This drawing done with TurboCAD v9.5 Professional got me
a bit of notoriety of sorts. It was selected and used on the
user's manual of the UK version of TurboCAD v10 Professional published
by
Avanquest software.
Avanquest is a republisher of IMSI's
TurboCAD in the United Kingdom. Below are additional views of
the model engine with one view showing a propeller mounted.
Drawing that propeller was not fun.
