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]?

How about a sphere with two small circular dipression. One at the top & one in front. Its surface smoothly raised on the visible portion such that the discontinuity is not seen.
