Hello guys and gals,  
i have one question, like the pic shows, is that possible in Dynamo, merge three lines that in two different planes in one (poly-)line?  
Or do i need to write a python script to realize that, in this situation i still have no clue…  
Would be very thankful if get some advice…  
much thx…

</div>

or first merge two lines in one line and then join the merged line with the left line?  
Is that possible?
