Abstract:
Geometry reconstruction from 3D topology optimization results to Computer Aided Design (CAD) is challenging, especially for automation and non-beam-like geometry. While the optimized model has polygonal format, product development with CAD requires analytical surfaces in Boundary Representation (BRep). In this paper, we present two approaches for an automated interpretation of surface-skeletons for CAD-reconstruction. This includes the question, when to convert the skeleton’s polygonal to analytical surfaces and how to conceptually incorporate CAD features. One approach is based on decomposing the input in analytical, the other in polygonal surfaces. Both approaches work with specific skeleton-features and lead to a CAD-model with BRep-reconstruction. Exemplary results are presented.
