This macro will move all selected objects in the drawing sheet to specified layer using SOLIDWORKS API.

Drawing layers
Drawing layers

There is no common ::Layer SOLIDWORKS API property to change the layer for any entity, rather this property is added to each interface which supports it (e.g. ISketchSegment::Layer property). This macro checks the type of the entity and calls corresponding SOLIDWORKS API property to change the layer.
