Abstract: We describe an open source software package aimed at solving reverse engineering problems for CAD models defined in the polygonal form. We briefly discuss the main principles behind the new software, its architecture, and directions for further development. Examples of a turbine blade demonstrate the use of the software. In the first example, a turbine blade is reconstructed automatically from a structured point cloud. Another example is the interactive reconstruction of a turbine blade from an unstructured surface triangulation. In both cases, we use surface skinning strategy enhanced by a curve fairing operator. We illustrate by an example that the modified skinning operator does not minimize the total bending energy of the surface, but allows constructing a smooth patch where input inaccuracies are compensated. The reconstruction result is a parametric model of a turbine blade where the design variables are the coordinates of the poles of each profile curve. The presented software architecture can be used for partial or complete parameterization of the reconstructed CAD models aimed at their subsequent optimization.
Keywords: CAD, reverse engineering, CAD-model reconstruction, turbine blade skinning, fairing.
