Description (last modified by martinl)

The manual states:

The syntax is as follows:

id start_point_category end_point_category
(Example: 1 1 2) 
or 

id start_point_x start_point_y end_point_x end_point_y

The CORRECT syntax is:

The syntax is as follows:

layer start_point_category end_point_category
(Example: 1 1 2) 
or 

layer start_point_x start_point_y end_point_x end_point_y

Are you sure? I don't see anything like that in the code. It must be an integer, but it is not really used there.

From first look it seems to me that the module supports two modes: coordinates and categories, see source:grass/trunk/vector/v.net.path/path.c#L141

OK, now I understand better your ticket. The 'id' is stored in created attribute table, source:grass/trunk/vector/v.net.path/path.c#L100. Why do you think that it should be a layer?

Replying to martinl:

ID is correct, it is the ID of the path to be created. Layers are defined with the arc_layer, node_layer, turn_layer, and turn_cat_layer options. Several paths can be created at once, e.g. with

1 1 2
2 2 3
3 3 4

using the syntax "id start_point_category end_point_category". The output will contain three different paths. You can then display a single path with d.vect where="id = 1" etc. Closing as invalid.
