Hello,  
I would like to model in 3D the intersection of my two contours: “scinti” and “tep”. I’ve tried to do this with the “segment editor” module and the intersect option, but when I press apply, nothing happens. What should I do?  
thanks in advance

There is no need to create a new “intersection” segment. Intersection result will be stored in the current segment (that is selected at the segment list at the top).

Thank you for your answer. But how do I visualize in 3D this intersection?

I’ve made a short video about using the intersection tool. I hope this answers your questions. If you want the intersection to be in a new segment then you can first use the `Copy` mode of the `Logical operators` effect to copy one of the segments and do the intersection using that as current segment.
