rxDuplicator tool (v1.14) - allows you to create and place several copies of the selected elements along a path. A path is an open or closed curve or its part. As a path, you can use any 2D drawing elements, grouped segments of 2D elements, including splines and elliptic arcs, and any polygonal elements, like slabs, hatches etc.
