How to make continuous polyline?

[1ctoolfool]

when I use the "join" command in rhino then export as dxf, the entities are still individual curves and lines. I need to be able to export one continuous polyline, how to do this???

I tried "make periodic" but this changes the geometry

Please help, thanks

Don't have Rhino in front of me, but it may be in the .dxf export options?

yes, I found a toggle "explode polylines" was turned on in the export options, thanks
