  
Cubic elements can be skewed, rotated, translated, replicated,
repeated along straight or curved paths, and are the primary tool
for most projects.
Here are some cubics defined in a text file using Notepad:
start x y z x y z
point minimum values maximum values rotation color

You can build a library of objects, then
rotate and translate them for precise placement:
 
Cubic elements can be repeated along an axis, then rotated
and translated into position:
x y z x y z spacing endcube rotation color

Standard points, lines and planes are also useful:
