I was looking on here:
and noticed that the wheels on many vehicles seem to follow the same structure.
These three ellipses seem to vary not only in size but also in degree.
I like the look of this method and wondered if its a standard method for wheels for feng zhu's students, as it seems lots of the students use it.
The other methods I see are usually a smaller ellipse off centre of the first ellipse, but seemingly the same degree giving the concave illusion.
Has anyone any input on any of this? Be it the actual method used, or any other info on whether it is fengs adopted technique or a standard technique for vehicle design?
Thanks very much.
