The MakeCharacter () macro uses the following variables:
Coordinate  is an array containing <x, y> spline coordinates plus a diameter
multiplier. The actual format is <x, y, multiplier>.
NPoints indicates the number of spline points in the Coordinate  array.
HeightFactor adjusts the scale of the character without changing the diameter.
BaseRadius is the default sphere_sweep diameter.
UseLastMinsAndMaxs is useful for making multiple parts of a character to be
It's fairly easy but a little tedious to make characters with this macro. What
worked for me was to make a bitmap image of the characters with a paint program
then mark locations along a path following the center of the character strokes.
The <x, y> coordinates of the marks can then be typed into Coordinate  array
entries and if necessary the diameter multipliers can be adjusted. With a little
practice one can achieve acceptable results. Don't forget that the first and
last locations aren't actually plotted since the macro uses the b_spline
