I created PT lines in one sens but after I created the NTlegs cube created also automatically the backward of the lines why?
This is strange, as Cube does not modify the lines file when creating the NT-Legs. Could you please send some screenshots of what is happening to give a better interpretation? Thanks.
I found the explanation when you put the parameter of the line concerning the way with backward you must provide the parameter 'ONEWAY' to '0' instead of '1' to tell cube that this line must have backward but be sure that 0 is set in ONEWAY attribute (do it with compute) the backward line will have the same name with the symbol of '-' in the end telling that this line is the backward.
