rhinoreverse 3 for Rhino 5 is an integrated plug-in for the Rhinoceros 3D NURBS modeler that helps in creating NURBS surfaces from mesh data.

---

Start by sketching curves on the mesh and then rhinoreverse 3 will automatically fit NURBS surfaces to the mesh. rhinoreverse 3 has the unique ability to represent large complex shapes with just a few NURBS surfaces by creating surfaces with 2, 3, 4 or more edges.

---

Furthermore, rhinoreverse 3 enhances Rhino's already powerful NURBS modeling capabilities by adding the ability to control continuity and tolerance between NURBS faces, healing NURBS models by adjusting faces and face boundaries, and filling holes in NURBS models within a given tolerance.

• Several import interfaces for mesh data (*.stl, *.wrl, *.vrml, *.af, *.nas, *.txt)
• Simple sketching of boundary curves on the given mesh data by using the mouse
• Flexible definition of the faces by 2 to 25 boundary curves (former: 4 curves define one face)
• Optional mode, to skin the point mesh "quick and dirty" with a low number of faces
• Flexible use of arbitrary T-joins for local refinements
• Use of several shortcuts to modify and enlarge the curve grid by mouse and keyboard
• Use of only one file (*.3dm) for saving all data
• Automatic calculation of topology by using graph algorithms
• Automatic approximation of the start faces to the point mesh
• Robustness against small holes and sharp edges in the mesh
• Automatic recalculation of face transitions to Rhino's tolerance settings
• Robustness against gaps in the point mesh
• Additional "healing"-function, to improve quality of already existing face models: automatic elimination of small gaps, steps and overlaps
• User-friendly RR-Patch to create complex patches
• RR-Relief transforms large relief surfaces given in STL format to NURBS face data for a homogenous distribution of control points. Steep surface areas are thus processed well and the handling of large meshes is simple and fast.
