Enhanced Reverse Engineering Using Genetic-Algorithms-Based Experimental Parallel Workflow for Optimum Design

Hybrid geometry / topology based mesh segmentation for reverse engineering

“…1 ): (1) tessellate the point cloud of the scanned model, (2) clean the raw triangular mesh (smoothing, filling, non-manifold repair, decimation, etc. ), (3) build the Boundary Representation (B-Rep) of the mesh, (4) segment the mesh, (5) fit the resulting partition with parametric surfaces (analytic and / or freeform surfaces), (6) build the B-Rep of the reconstructed CAD model, and (7) conduct the engineering analysis. RE applications include (but are not limited to) Finite Element Analysis (FEA) [2,3] , Structural Optimization [4,5] and Dimensional Analysis [6,7] .…”

“…Mesh segmentation / parameterization plays a crucial role in RE (steps [4][5] for the adequate geometric modeling of the workpiece.…”
