I was exploring the ways in which we can implement the idea. My
proposed approach is as under:

Suppose we make an rcc and cut it with plane parallel to horizontal
axis. On seeing from top, we see a circle. Data like radius of rcc
(and so of circle) etc., is already stored in database file during
object creation. What we need to do is just retrieve such information
from database file and write there.

If rcc is inclined at some angle, then the intersection with cutting
plane will result in ellipse.

The question is how we can recognize such patterns (like circle or
ellipse in above example) obtained after cutting with plane and seeing
from top?
