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]?

No, in that case the inner circle would be drawn with dotted lines.  Lines hidden from view, but visible if the object were made of clear glass, are drawn dotted.  At least, that's how I was taught...many years ago.
