Chris,

You're welcomed! The history behind DrawBDL was that I got tired of 
drawing little sketches on paper to visualize what a model looked like, 
and wrote a little program that read the coordinates and turned it into 
an input file for a Unix-based sketching program at the Lab (TELLEGRAF). 
I then showed it to a programmer friend who said he'd try turning it 
into a PC program using Turbo Pascal. In 3 weeks time he had a working 
prototype, but being a real computer programmer Jim said that we were 
only half done.  So true that was!

One reason for the gaudy primary colors for the surfaces was that Jim 
was concerned about what graphics processors people had on their PCs and 
so stuck with 16-bit color. PCs were so limited in power then that when 
I went to DOE in the early 90's and demo'd DrawBDL on somebody's PC 
there, the drawing was so slow (blink ! another window! ) that I stopped 
the demo to avoid losing the audience.

Those were the days.
