How about the following problem as a first challenge?
Instead of solving one problem with everybody, each of us come up to 3 to 5 RhinoScript Methods we can use, and write one or more scripts.
Like we started learning AutoCAD only with
"L" "Pl" "O" "Co" "Tr"
Those 5 RhinoScript Methods will be our basic tools. Then everything else will follow!
You can find RhinoScripting Methods in Rhino
Rhino Help/ plug-ins/ RhinoScript plug-in
Then open RhinoScript Methods
A list of VBscript functions can be found here:
