Tutorials For NoLimits Toolbag???

Hi Everbody,
I am currently learning 3ds max, and newb to the tunnel maker, object creator for NoLimits.I have found little to no instructions on how to use these tools...adding textures,colors,lighting and so on.I know I can make much more superior models and tunnels in 3ds max,but don't know if they need to be imported into another program to do this.Any help or pointing in the right direction would be greatly appreciated.The NoLimits tools seem to be very vague.Thank you very much for your time!
