Uffe, As I have a client that would be happier to pay for the RW Net tool to do it than my time, I may well go this option and keep it up my sleeve for later. There has been one offer of a simple mapbasic routine that may work (I will try it tomorrow), although I suspect it may not handle the network that I have (19000 road segments). There has also been other commercial offers.
I also had a look at some algorithms and it scares me that 30 years ago, I could have understood them. You have a few list karma points in credit that it would be good to be able to repay. I'll have a tink about it tomorrow, but its too late now to think straight (its almost tomorrow now) r > Hi Robert, > > The easist and possibly also cheapest (your time taken into consideration) > may be to get a license for our RW Net Standard product.
