I'm just starting to learn how to write RhinoScripts with a view to
doing some simple toolpath creation for CNC machining.
I managed to create a little script that will produce a polyline that
looks a little like a square wave hovering above any objects that are
selected with a specified step over distance. The idea would then be
to project this onto the part to produce a rudimentary tool path.
The problem is that I would seem to need much more control over the
projection of the line than the command itself provides, I only want
the lines to be projected onto the top surface for example. I've
looked through the RhinoScript help file and have had a good look at
Rhino itself but am having trouble comming up with something, I sort of
want to do it point by point finding the the height of the first
surface directly below the point.
This makes me wonder if I should really be using the SDK rather than
scripts but I'm having a hard time working out if that will give me
much more power than I have or not.
