This is the first release of the ShortestWalk plug-in.

This utility exposes a single command, ShortestWalk, which, given a network of curves, calculates the shortest path from one side to the other.

It is based on a topology calculator and the A* search algorithm.

I've tested this project, but it is the first release and it might contain still bugs. Please use it "as is", it does not come with warranties.

To install:

  • Save the rhp file in a folder of your choice (maybe not the desktop).
  • Right-click the file > Properties > make sure there is no "blocked" text
  • Drad-and-drop the file on a Rhino 5 window

Please let me know comments and ideas, and see the Grasshopper ShortestWalk component, too. The sourcecode for this command is published here.
