3D Engineering problem (Posted on 2006-08-02) Difficulty: 3 of 5
1. What 3D objects are represented by a pair of concentric circles in its plan (viewed from above) and a pair of concentric circles for its front elevation (vertical face)?

2. What would a #1 object be if it also has a side elevation that is concentric squares [with corner diagonals]?

(In reply to Laternative to Part 2 proposed solution by Kenny M)

This problem was a little like one I proposed sometime ago:
An 'Impossible' Solid
An excellent reconstruction of my model (which had been turned down as a brass paperweight) resides at the moment of this entry at:
devised by one of the respondents to my problem.

For my part in assisting Salil I saw the similarities between his challenge and my past entry. 

Neither of us being trained draughtsmen did not foreshadow issues that those with a more substantial engineering background would perceive, and for that matter protocols of the discipline.
