create polyline from separate segments

[My_Key]

Hello
in google on 6 you can combine stripes of lines, or arches, so as to get a single polyline? I need to make a circular section curved handrail, so I wanted to use the follow me command on this line.
Thank you

partially bypassed the problem, in the sense that my problem was to select all these (which are numerous) line breaks to follow me, and I found that if I make "triple clicks" on a piece they are automatically selected all the other connected, and so just give it the command and it works. I saw that there is a free plugin called weld, to do what I was talking about in the first post. I'll try it tonight.
Thank you

weld is very comfortable and recommend to install it always. especially to use it with follow me (follow-me) when the path includes curved parts composed of several segments, because the surface that is created will already have the "soft" edges.
I have associated him with the alt+w keyboard command and use it often.
