[Maya-Python] breaking curve tangent

[e***@gmail.com]

Hi there,

i was wondering if anyone knew a way to break a tangent at a particular edit point. I have created an ep curve and i want some of the curves that are created between the edit points to be linear rather than cubic.

is there a python command for this ?

thanks,
Sam

Hi Sam,

That's not so much about Python as it is about how curves are defined in
Maya. Curves have a very specific "Degree" (cubic) which means that
generally you need n+1 points to define a given span. For a cubic curve,
that means 4 points. In order to make a sharp corner, you would need to
place 4 points on top of each other (you can snap them with the 'V' key).

In script, it would be the same type of thing. In theory (I haven't tried
it), you could set up a tool that would read in your curve, read a selected
point, and then recreate the curve with 4 points at the point you selected
instead of the single point, but it would take some noodling. NURBS are
not quite as friendly in that way as Bezier Curves are.
