Synopsis

duplicateCurve [-constructionHistory boolean] [-local boolean] [-name string] [-object boolean] [-range boolean]

duplicateCurve is undoable, queryable, and editable.

The duplicateCurve command takes a curve on a surface and and returns the 3D curve. The curve on a surface could be isoparam component, trimmed edge or curve on surface object.

Return value

string[] Object name and node name

In query mode, return type is based on queried flag.
