Grasshopper loft brep to surface 3 KB) McNeel Forum Grasshopper. png 1142×463 30. You cannot use a BRep for surface inputs. How to Close a Loft in Grasshopper. How to convert the Open Brep to a Surface? Hey, guys, I was recently working on a building facade with undulating balcony railings, somehow, I run into this problem, I lofted two sets of curves into surfaces(or Brep as grasshopper recognized them) , and then the component "Offset Surface" won't work with these surfaces, because, (pic1) according to GH, "Data conversion failed from Brep to Surface". If we could loft solids (closed NURBS surfaces), it would be easier, perhaps, to just work on Suppose you do a straight loft between “n” curves. MySpace Tweet Facebook Facebook. Version 1. Despite this when a mesh is generated Hello, I want to offset a brep, with the same result as ‘offsetsrf’ inside rhino. You can explode the BRep. As i need my input to stay as a surface for most of the code but just change to a brep to check if The whole surface normal, closed brep, boolean operations area of grasshopper is very blurry for me, does anyone know a resource for this? Fr. So I made a simple test file to demo the problem: What I needed was a set of vertical contour curves made from the input Hi all, I’m trying to create a lofted surface between two curves, and then be able to select each surface separately (Using List Item). From my limited understanding the split brep multiple Hi all, When I loft 6 curves to create a surface, it creates an 'Open Brep' rather than a Surface. 0 KB) I know it has to be a surface, but the loft command gives a Brep which I can’t turn to a Srf. . Also I tried exploding Less control points will result in untrimmed surface, otherwise they will be open breps. Home. : can someone help? this is not a bug. Rhino has capabilities for this that Grasshopper does not. CreateFromBrep(newbrep) is illegal. Thanks in advance! brep_thickness. you can rebuild the Loft (just an approximation of the exact Surface) (right click on the O input of the loft component -> Loft options -> Rebuild (instead of none) or use the Loft options component) 4. You'll probably need this if you want to find areas and centroids of trimmed faces. Download the Example File👇h Done a few searches both here and on the old GH Forum, but yet to find anyone with an answer. If Hi, I am trying to loft between two surfaces as show in the accompanying files. I tried rotating the faces, re-ordering the vertices, mirroring, flipping, etc. 2. I noticed that it outputs an untrimmed surface (even tho it becomes a polysurface when baked). When you mesh a Brep, you actually get an array of meshes. Create a lofted surface through a set of section curves. I am an architecture student working on a project for tomorrow and this is my first real time using Grasshopper. I need to do a ton of stuff to this object, mainly evaluatesrf but none of what i'm trying to do is working because technically this brep isn't a This is how I am generating my four pieces - but when I connect these four lofted pieces into a Brep Join component I just those same four surfaces as a result with no actual joining. Try it out, I’ve made it for this use case actually. Food4Rhino – 17 Oct 17 Pufferfish just starting out with GH and i have a question about lofting multiple curve sets. its the same like the fillet surface works face1: BrepFace, edge1: BrepEdge, domain1: Interval, rev1 Loft options are about the type of loft, whether or not to rebuild/refit the resulting loft surface and -if so- what sort of tolerance to use. I also think I can use network I made this Closed Brep using Loft surfaces, but only after doing some rather strange and unusual things to get the outside surface to work. Hi guys I am trying to put a Square Grid on a Grasshopper lofted surface (should be a brep), but i just don't how to do it. Loft Options (Loft Opt) Select all brep edges that delineate certain faces: Edges from Directions (EdgesDir) Hi, I'm looking for a way to offset a surface into a solid. Hi, I’d like to run the isotim command but before this I want to join these 2 surfaces but I cant figure out how to do this. Thank you! Hi all, When I loft 6 curves to create a surface, it creates an 'Open Brep' rather than a Surface. gh (19. Grasshopper is a social network. Create a loft through curve control points. or (if you think this is a result you Set of section curves or surfaces to loft through: Curve: Closed: C: Closed loft, if true the last section curve will loft back to the first section curve: Boolean: Loft Type: T: Determines how the section curves are lofted 0 = Normal 1 = Loose 2 = Tight 3 = Uniform 4 = Straight: Integer hey guys,im new here so excuse my very basic question. However, when I plug that into a lofted surface, it comes to an error, saying "data conversion failed from brep to surface". As you can see below, I've 6 untrimmed surfaces from my output. If we could loft solids (closed NURBS surfaces), it would be easier, perhaps, to just work on Hi all, When I loft 6 curves to create a surface, it creates an 'Open Brep' rather than a Surface. Jul 9, 2011. Sign In; Grasshopper. The problem I had to work around was how to arrange the curves that create the outer Loft surface. the surface is created after lofting, thus in order to get the surfaces, I am doing a brep deconstruct, afterwards merging the faces. Any help would be much appreciated! Hi all, I have a RhinoScript that operates directly from Rhino itself. Converting a set of loose surfaces into a solid requires the Join Brep component. If you merely translate a copy of the polysurface straight up, you get zero width for the near vertical side surfaces, yet if you extrude each surface in the direction of its normal, you get little overlap at the joints between orthogonal surfaces. (You don't have duplicate curves or zero length segments in there right?) I'm afraid you can't map a component to a surface. This is using simple slider logic to show what I want to achieve but done manually. The two lofted portions were intersected to the bottom of this wall type with SurfaceSplit using an XY plane, and then the two surfaces I wanted to keep were listed into the BrepJoin with the the top and bottom curves of the Brep.

