I have tried in GH to project the generic toolpath on some relatively
complex geometry and at first look if the toolpath is pretty dense, it takes
forever (not really good) and it's not even subdivide yet. I haven't look at
your GH file yet (but I will) and I'm not sure at all if doing projection a
la CNC Toolkit is the way to go because Rhino and GMax are pretty different
beast. Say we use those generic toolpath any way, ounce projected, we'll
have to figure out a mean to clean out the unwanted vertex as we have to do
with the kit, Hum!
I've been looking at the kit to see how he did it and I was happy to see the
method I used is pretty much equivalent to what I did, that is, first rotate
an axis by +- 90 degrees. Another thing I tried is to use a large number of
normal lines and GH seems to handle this quite easily. This suggest to me we
will need a more efficient mean to generate those normal lines then starting
from generic toolpath and projecting it on a part. Also, we will have to
figure out a mean to create a multi pass toolpath otherwise, all of this
work won't of much use in practice.
Before I go on, I'll a look at your work.
PS. As for posting this on GH forum, I would wait a little more, just like

I know it's just you & I at the moment Yves, but just in case someone else
wants to jump in . . .
Have to get some sleep, I'll feel better after.
We could drop some of this thread into the Grasshopper forum, what do you
think? Maybe we need to get some more of the ToolKit components completed
first? The key is to use the ToolKit as the outline for the methods &
components we need in the GH def. We could probably get some help there
animating the tool.
I'm thinking that this is a work in progress at this point & we can clean it
up & make it more clear & easy to use once we get it working better.
I'll have to test that g-code & cut air with my machine to see if it works.
