3D Polyline interfering with solids

    First, some background. What I am trying to do is use a genetic algorithm to determine the best path to route a pipe through an increasingly crowded space. Given a start and end point, I want to evaluate fitness based on number of collisions, number of nonstandard fittings, etc. . .
    What I am currently having difficulty with is a routine to test for interference between a 3D polyline, and various 3D Solids. Is there some pre existing bit of code that does this, or do I have to increment along the line and test to see if I am inside a solid or not?

    Thanks in advance for the help.

    I think you might be forced to use 3D Cylinders for your pipe instead of the polyline so you can easily test for interference. Of course you can make them as "thin" as you want.
