Convert 2d sketch into a 3d sketch

I have a curved pole that is created using a sweep feature.  The path the sweep was made from is a 2d sketch.  I need to use this path in the assebly to create a path mate between a clamp and this path.  I can not create this feature using the 2d line sketch (path of sweep) as it needs to be a 3d sketch... Is there a way to convert the sketch into a 3d sketch or do i have to recreate this part?
