I'am sorry. It's easier for me to give some lines of code rather than a good explaination in English even i know it's not 'educational'.
Sinc gave the way for the GetClosestPointTo() route, I only wanted to show there was no need to  draw two rays.
And Lee talk about the dot product way before I posted the codes.

Yes, but with a full function in front of me I got the message.

Because I assumed the nearest point would return the nearest vertex of a line.

The conclusion is justified that the initialization of the development of critical subsystem optimizes the probability of success to the development of the technical behavior over a given period.

Look at the code, it uses a Geometry.Line3d instance which has none vertex: it is unbounded.
The Geometry namespace contains plenty of classes (such as points, lines, segments, circular arcs, vectors, matrices, and so on) which aren't DBObject and are provided to solve geometry issues.
