PANEL DRAWINGS

XLTA_HOME

Below are links to drawings for each of the 13 panels. (The panels are numbered from 1 to 13 going from bottom to top.) Each set of panels is sewn together to make a "gore" that runs the entire height of the envelope.

The shapes in the drawings are not to scale and have been simplified somewhat. In particular, the panels are typically not exactly the trapzoid shape shown. Rather, most panels have their top and bottem edges "trimmed" slightly. See here and here for more details. This trimming gives the envelope a much smoother shape.
