How should the lines in the tree look? You want to connect each point in the cloud with the one base point?

Yes, exactly connect each point in the cloud with one base point.

like the tree in the attachment.

Line

Single Point into A and multiple points into B

These were created in GH and displayed through GH. But all you need is what is inside the Highlighted Box.

Right Click on the Point Param and select Single Point for the Base and Then another Point Param and Select Multiple Points. rag the wires to the Line Components inputs and hey presto

The idea is not to connect a single point A to multiples point B directly, but to branches like a tree as in the previous attachment.

:) didn't see that. I thought this was to basic.

Here's a way using Daniel's recent Tree method in 3D.

It will need Giulio's Shortest Walk component which is highlighted above (Crucial), Andrew's Human Plug-in (Only for displaying line thicknesses) and Daniel Piker's Kangaroo Plug-in to Remove Duplicate Lines. All of which can be downloaded fromFood4Rhino

Here's another variation of the same theme allowing you to choose between cylindrical and rectangular in nature.

Thanks, this is the idea, but in my case I have already all the points, it is possible to do the same thing between my existing points.

Something along these lines:

Thanks for the solution, but in this solution,I draw all the lines each time, it is possible to remove all the similar curves. Cause after I want to make a pipe around those curves, and I don't want to calculate each curves many time.
Is it clear for every one?

Just explode the Resulting Polylines and use the Remove Duplicate Lines component again.

Thanks again, I will try this.