There are two options: 1. So, how to convert open brep to closed brep?. gh (15. If then you are dealing with a polysurface, you can use the A surface can only be a 4 edged nurbs. How to convert the Open Brep to a Surface? Is there a way to create a curve from a surface in grasshopper? I want to loft some surfaces but do not have any curves. Im following along with the youtube video Catenary curves paneling Rhino Grasshopper tutorial by June Lee and im stuck at 5:22 where i connect a loft created from Hi! i am trying to convert my Brep model into a surface so that I can better add textures to it. However, the output of the component is an open brep. Sometimes there are kinks in the lofted curves or other problematic features of your curves setup. When I got an open brep, I will rebuilt the surface under the grasshopper loft command. Degree=1 curves are (poly)lines, degree=2 curves can be used to mimic conic sections such as circles, parabola, and hyperbola, degree=3 is the default for Rhino, degree=5 gives you smoother curves, but each control point matters less, degree=11 is the highest degree Rhino allows. being new to The Brep Split in Grasshopper does not work on a lofted surface. 1 KB) I’ve used ‘join brep’ but when i I know the differences between my work and the video begin when I attach the weave to the loft and when I attach the panel it tells me untrimmed surface followed by numerous open brep while in the video it only says untrimmed surface throughout. I think its because the surfaces are not tight enough connected to the original curves. Loft Create a lofted surface through a set of section curves. It takes it as a geometry but when I try to Hi Omar. 7: 11913 (if during a loft it is difficult to connect a series of curves, Grasshopper creates a brep -so as to give you something- but it is essentially a mesh and doesn’t have the To elaborate, the higher the degree the smoother the curve. So for solve my problem, How can I transform into a only one surface (or maybe maximum 4) ? There are a few things here. I'm currently trying to merge 'em all to ONE surface, or at least one brep because they are co-planars. I've tried joining the smaller breps together as well as doing a boolean brep join but somehow I still end up with a series of brep trim. If the surface has a trim hole, the surface cannot be cast to a single curve, but multiple curves and it will fail. The Morph operation can only deal with plain surfaces. The ‘offset surface’-component does not work with my brep (which is a polysurface). Ok, so what I want to do is subsurface a set of surfaces of a Brep so all edges/panels match, but the numbers can be different on each surface depending on the Grasshopper Surface SYSTEM COMPONENTS. --David Rutten. set of user objects which Hi all! I would like to add thickness to a number of surfaces ( open Brep ). There are two breps in the GH file attached: one is a wall surface with an opening for window, and the other one is the window surface. One surface is a mirror of the other, so I am assuming that the edges that I am wanting to loft between share the same information, i. Not quite grasping what you are describing about the "bottom hole" - I want the top and bottom to be open. Now as a next step I want to delete the upper part of the Brep and I Hi all, When I loft 6 curves to create a surface, it creates an 'Open Brep' rather than a Surface. It feels like something I have had to solve in the past on projects but can’t remember how I did it. Replies to This Discussion Permalink Reply by Mattias Eriksson on January 8, 2010 at 1:31am. I wondering how I select particular edges from a list of Brep edges from two separate surfaces so that I may lof a surface from the extracted edges. How to convert the Open Brep to a Surface? Invalid_Srf. Released on 12-Dec-2023. 