which I assume was also created with "sweep") produces the same issue when "shelled" with a large amount (such as a 10 cm shell "normal"). The final shape I am trying to recreate is the upper bridge superstructure of the studio scale filming miniature of the U.S.S. Enterprise from Star Trek: The Motion Picture.
