 Hello,

 I am using v.net.path very succesful now (generating about 10 million
 routes without problem). The next step is creating a field in the database
 with the length of the path (i need the custom cost factor and the
 length).

 Using v.to.db on route sets of 300.000 features (x 45), is slower the the
 generation of the paths themselves. Since all information is available at
 the v.net.path  process, it is a good idea to add the length of the path
 in the database generated by v.net.path at record creation time. This
 would solve my problem in the best possible way...

 Is a update of v.net.path possible ???
