Urban path / itinerary

Hello, it's been a few day that i'm desperatly looking for a way to represent on a urban map some path.

I have differents starting point and i need to represent all the differents itinerary in a certain distance. For example i need to know all the area that is less than 400 meters from this point.

If i draw a circle, i will have the distance as the craw flies and I need to have the walkable distance.

I already have a single surface for all the roads.

PLEASE, if you have any idea, or reference fo someone else that have already done this kind of analyse, SHARE !

Hope i was clear enough,

Thanks a lot

Hi Tiffany,

You might want to experiment with the shortest walk: http://www.grasshopper3d.com/forum/topics/new-shortestwalk-for

and you can download it at: http://www.food4rhino.com/project/shortestwalkgh

Sorry can't help more without seeing the actual file.

Good luck

Regards,

Omar Helmy

Thank you, I've already tried this plugin but the problem is that in my file, the streets are nor represented by a single line but it it a void between the different built part.

Thank you

Can't really comment without seeing the actual drawing, but if you can have the paths represented by lines, the Shortest-path would definitely do the trick.
