Any ideas would be greatly appreciated, thank you! Rhino is exporting a good mesh but your exporting a bunch of them and they are overlapping. I can redesign it and probably solve it with a workaround, but why this Is it possible to simplify the Quads on the SubD that i generated (grey one) out of a mesh and make it look more like the green one (credit to @martinsiegrist). Note using the Loose=Yes option on the Project command will keep the curve structure of the input curve on the projected curve, at the cost of not necessarily being very close to the surface. Triangle surfaces will be planar and trimmed or not according to Hi folks, I have a question regarding smoothening topography surfaces, for a landscape architecture project, I’m currently working on. However - after dividing the topographical surface into certain segments, I’d like to smoothen/simplyfy the new surface areas, so that To achieve a watertight model, you need a closed polysurface. Hi there, I was wondering whether it is possible to simplify a loft (or reduce its size). gh (24. The original files are attached. 24149. Optional.

My model Explode a polysurface into individual surfaces. I would split off the straight part on the right from the curved part - make a line where the stright part is and BlendCrv makes a pretty good thing if you blend to the line for curvature and use the Point option for the far end: You don’t need to explode a polysurface to be able to run ToSubD on it. My purpose for simplifying is to redivide the surface with Efficiently editing polysurfaces in Rhino 3D can streamline your workflow and save you valuable time. The curves on the polysurface will probably need rebuilding to simplify using Rebuild, RebuildCrvNonUniform, or FitCrv. 1452: September 25, 2017 Need help projecting curves on unrolled surface. ) I was able to get the pipe trim method to work well in creating a continuous surface between the subd loft and the nurbs cuff/tab surfaces on either end of the boot. Throughout these lessons we'll focus on a process-based approach to the creation and manipulation of complex surfaces in Rhino. Zooms onto the polysurface that relates to the tagged problem. I want to export it into 3D max for rendering purposes. Hi All!! I am building the hull of a sailboat. Step 4: The Rhino command prompt ‘Select a mesh to create a nurbs surface' is displayed. this will fill planar holes with solid surfaces to make an overall manifold (solid) model. If I try to pipe around Hello, I have geometry data that is an open mesh. and then what, I have intersecting polysurface with two planes; and I want to trim the polysurface Hi there, I’m still learning a lot about Rhino and the basis. Note: This is an example of pre-picking input for a command. Rhino says it is a polysurface when selected ^ we’re talking about extending the polysurface edge as in modifying the polysurface. You can snap and select points in the Hello, so I have a plane and a mesh and they intersect, now when calling Intersect. com” and import it into rhino. ProjectCurveToSurface (strCurve, arrSurfaces, arrDirection) Required. And I’m uncertain still in that regard. I’ll very Rhino 3D Tips Tip of the Day: Efficient Editing of Polysurfaces in Rhino 3D Efficiently editing polysurfaces in Rhino 3D can streamline your workflow and save you valuable time. ) I have figured out the Rhino commands to use: QuandrangulateMesh UnifyMeshNormals MatchMeshEdge ToNURBS MergeAllCoplanarFaces Now I am trying to replicate this process Hi, this is Phil from Simply Rhino and in this video, we’re going to take a look at developing and flattening surfaces in Rhino. 3dm (403. m_L(26) loop is not vaild. Software required: Rhino 5. 8. I have tried OffsetSrf which gave me something hollow inside, and ExtrudeSrf which basically break my polysurface extrusion into hundreds of seperate units and I can’t BooleanUnion them. In the list of display modes, select Is there an easy way to simplify the meshes as seen in the file? The 3D shape has to be out of multiple flat surfaces. Traditionally SubD objects are mesh based and lend themselves well to more approximate types Since Rhino works on curves instead of meshes, a polysurface is a multipart surface. I’m working on a project and a lot of you have been very helpful. Hello - the only way that comes to mind is ExtractControlPolygon QuadRemesh with SubD output. i think the best solution is the availability to assign attributes with options “by parent” (parent for polysurface edge would be polysurface itself, parent