The blade modeling procedures with reverse-engineering software, i.e. Geomagic Studio, were presented in this paper. Thereby the 3D model of a Francis turbine blade was yielded, and the measurement results prove that the model tallies with actual blade successfully. Through utilizing 3D modeling software to analyze the model, some useful geometric or mechanical parameters can be obtained, such as the shape and curvature of the blade, moment of inertial and so on, and these parameters could be the basis for the optimization, study and maintenance of turbine blade.
