Blade Generation software.

Felipe Figueroa

I work in the generation of blades (and the rotor of centrifugal pumps) with a rapid prototype machine that use stl archives. The idea is digitalice the important points with an arm. Them, with a cad software, generate the points for export to a program that generate the blade geometry (as a solid o surface). Finally export the geometry in stl format. I don´t now what program help me. I need an alternative to bladegen. Thanks.
