Which windows version are you using ? Cygwin or native ? If you can run 
d.mon x0, then this must be Cygwin.

How did you create this file ?

I don't know what point3d is, and am not a triangulation expert, but I 
don't see how the output of r.to.vect is useful for triangulation, 
unless you change resolution before r.to.vect...

Works in native wingrass.

Try running v.build on the file.
