[Closed] how to get a sub-object position after it being deformed?

Hi all,

like the title said, I want to get a spline vertex position …I use the getKnotPoint command to get the position, but the thing is I used a skin modifier to deform the line, and I want to get the position After it has been moved by the modifier’s deformation, the former command gets me the position before the deformation which is not what I want…I wonder if there’s a way to do that.

i just want to constrain some point helpers to points on a spline…I though i’d put a script controller into the points position to get the vertices position to drive them…that’s the main reason for that, if anyone have an idea to help.

edit: nevermind…I did it with path constraint
