Optimizing a UV Map

This is my first proper model using Blender and wondering if someone could advise me on optimizing my UV Map for texturing.

As you can see from the image below the selected faces from the 3D View is spread out over the UV Map image. My question is how can I get them to be together for easier texturing and then do the same with other parts of the train?

a tutorial on marking seams and unwrapping… it is designed for organic models, but the principles are the same…

Welcome to BA (Blender Artists)

Thanks for the link since I’ve been searching for a tutorial like that :slight_smile:

EDIT: After a better read of the tutorial I think I understand what I was doing different. I was using Unwrap (smart projections) which broke down each part of the mesh into small individual surfaces. With using Unwrap and seams I can keep all major parts of the mesh together and flat but knowing where to place the seams now is going to the hard part.
