Reverse Engineering Surfacing: „reverse construction“ 2-Frame Setup / Frame 1

2-Frame Setup / Frame 2

· Creation of an CAD-data set of an already existing part · „reverse construction “ · From part to CAD

· Mathematical description of a component in 3D-space via reverse engineering of the STL data by creating mathematical defined objects and functions · curves (e.g. Splines) · Freeform surfaces (e.g. NURBS = Non-Uniform Rational B-Spline) · Standard geometries (Primitives) · Solids

· 3D-Scandaten (STL-mesh) as data base · Only full surface and detailed mesh data can describe the local curvature ratio of an surface precisely and lead to good quality of the CAD surfaces
