Hello there I decided to sprit to new thread for easier looking. FRONT ENGINE SECTION ----------------------- I return back to designing and adding details to the engine. I drafted 3D model since last year. Now I am turning all parts to be a paper model. I have to add the paper thickness to each part. And design how to assemble them. For the engine I want to sprit to 3 sections. Front Engine , Back Engine and Boiler. I start from the front engine first. This section included with Engine Truck , Front Engine. Most of parts are ready to be unrolled.
