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 re: a thought on part 1 by Ken Haley)

ok, thank you for the clarification :-D.  What kind of drawing or design would this be called?  I am having dificulty finding information about this kind of design on google
