More than ever, I see a need for a family of 3D modeling tools

What I would like to have is a family of 3D modeling tools, each optimized for doing a specific era and type. I would like to do 3d models of sailing ships, Dreadnought-era ships, and armoured fighting vehicles. I want to be able to drag and drop components. If I don't have a component, I want to be able to loft that component, and then reuse it in the future.
