3D assembly from 2D multiple components with different thickness.

I have a full vehicle with Body, Chassis, Suspension, Axle, Cabin, Floor, Roof, Glass, Windshield, Tyre, etc.. in actual manner as in complete assembly.

2D components are present. Now I want to create 3D in a single component for all the 2D components for my analysis. I don't have enough time to mesh all components in 3D & connect. I want to transform the 2D comp to 3D, the may be I can connect all the solids together into 1 component.

Please suggest an option. Is there any Batchmesh available or may be tcl script?

The Sample 3D model pic is shared for reference. I want the same thing.
