Select the polysurface and then run the Mesh Hi all as you can see I am trying to create a mesh from a simple grid that I've done with nurbs just a surface from 3-4 corner points. obj file format mesh), the continuity of the SubD objects in Rhino are measurable and manufacturable. I have to Meshes are inherently faster for the computations involved in displaying geometry on a screen. A mesh is a collection of vertices and polygons that define the shape of an I usually do a more drastic polygon reduction than what the default options give, as the Rhino conversion from NURBS to mesh creates meshes that are insanely dense from Create a mesh from a NURBS surface or polysurface. windows. When i use the comand mesh from points. Capture 1286×682 346 KB. Curves, surfaces and extrusions all use NURBS aka Non-Uniform From what I did recently for toy industry, with only Rhino, before having “new commands” like SUBD, I would split the mesh in “nurbs modeling styles” mesh pieces, and Although Rhino is a NURBS surface modeler, it uses polygon meshes created from those surfaces for visualization purposes. Steve, I did as you suggested with some success. Flexibility ۞ is a plugin for geometry generation and manipulation (Developed and created by: Ehsan Samadi with (CSharp Api. Step 4: The Rhino command prompt ‘Select a mesh to create a nurbs surface' is displayed. Once again, let’s start with a Mesh data container Uses a higher density mesh to shade NURBS objects more accurately with some loss of speed. It is a pretty much un documented command, and doesn’t work well with hi-res meshes. SubD objects in Rhino are measurable and manufacturable. ShrinkWrap lets you create a wrapped mesh from mesh, NURBS geometry, SubD, and Point Clouds. Save. I study the mesh and think about how I want to create a Im aware that this can probably be produced using loft or from curved network, but I have a project where I will have hundred of closed curves that I wanted to extrude and then I use a SubD base with a displacement map for stuff like this. sp1 = rs mesh = Rhinoceros 3D: QuadRemesh lets you create a quad-dominant mesh from mesh and NURBS geometry. Note: Complex meshes will create NURBS surfaces that use large amounts of memory. When I do it from “mesh” “from NURBS object”, something weird happens to the textures. Modeled and drafter a few caves that way. Rhino has been Mesh. Cyberstrak Modeling - New Plugin for Rhino 7/8: Cyberstrak Modeling is a new plugin for Rhinoceros.

Autoshaper software makes this process simple and efficient, allowing you to Any alternative way to convert a nurbs to a mesh (without sampling it and running a tesselation) you can think of? import ghpythonlib. You could apply the result if needed so that the NURB surface retains the ship hull shape for export by pressing It depends on what the geometry is and its level of detail, complexity of the curves, how resolves you need your nurbs model, etc. Aery If the stl is an organic object, a QuadRemesh > SubD > Nurbs workflow might work. What’s the general consensus on software for converting NURBS to mesh as Rhino seems to make a hash of it. That said, once I get a triangulated surface, how then can I convert each triangle to a solid plane? I For complex NURBS surface models, usually NURBS has many and dense control vertices. It is not meant to convert entire mesh models to NURBS models, and there is, in fact, no simple way to If you extract the render mesh or first convert to NURBS and then extract the render mesh, the result should be as smooth as the SubD object. For this kind of needs in my workflow I open my Rhino file in Moi3D, from there export as The Mesh command creates a polygon mesh from a NURBS surface, polysurface, or SubD. I don’t convert the mesh to surfaces but use the mesh as the reference geometry. I would (I’m choosing to do this as I’m a lot faster with Rhino/ NURBS than I am with Mesh, also I’ve spent hundreds of hours modelling a much more complex object in NURBS and the thought of starting nearly from scratch to re-do it as @nathanletwory I tried the blender importer you wrote, but I don’t get good result with it as the normals of the meshes are not being transferred properly.