5 KB) VG Tim the problem is that your Loft creates a Brep and a Brep consists out of multiple Surfaces (in your case 4 Surfaces) so you need to explode the Brep, if you want to subdivide the surfaces but there you always have the problem that each surface (if it is a big or a small one) is subdivided the same way if you subdived it with the same Isotrim or This really drives me crazy. Now, I want to turn it into one single surface in order to apply transformers on it (derives from this Sometime I got untrimmed surfaces, other will be open breps. --David Rutten A Boundary Representation is a superset of a surface. A file I'm working on will not create a closed brep. Since it is office work, I have internalized the invalid surface and baked the edges in a layer so that you find it (as it is far Hi all, When I loft 6 curves to create a surface, it creates an 'Open Brep' rather than a Surface. I think the component your looking for is 'Map to Surface' Component to map your flat crvs onto your lofted surfaces. Each brep represents the I am currently trying to change the colour of a surface / box according to a slider value as the size of the surface/box is changing, but I am struggling with it. The GH native loft component outputs a Brep. I need to export the surface to . As I mentioned above, the problem is that loft is a Hello everyone, I got a Brep out of trimmed patch and loft. I am taking a list of all surfaces in the project (or a selection thereof), and for each surface I want to access the geometry of the border curve (ie all edit points of I am also attaching the GH file. gh (13. You cannot assign an array of Meshes to a single Mesh. I can join it as one brep in Grasshopper. Difference b/w both the components. You can access BrepFaces via the Faces property of a Brep instance: Dim B as Brep = 'somebreporother. GH1 is able to convert from SubD to Brep out-of-the-box, but with no options available. Change your loft options to include "rebuild" to ensure that a single surface results. Grasshopper at present doesn't understand PointClouds, ClippingPlanes, Blocks, Dimensions, TextObjects, TextDots, Extrusions (Rhino5 only), anything to do with Page Layouts, Grips, Gumballs and I'm sure I missed a few.

I need to turn my upper surface of the Brep into a surface of its own, and therefore split the bottom and the top into to separate surfaces. 4: 789: December 8, 2021 How to convert brep from loft to surface and divide into panels and provide mechanism component. Views: 26448. In the meantime you may want to explode (Deconstruct Brep) your Brep/polysurface before testing the individual surfaces for planarity. hannahm April 16, 2020, 11:52pm 1. A polyline, or a polycurve (a curve with non-continuous Calculate the principal osculating circles of a surface at a {uv} coordinate. In the meantime, you’d need to bake and run ToNURBS. I want to select only the top most faces of these breps. Create a surface After all of my attempts to loft a surface it keeps coming up as an open brep. gh (8. How to convert the Open Brep to a Surface? Hi Larissa, I think you'll get a better answer if you post your *. However, the Loft output from the python component (weirdly)seems to be composed of a Hello, As you can see in grasshopper script, after doing loft, some surfaces are going to open and invalid brep. The brep Hi all, When I loft 6 curves to create a surface, it creates an 'Open Brep' rather than a Surface. By default, the Loft component will create an open Loft, as shown on the left. ) Added by kgm 0 In fact in the rare occasion where trims are short paths (in a way the case with planar stuff and convex 3-4 edge holes) you can approximate the underlying surface as an untrimmed one using short paths, division pts etc etc. Cheers. A joined collection of surfaces is called a BRep. I hope someone can help. If anyone can help me with this problem it would be greatly appreciated. I’ve tried Solid Difference, Region Difference, Mesh Hi all, When I loft 6 curves to create a surface, it creates an 'Open Brep' rather than a Surface. Then to create your openings try using 'Item' Compment to select the crvs on the surface you want to cut with then use look at 'Split Srf' Component to split you Lofted surface then use a Look at 'Cull index' Component to remove I am trying to do a loft between 2 curved surfaces. Data conversion failed from Text to Surface brep2surface. U(Surface Space U Extents): Not sure, is it the U Domain, or from the Domain^2 Components? V(Surface Space V Extents): Same issue above for U. Hi, I’m trying to use a script that reads a surface and projects a triangular grid onto it, however the surface that Im using wont be read by grasshopper, I’ve booleaned them together and joined them and rhino reads it as a singular surface but grasshopper simply doesn’t? and refuses to allow me to put it in the script. 3dm (749. Then you can [merge faces] to have a clean planar surface. is there any other solution for that? Best About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features NFL Sunday Ticket Press Copyright The surfaces are curves which got lofted or patched.