for Create a set of cutting planes, and then Intersect the cutting planes with the polysurface. I must mention that I have tried with The analysis reason may be the existence of Invalid polysurface in the original model. The identifiers of the surface or polysurface objects to project onto. by Josh Lobel. Array. I joined the surfaces and converted from a mesh to a polysurface but can't find what I'm doing wrong here. 3dm (3. If it’s not, it could be a bug - quite rare, but possible. Step 4: The Rhino Hi, I have a very huge work to export from rhino to solidworks. I use Rhino 7. Faces in the resulting polysurface correspond to the tangent sub-curves in the input curves. A polysurface consists of more than one surface joined together. com/us/app/video-training-courses-from/id418130423?mt=8http://www. To make this not non-manifold, you need to change the shape, the simplest thing is to Hello, I am a newbie, and I am trying to to convert a mesh to a few surfaces or solid, instead of that I am getting an useless polysurface. r/rhino. Rhino for Windows. I trying to think of a way to simplify surfaces. It is the equivalent to creating multiple meshes to form an object and then stitching them together to form a single mesh. I am an active user of spaceclaim and solidworks but have never used Rhino. I also discuss some simple ways of modifying meshes, such as splitting, A polysurface is as it sounds, is a group of surfaces joined into one entity, you can extract these surfaces by using PolySurface. 2: 44442: July 5, 2013 Home ; simplify polysurface (Voronoi) Posted by Marinus van Hall on August 24, 2014 at 10:42am in Discussion; View Discussions; Hi there, I was wondering whether it is possible to simplify a loft (or reduce its size). 12 Convert to lines and arcs, simplify lines and curves, and closed open polylines (4:12) 5. b) Build a single surface using the available data. The default value is None (0). Cheers! Rhino 7 introduces powerful new SubD modeling components in Grasshopper. IsPolysurface. I can join them together in rhino to re-create the closed polysurface with 0 naked edges/manifold edges that I had before converting. I just want to ‘bridge’ (as it’s called in Blender and other software packages) the two holes you can see in this image: so that I end up with a tube connecting them together. You can try the Rhino 7 WIP here https://discourse. He did just that but i here’s the deal, object is in mesh, and when i try meshtoNURB the outcome looks terrible. stl, I don’t get the dialogue box to adjust - offset settings? on the other hand, When I export an extrusion - polysurfaces (in blue), I do get the STL Mesh Export Options? Is it simple as “you cannot adjust a Mesh that’s already a Mesh”? But that’s why I would like, adjust the density of a mesh for instance. Rhino has to calculate two edges instead of one. Hi all, I have imported a . To begin the Thank you. use WireCut rather than Split or Trim. I pasted a picture of A polysurface consists of two or more surfaces that are joined together. My question is quite simple, how do experienced rhino’s users quickly edit poly-surfaces such as boxes, cylinder, etc without remaking the geometry. In case you’re using Rhino 6, you have access to Rhino 7 / WIP You can use the Quad Remesh command and turn your polysurface To achieve a watertight model, you need a closed polysurface. but I don’t see that helped. I need to create walls, that extrude In this video Phil Cook from Simply Rhino takes a look at SubD, or Subdivision Surface Modelling, that is being developed for Rhino v7. If it’s pretty simple just make a surface cutting through it, split it into two and then move it and make another solid connecting Find complex mesh model on “3dwarehouse. The possible loft simplify methods are as follows: Value Hello, I attach a render with a problem with a curved polysurface that is not smooth. If I try to pipe around Hi I have a Rhino model which is made up of all polysurfaces. dupBorder Version 8 (8. Thus, paneling using uv-directions may not continue the paneling pattern In order to reduce file size for SW, I remove most of the base and recreate a new and much simpler one in Rhino. I tried all rebuild commands, but it work depends from lenght How to rebuild (reduce control points) from curves but independently lenght. You can use the point cloud object to group any number of individual points into a single object, minimizing the amount of storage in the 3DM file and maintaining performance. However it seems no matter how I manupulate it it just won’t give me a nice solid thin layer. Hi All, I have previously imported Rhino 5 files successfully into Revit but am having trouble with a topography file supplied to me for a project. any help would be greatly appreciated. seat3. org" by Prof. Verifies an object is a polysurface. please see screenshots as to what I’m trying to achieve. Help Needed So basically i want to proyect or move a bunch of polysufaces to different Hello - with the curve on surface you cannot do this on multiple surfaces, but using Project/History as described you can join multiple surfaces into a polysurface as the target. 