I don't know what are those two thick lines. I query them and they are Not etches. Yet the Pin they intersected with and island plane have the same Net, VDD.

I try to find out what are those two thick lines,

You mean the pink ones? They are the real space the component will occupy once welded. If you have ever seen a SMD PCB you will see resistors and capacitors with tin lead at both ends covering the pad. That's because tin lead needs a surface to be spreaded once molten, otherwise the component wouldn't endure.
 

The two lines that form a V are relief copper connecting the pad to the power plane.... You have your pad relief set to 45 degrees.

Two points components are soldered...
Very little tin/lead solder is used these days, RE. RoHS 2006.

how come when I probe them they are Not listed as Clines or Cline Seg?

I think, names are a bit arbitrary in this regard, but actually the thermal relief isn't part of a routed connection. It's an autogenerated copper feature for a pad placed on a copper pour.
