How to Use RhinoResurf for Rhino 6/7 to Create NURBS Surfaces from Meshes and Point Clouds
RhinoResurf for Rhino 6/7 is a powerful plug-in that allows you to create smooth and accurate NURBS surfaces from meshes and point clouds. NURBS (Non-Uniform Rational B-Splines) are mathematical representations of 3D geometry that can accurately describe any shape from a simple 2D line, circle, arc, or curve to the most complex 3D organic free-form surface or solid. NURBS are ideal for modeling complex shapes such as cars, boats, airplanes, jewelry, and sculptures.
In this article, we will show you how to use some of the main features of RhinoResurf for Rhino 6/7 to create NURBS surfaces from different types of meshes and point clouds. We will also explain how RhinoResurf can help you improve your reverse engineering workflow and save you time and effort.
What is RhinoResurf for Rhino 6/7?
RhinoResurf for Rhino 6/7 is a reverse engineering plug-in for RhinocerosÂ 4.0, 5.0, 6.0 and 7.0. This plug-in gives Rhino the ability to reconstruct the geometry represented by NURB surface of an object from a mesh or point cloud which describes it[^1^].
RhinoResurf for Rhino 6/7 has many features that make it easy and fast to create NURBS surfaces from meshes and point clouds, such as:
NURBS fitting with specified tolerance.
Controllable surface smoothness.
G1 continuity transition.
Powerful ability to fit large scale point cloud/mesh to a single face.
Fully automated nurbs surfaces generation.
Free-form nurbs surface modeling from polygon mesh (.obj mesh).
Fill hole by surface with numerical G1 continuity on the adjacent edges.
Match 2 surfaces to be tangent/curvature continuous on the common edge.
Unfold 3D mesh/surface into 2D mesh/surface.
Surface mapping from one mesh model to another.
Solid creation from mesh edge.
RhinoResurf for Rhino 6/7 is designed to be extremely user friendly and easy to understand. You load it manually at the first time and it automatically loads itself into the Rhino environment later. Once loaded it adds new commands to Rhino's existing commands and a new submenu called \"RhinoResurf\" to the Rhino menu containing these newly added commands[^1^].
How to Use RhinoResurf for Rhino 6/7?
To use RhinoResurf for Rhino 6/7, you need to have RhinocerosÂ 4.0, 5.0, 6.0 or 7.0 installed on your computer. You also need to download and install the plug-in from the official website[^2^] or from Food4Rhino[^3^]. You can try the plug-in for free for 15 days or buy a license for US$19.9 per month.
Once you have installed the plug-in, you can access its commands from the \"RhinoResurf\" submenu in the Rhino menu or by typing them in the command line. Here are some of the most common commands and how to use them:
This command allows you to drape a surface over a point cloud with specified tolerance. Draping a surface is similar to laying a piece of cloth over an object. The surface is deformed to take the shape of the object along the drape direction. The drape direction is calculated automatically[^1^].
To use this command, you need to select a point cloud in Rhino and then type RsPoints2Surf in the command line. You will be asked to enter a tolerance value, which is the maximum distance between the surface and the point cloud. The lower the tolerance, the more c481cea774
