Attached GH code uses internalized geometry so the Rhino file isn't needed.

thanks for your help

is there any other method to this...
the list item component will be much more if there are many lines here.

The list of intersection points will vary depending on how many times it intersects the surface; how you handle those points is up to you.  In this case, the "curve" was a straight line so I just took a short cut by creating new lines between the points, but that would be handled differently if the curve was really curved.  More like this - but note that you may have to combine two or more of these segments to get the result you want?

thanks for your help...
this combination of component is very near to what i want.

the follow picture is presenting my meaning. 

if there are 5 or 1000 lines pass through the surface, i think "list item "component is very trouble to previewed off...

so is there any better method to instead of using "list item" component?

What more can I say?

If each of the 1000 lines has the same number of intersections, 'List Item' works great - if not, then...?  Well, then what?  You have a bunch of segments.  I've answered your question two different ways - the student must make some effort!  :)
