This paper introduces a semi-automatic, scalable pipeline for reconstructing trimmed NURBS CAD models into watertight spline representations, addressing the incompatibility of trimming with downstream engineering applications like CAE and CAM.
Citas
"In engineering design, one of the most daunting problems in the design-through-analysis workflow is to deal with trimmed NURBS (Non-Uniform Rational B-Splines), which often involve topological/geometric issues and lead to inevitable gaps and overlaps in the model."
"According to a study at Sandia National Laboratories in 2005 [3], the time spent to create analysis-suitable geometric models from CAD (Computer-Aided Design) models dominates the overall design-through-analysis process, which has become the de-facto bottleneck for the current software system to accommodate engineering designs with increasing scale and complexity [4]."
