Thanks Chris - there is a ton of info on= the web about bezier curves and I am getting what the behind the scenes me= chanism is doing - but maybe my real question is if I create a spline via a= script I want to know how to calculate the in and out tangents to make a s= pline that mimics the auto bezier path. Is that even possible?
