distancetotravel is not considering the path way direction.

[ FlexSim 23.1.2 ]

Hello everyone,

I need the distance between two control points going through the correct paths (not using the wrong direction). If I do the distance to travel from CP1 to CP2 is equal to CP2 to CP1 while the path is One-Way path. How can I fix this problem?

distancetotravel(Model.find("CP1"), Model.find("CP2")) --> 1864.03 (mm)
distancetotravel(Model.find("CP2"), Model.find("CP1")) --> 1864.03 (mm)

Thank you

Also using cpdistance function sometimes does not work.

The control point is not a traveller on the AGV network, so distancetotravel() will return the straightline distance.

If you use an actual 'AGV' (a task executer connected to the network) in the command, the returned distance will be along the network.

Do you have an example where cpdistance() does not work? Otherwise I'm afraid it's not really possible to troubleshoot the problem.

Hello @Jouky D ,

Distancetotravel needs as first parameter a traveler not an object. If you use cpdistance you don't have this problem. See the attached example: 23.1. CPDistance.fsm

I hope I have been helpful.

cpdistance() is the correct function for two control points, not distancetotravel. If you get unexpected results from this:

1) check your network integrity (visually)

2) refresh the path links (right click path):

3) check the routing accessibility (right clickCP) and then hover over other CPs on the network to see if it's reachable and the distance. You can use this to see at which point the route fails and detect broken networks.
