How to get points which only belong to the figure

Hello all, how can I get points that belong to the figure, that is, without points that do not lie outside its skeleton?

Hi @vadvirus,

You have not provided us enough information to help. Can you please try to restate you question? Also, sometimes providing a sample model is helpful.

Are you using the standalone openNURBS toolkit or openNURBS with the Rhino SDK?
