Count the whole distance of different paths

Hi, I am working on the parking lot project and i need to count the whole distance of car travel from entrance to each parking space and exit the parking lot. Each of the paths should choose the shortest way from all paths from entrance to exit that I hightlight in blue. Because there are so many parking spaces, I am wondering whether there are altenative ways instead of to draw each routes and add them together to count the overall results. I have attached the pic and rhino model for reference.Thanks!!

First you need to define the curve network of all the possible paths similar to what you’ve drawn above in your diagram, but including access to all individual parking spots.
Then you can use the Shortest Walk plug-in to compute the shortest distances in the network.
