Abstract
A stamping part design method including obtaining a first B-rep model having a 3D boundary curve formed by boundary-curve edges and obtaining a first and second value representing a g1-continuity and a g2-continuity extrapolation length requirement. The method includes determining a second B-Rep model comprising an extrapolation of the first B-Rep model and presenting at least a g2-continuity over a length of the extrapolation patches equal to the second value and then at least a g1-continuity over a length of the extrapolation patches equal to the first value. The determination of the second B-Rep model includes partitioning the boundary-curve edges into first groups of consecutive first boundary-curve edges, and second groups of consecutive second boundary-curve edges and applying a surface-extension operator to each first group and filling the gaps. This forms an improved solution of stamping part design.
