That is how it works currently - if you have it enabled only edges of selected solids or surfaces will be get the hidden line display.

This new setting does not have any effect on "standalone curves" though, meaning curve objects like a drawn line or circle or something that are not edges of a solid or a surface.

It didn't really seem to make sense to apply this setting to selected standalone curves, because selected standalone curves already draw on top of everything so selected curves do not get drawn in the hidden-line style at all.

If the unselected hidden-line curves were getting in your way your best bet would be to just temporarily disable the entire hidden-line display, there is a shortcut for that in the View palette in the side pane, you don't have to go all the way into the Options dialog for that one.

Or just in general if stuff is getting in your way you can select it and hide it to get it out of the way.


But basically this new mode is to help manage edges not standalone curves - usually it's normal to have a lot more edges being displayed on screen than curves.
