The problem of styling surfaces modeling is tackled. An approach based on section curves fairing is chosen. The concept of template curves is developed for approximating profiles with a monotone curvature variation. Constrained Bezier curves called typical curves are used for that. A curve growing process based on a G2 typical curve fitting method, is investigated. It consists first in determining a seed curve element then by a succession of extrapolating and fitting operations, to generate a curve segment with a given monotone curvature variation fitted locally to a data points set.
