convert 2d polylinee to 3d polylinee

[Tremannaik]

good morning to all, I should convert 2d polylinee with object data associated in 3d polylinee without losing attributes.uso autocad map 3d 2011 and I do not find any lips able to make this conversion. . .
thanks to all

I doubt that the autocad lisp manages the map3d...
