Connect the selected block with the shortest line

[yxl030]

I looked up some existing programs, only find the shortest path and shortest loop.
How to achieve this effect?

This is the sort of thing done in road drainage is that what your doing ?

It's a simple electrical connection of multiple lights
 I thought it was complicated. Maybe I can do it by myself now, Thank you,BIGAL

Nice Pbe.

 

Ronjonp if you watch a electrician wiring up a house that is how they do it they just drag a cable, in a commercial project I agree with you were service locations are more controlled.

 

I am sure its something like shortest path and has been solved before.

Ronjonp,thanks 

As BIGAL said, that is a good drawing for drainage. But the wire joint should be at the wiring position of the lamp.

 

pBe ,that is very interesting, but I don't understand what it means. Is it an idea?

BIGAL, I found some shortest paths lisp, they are all between two points.

I've made it ,today . It's a little ugly, but can  be used.