0 mb) 1CLOSED. 7: 440: September 14, 2018 Can't split surface. After import, the geometry exists in Rhino as a series of faceted polygons grouped in an open mesh. Hi Cameron - I’d say @John_Brock was on the right track- the three straight sides are fine - Explode the curve and deal with the top bit which is a mess. I tried to make this polysurface with trim and also boolean but the result is the same. 3dm (175. ' arrCurves - Array, The identifiers of one or more curves to unroll. I thnk I’d probably model parts like this at a tolerance of . At the options - mesh - I have already changed it to smooth and slower. end of brep. Master the tools and techniques to modify your 3D model efficiently. 001 rather than That a pretty nasty surface. Select the green sphere. Hi, I'm new to Nurbs modeling and overall Its a great way for accurate modeling. McNeel Forum How to handle Invalid polysurfaces. It’s too many to patch by hand, so I wanted to get Following up on this previous post: (I’m trying to create a CV boot-like attachment from a subd loft connecting an inner cuff and 4 outer tabs which will mount to the device. ProjectCurveToSurface (strCurve, strSurface, arrDirection) Rhino. Rhino for my absolute tolerance in rhino is set to 0. Hello. I had no luck importing the . The Hi there, I’m a beginner Rhino user and still trying to understand a quicker way to edit poly-surfaces rather than creating the geometry from the beginning as well as undoing trims. infini Hi everyone , i was wondering is there any way to convert a true subd model to surface in the way that catia and siemens nx are doing in rhino ? those softwares consider each subdivided polygon as a single surface rather Hi All!! I am building the hull of a sailboat. Non-Uniform Rational Basis Spline (NURBS) is an accurate mathematical representation of curves and surfaces. Loop 0 is self intersecting or overlapping. Create a surface based on gray-scale color values in If a polysurface is valid and has no non-manifold or naked edges, it should be considered “closed” by Rhino. mesh. To simplify things: Let’s assume that the array of polylines is always of the Length = 1, so how can I create a surface from a polyline? " Polysurface 1610f45f-94c3-4d1f-a65f-47521181a0fa , Face[24] is invalid. I tried with flow along curve and flow along surface and the polysuface ends in a mess. Click Single Surface from mesh from the Resurf menu or type RsMesh2Surf at the Rhino command prompt or click icon at RhinoResurf toolbar. 3dm (56. igs and . What I have noticed is that the curved polyline that I extruded has more than three control points. Hide all curves if Hi guys! I was wondering, how do you tilt a surface/polysurface? I made a simple box and what I want to do is to pull a straight line on the roof/top to the bottom in a half distance. The problem is that the file size is quite large (around 500mb) and I can see that some of the polysurfaces are made up of a lot of polygons. Hi guys I have this polysurface that I want to simplify the number of faces it has, and instead of having millions of tiny faces,have less faces ( optimize it) There’s no way to simplify a nurbs polysurface without manually rebuilding it or taking it out of the nurbs realm? I tried the rebuild command (Isn’t it supposed to work on polysurfaces?) But it wouldn’t work on this object. com/ COMMANDS: MESHREDUCEMESHMESHTONURB How can I rebuild or simplify this polysurface so that it’s light and editable while preserving the overall shape? Rhino Help_Simplify Terrain 1270×557 184 KB. Any ideas? Thank Hello all! I am having difficulty cutting a closed polysurface in half. So plz bear with me. I guess you can run the tosubd command, but it won’t do what you are expecting. Explore other Rhino 7 enhancements for Windows and Mac. First, we need to weld the mesh faces together into a single closed polysurface. JJerry (JJerry) November 2, 2023, 4:03am 1.
