Engineering:- Take a compass and draw a circle of definite radius.
Architecture:- Draw a circle by general practice and give a shape of definite radius.
Vastu:- Circle is not a symbol of vastu.
As per my opinion Vastu is need base culture for every individual.For example vastu can be divided into groups based on caste,creed,culture,Location,situation,topography,environmental condition,etc.
