need to design a sphere with 7 feet, 8.5 feet and 10 feet diameter. It should be designed in a way that each part to assemble should be of same size. Parts should be detachable. A person should be able to detach 1 part and enter it and person outside should be able to attach it back. If the sphere rolls then part should not detach. Air should pass in the sphere. Design should be in a way easy to produce. It should be very attractive for viewers. Advice me the material to be used.
person should be able to stand inside
Don't Wants:
I don't want any design either its not possible to make or very costly.
  1. CAD
Additional Information
The design of Sphere as well as parts should be in 3D. Exact measurements needed

This is fully Enclosed. Sphere. Like a soccer ball. Definitely, parts sizes will be different for 3 different spheres. But, their shapes would be same. Minimum number of part types. There should be 4 entry exit points. Top, Bottom, Right and Left. I think, the part shape of these points should be different than all others. I believe so. But, designs and ideas should come from designers. The ball would be rolling with weight in it. So, Keep in mind attachments of parts during assembly. That these parts don't detach while the ball is rolling. Also, keep in point 4 parts ( Entry and Exit points). These parts will be regularly attached and detached for entry and exit. So, they should be attached in a very secure manner. At the same time, the ball surface should be smooth from inside and outside.

Sprocket Assembly
I have a design that in appearance is similar to a sprocket and hollow shaft. There is a need for a 3D model that can be used for rapid prototyping/molding. The final design should be in Autocad 3D and as shown in the Sketch referred to as Fig. 9. Attached are two 2D Autocad drawings of the “Support” and a “Tube”. Also attached are two scanned images Fig 1, Fig 2 and Fig 3 of the changes with instructions. Originally the Tube and Support were designed as two separate parts to be assembled together, but the new design requires that they are to be made as one “Assembly” as shown in Fig. 3. The following changes have to be made to the Tube FIG 1: The Tube has to be reduced to 2 inch long. The top portion of the tube has to be deleted. The Tube Outer Diameter has to be increased to 7/8 inch and the wall is 1/8 inch. The Tube is now placed on the support aligning the Slit This makes the Tube and Support one piece called the “Assembly” For additional information see Fig 2 and Fig 3. The 3D drawing will be used for Rapid Prototyping. 1. I would need a 3D drawing in Autocad, and possibly also in one of the following formats IGES (.igs), and/or SolidWorks (.sldprt) and/or Stl that is generally used for Rapid Prototyping. 2. I will also need the 2D drawing of the Assembly in Autocad. This design is not to be distributed or used by anyone else without prior permission from me. All items sent to you must be destroyed or returned to me. Thank you, Frank
