Is there a customer default or setting that turns curve names on in Sketcher? The Relationship Browser lists the curves by name, but that seems a bit useless if the curve names do not appear on the screen.
Preferences -> visualization -> names/borders, pick your desired option in the "show object names" listbox.
That's a step in the right direction and does help. I was looking more for something that would show the names while the sketcher was active but hide them when it was not.
