find Intersection and Point

Recommended Posts

Hello everyone


I'm looking for a way to find the intersection and the ring around the object.


After a few tries with Poly 3D and Nurbs I am now asking you.


Do you have a solution?



Thank you for your help

1. I need the two points above and below.
Where the hand-drawn lines and ring cross.


2.I would also like to get the red ring with Marionette.

I could possibly get the ring from a nurbs surface. To do this, however, I would have to be able to reduce the modification points of the nurbs surface in a targeted manner.


Is my explanation OK?
