Whoah thanks Johannes ! I think the drawing is good enough for the model. I probably won't be going into a precision level that will require the usage of a scalable blueprint
Thanks everyone for the support but sadly I cought a cold and now I'm not even able to model anything properly. I will give it a try later today, hopefully I'll be able to create a basic outline of the mesh at least.
Thanks If poly count allows for it, I will add interior as well because I don't like empty spaces. Oh and for the poly count, I am always using the poly counter tool for precise measurement of each element. I am sure I will have plenty of polys to go about since the main shapes of the cab are done now. I will try to stay up longer into the night and try to do the trailer as well.
