Whant to show you the project I'm working on.
This is the bigest project I have worked on. I have Intel i7 and 8 Gig Ram, and I can not practicaly work on it in this state as you can see on screen.
I've made 3 projects 1-Track, 2-Cargo and 3-Trailer. Also was made 2 sub projects for gun and Engine.
Than I merge it by import in one project.
