| + | Reverse Engineering is the process of transfroming 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. This precision is often required to manufacture the model back into a physical object. For instance, you cannot define precisely a radius or curvature on a mesh. Therefore by reverse engineering it back into a geometry that can be transformed with matehmatical precision, such as NURBS, the object can then be manipulated and edited to taste and sent back to any kind of prototyping machine. | ||

| + | Rhino is not a Reverse Engineeting program, since there are many aspects and tools needed to do reverse engineering. However, depending on your requirements, | ||

| + | Rhino 8 improves this process a step further than Rhino 7 by adding the ShrinkWrap command. | ||

| + | The set of tools in Rhino 8 that can help convert a scan into an editable part are: | ||
| + | * ShrinkWrap - to obtain a closed and clean mesh | ||
| + | * QuadRemesh - for remeshing and controling the topology | ||
| + | * ToSubD - to edit, manipulate and transform its shape | ||
| + | * ToNURBS - to convert it back and do further (precision) editing such as booleans, chamfers or fillets. | ||
| + | * MeshBooleans Improved - rewritten mesh boolean code that handles many corner cases and outputs a cleaner polygonal result, | ||
