WebReverse Engineering is the process of transforming a Mesh or Point Cloud, usually coming from the scan of a physical object, into a type of 3D geometry that can be editable to manufacturing standards. A mesh is a succession of flat polygons that define a shape in 3D space. However, due to its nature, meshes are hard to manipulate in a precise way. WebAttach Multiple Output Meshes. Produces a single mesh, even if the original NURBS object consists of separate surfaces.
