Wrapping DLA shape with Shortest Walk, returns error

Hi,

From the title, I have the shortest walk component turning red, saying that the start and end points are the same.

Furthermore, I am trying to wrap this shape curves, and am wondering if there is a better way to achieve. Any help would be greatly appreciated.

Here it is with a random point option.

Incidentally, I am more interested in creating networks on surfaces with multiple walker paths. I can only achieve this now with two separate walker components. Using two components yields the problems of having two separate networks. (Which is alright - see image)

However, what I really want to achieve is to have multiple points and have the network create density and flow toward the separate points. Say, it starts with one moves towards a middle point, and then flows towards a third. Unfortunately, this is not what I am achieving below. Any help would be greatly appreciated. Thank you.

There is an error, I tried to understand it but I didn't find. I suppress 0 length lines with no results. But it works !!

Thank you Laurent,

Interesting method to add variable thickness to the lines as well. I agree, I'm not sure why its in the red, but seems to work. I appreciate your solution.

Erik
