Hi Moka - you mean edge curves of a surface or solid?

Select the edge (to select all edges, first select one and then use Select / Select All) and use Edit / Copy and Edit / Paste to duplicate them.

Also if you want to grab a quick copy of a single one, select it and use ctrl+drag to drag off a copy.
