[maxmsp] 3d breakpoint function editor

hello
has anybody heard about a 3d breakpoint function editor?
or something similar to it?

id like to use it to draw faster and easier trajectories into  
ambimonitor and ambicontrol
objects.
Those 2 objects have lots of features for drawing trajectories, but I  
was just thinking that
a tool similar to the breakpoint function editor would be very  
precise and useful, as you can fix points exactly where you like and  
then draw and write the trajectory.

Any hint about that?

thanx in advance
