Rotatability is needed for a Response Surface design
. A Matrix is rotatable if all the point have the same distance to the Center point
Rotatable is desired for the quadratic fitting of the model.

Examples of rotatabel Designs
Examples of a not rotatabel Design
As visible in the graphical image of a 3 factor Full Factorial Design
with 3 levels, the distance to the Center point variates.
