Hi everyone, I got a problem with multipipe here.  
I created curves, lines, hoping to build multipipe with them.(fig1)  
However, the pipes are like being put together, but not connected.(fig2)  
When I baked the curves and lines in rhino, then the command multipipe could build connected pipes.(fig3)  
Who can explain this? Thanks very much.

I think you need to split all the curves input to MultiPipe at the intersection points.
