No such object as wire segment exist according to my knowledge. Only joints. Segment is only visual representation of connections between joints. Joint may be either bend, junction, end or loose end. From the joint wire may go to up, down, left and right (any combination for junctions, two directions for bends and one for ends). If selected segment of the wire is a connection of given joint, its 4th bit (0x8) is set to 1. Only in this case bits 5th and 6th (0x10 and 0x20) have sense. 0 for 0x10 means that left joint side is selected (if present) and 1 means that right joint side is selected. Similarly for 0x20 bit for up and down respectively. Note that bits 0x10 and 0x20 have not much sense for junctions - where segments may be selected in up to 4 directions. Two bits are simply too less to describe such situation. Two figure out what is the situation with selection for junction you have to follow the wire further to the next bend and read it out from the bend. What if you have few 4-directional junctions in row? I don't know. But gb119, what do you exactly need it for? Is Selected property and then first element of Terms[] property not enough to get a source of selected wire?

This is not required as: (from documentation)But I guess that gb119 would be more interested in this:
