How are the guide curves supposed to work?

I’m just testing out this feature and I’m not sure what the strategy for this is… as you can see, the magenta curves are lines pulled to the mesh, yet the orange result is quite bad:

What strategy should I use here? Should I do more, less?

Also, why do I need to pull the curves to the mesh? Seems counter-intuitive, because I have primitive shapes like lines and arcs which I’d think ought to help the remeshing more than the jagged results of the pulls…

Yeah same question. Ive played with it many occasions with mixed and mostly useless results. Anything too complicated just fails .
