Share 'Intersection Detection'

Hello All, "Intersection Detection" I am working on a definition where I need to test if a line is intersecting a surface. I need the out put to be TRUE or FALSE so that I might then use it to cull a list. It seems that all the intersection components provide geometry as the output. I have tried using the "Inclusion" components to no avail. Any ideas?  Thanks for the help!  cheers, Johnny
