So any line which doesn't intersect the shape, or which intersects it only once is removed entirely, and any line which intersect the shape in at least 2 places is trimmed after the second intersection point?

thanks for your help first.

i means that i wanna remove the line which is pass through the surface. 

the lines can intersect with the surface but they cannot pass through the surface.

I don't understand the difference between intersecting and pass through.
