I have been using blender and, vba, vb.net for more than a decade. I have been working in a family office , private banks, I now run my own business. I have building 3d printer and have an extended expereince in build API and I have work in data management. I can build any datasheet , automate everything even produce dynamic chart within excel although I would use any other programming language to do so and then I can 3d model the trucks and link the .stlfile to excel. I also did inventory management which give me a understanding of the management of the material and the way the trucks would be loaded.
We can discuss about the specs of the truck, materials adn the worksheet for inventory.
Regards,
Sylvain
