Oh! Now I understand LinePick... well, sort of. But what does the radius paramater mean? Is there a default radius if you don't use it?
Am I right in that LinePick is like drawing a line through 3D space, and returning the first entity that that line touches? What is meant by "first" entity? If there are two, which will be "first"? When would you use it?
