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]?

Guess a cylinder on horizontal plane with a hole. From the top it is cut out into a circle such that the square shapes is not lost from lateral view. A square opening on the side with elevated sides to retain the shape in othe views. Too complex.

Am I near the solution Salil.
