Issue with the Connect Line Tool

[Corey]

It will remove faces with "zero size", isolated vertices, smallest edges and maybe something else. It has a RMB option which you can set some parameters.

But what about the process? Did you finally was able to produce the right shape?

Yes I successfully got up to the next part of the tutorial and am now attempting to make my propeller match the tutorial as close as possible. Which can be difficult considering how there are only "Play Around" measurements. I will certainly come back here if I run into anything beyond explainable.
