Making one single curve without breaking

Hello ,

Could you please help me about my problem ?

I insert a dxf drawing to the rhino.It came like block.I explode it.But I have to make all lines and curves , one single line or one single curve.

Because I will send this drawing to the 3d printer but it has to be just one ine or one curve.

How can I solve ?

Normally, if the segments are all lined up correctly, the command Join should do what you want…

Hi -
Apart from what Mitch said, unless those curves make up the slices, it doesn’t make much sense to send curves to a 3D printer. It’s probably best if you upload (part of) your 3dm file.
