We present the composition of G/sup 2/ curves by joining circular arcs and/or straight line segments with cubic Bezier and Pythagorean hodograph quintic spiral transitions. Recent work demonstrates some applications in geometric modelling and a constrained G/sup 2/ continuous spiral transition curve that falls within a closed boundary.
