Autocad drawings for 3D printing

Hello, I have a plan and a section drawings of a module that i would like to have in an Autocad format to be able to use it for 3D printing. i will also provide a 3D drawing to insure correct drawing. The drawing i will you to produce should be more simple than the one i sent as i will only need the outlines to use for 3D printing. The module will be part of a bigger space when its joined with other identical modules, there will be junction pieces between the modules and sliding walls to inclose the space. i will also need you to draw the junction pieces and the walls so i can 3D print them separately add ad them to the modules later I will also send a section drawing as an example of two joined modules to explain what i mean and to show the section of the junctions and the walls and also will send a plan of the whole space made from the joined modules to show the plan of the junctions and how they work. Another drawing i would like to have which is the same module but i just show the structure so i can use it to 3D print a structural model. A 3D structural drawing is provided for you as a guide line. Draw the water tank separately as i will need to print it in another was as it will be a different material. further information can be discussed to also insure a proper drawing. The drawings are to scale on an A3 paper. the dimensions on the module is 8x2.5 m and the hight is 7 m Please make sure the drawings are clearly and correctly done for 3D printing so the result 3D printed pieces can be glued together and stand well as a structure. Thank you