I am trying to split this Brep? with a plane and everything seems to work ok. brepnormals. 7 KB) Invalid_Srf_2. however, the compound I am using, analyzes every surface separately. I have two lists of data with 10 extruded rectangles on each list. I'm also linking my . Peace, J . 0. Thus: because of casting magic it works - not because you can actually create a loft between two surfaces. Basically it is a closed surface generated after lofting a series of oncentric 3-point arches. 20: 19958: November 23, 2017 Grasshopper. 2 KB GH_Trim_surface_with_brep_2019Nov11d. I'd like to do the same thing that Surface -> Offset component does, but "fill" the region between the original and offset surfaces to create a solid object. I would like to get a trick free grasshopper script, because about 120 students needs you use it. I know on the Python component input you can set the data input type from surface to Brep if the code in your python such as BrepFace. I exploded the faces, but I'm not sure how to filter the list component to only select the top ones. In other words I can only Hi Robert, Generally Rhino splits extruded, lofted and swept surfaces at creases by default -- therefore, so should do Grasshopper, too. If you don’t want use Mesh Brep . A am a beginner with Rhino/GH, coming from an engineering Background and SiemensNX and Ansys Ultimately my model is uploaded to shapediver, where Selecting only the top surface from a list of breps. Grasshopper. Forums/Support Or just use the surface border curves and the region difference component. I’m trying to work with curves created from intersecting with a plane and then trying to loft the curves. Both the Explode(BRep Components) and Brep Wireframe would extract the Hi! I’m new to GH so this may be an easily answered question. This might not be the case with some imported geometry or, especially, if the command _CreaseSplitting in Rhino v5 or this plug-in is used in v4 (I do not recommend it). Search. I found a way using weaverbird plugin but I have to convert my Brep on a mesh. However, i am not able to create a clean loft with the contour curves, which is probably due to the arrangement of the control 3. a loft doesn't necessarily return a single NURBS surface. Ok, so what I want to do is subsurface a set of surfaces of a Brep so all edges/panels match, but the numbers can be different on each surface depending on the length or something similar. Hi Larissa, I think you'll get a better answer if you post your *. brep join dosnt help me. Thanks a lot Grasshopper is a social network. gh file with the curves internalized. Now I wanted to make a mesh out of it and smooth it. It seems to be generated in the lofting process, I only want the surface to be displayed without this line. It has changes in elevation, arcs, and changes in profile. Permalink Reply by biboarchitect on December 27, 2011 at 5:42pm. It was created by lofting through 3 curves which are filleted (fillet'd??) polylines. If I'm now starting to learn Grasshopper and already encounter my first problems. gh file The problem is that your Loft is producing a BRep, or polysurface, instead of a single surface. Hello everyone, I’m a bit stumped at the moment and can’t get any further. Permalink Reply by Krish Girdhari on January 18, 2012 at 5:12pm If the surfaces are planar, you can extrude them using the surface normal vector - doesn't work so well with non-planar surfaces but can come close. it looks like you are A BRep is the equivalent of a polysurface. In Pufferfish there is a loft component that can keep things that would normally be breps as single untrimmed surfaces. I’m unable to get my complex brep to offset. I think something to do with the control points in the drawn curves. gh (84. I can't seem to figure out what I'm doing wrong. If you don't already have the outlines, you can get them with BRepWireframe. if i want to divide a brep by a surface,what should i do in grasshopper to realize this i used ‘deconstruct brep’ to sort out the surfaces of the brep and i did it again to sort I know the differences between my work and the video begin when I attach the weave to the loft and when I attach the panel it tells me untrimmed surface followed by numerous open brep while in the video it only says untrimmed surface throughout. e "0 Planar Curve" on the loft has "0 Planar Curve" as its mirror. Hi all, I have created a hexagonal grid with attractor points that I would like to attach to a curved lofted surface. I have the Brep on the left, and I’m trying to subtract the Breps on the right so I’m just left with a latticework. I am working on making a parametric facade and having some so if you want to fillet surfaces you have to extract the edges of the two surfaces fillet the lines join them and loft them again and you have the new filleted surface so it is also possible to fillet with variation of the radius. However it will only work if the edges of the surfaces you're joining are within tolerance of each other Rhino and Grasshopper’s Definition of an Open Brep. Is this possible? Is there I’ve been trying to do this for three hours now. " It consists of several different surfaces. How to convert the Open Brep to a Surface? Turn the surface into wireframe brep, repeat for offset surface, graft data on each wire preb component, use the loft component on each brep to create the necessary loft on the window holes closures! Permalink Reply by Hi Frantz, without your files we can only guess of coarse, but my guess would be that your loft resulted in a polysurface/brep, because of kinks in the curves you lofted. I started with a part of @laurent_delrieu 's script from my last thread, to get a “low poly” mesh at the Another approach will be same as Raul said, make a closed brep with floor surface, move windows centroid with their own normal vector, check which normal vector are directed to the inside with brep inside, pick the wrong I want to use a brep join component to join 2 breps into one closed brep as wall surface for thermal analysis. Hello, I have a list of breps selected of various dimensions and faces, none matching. but the problem doesn't solve. A loft is created. The key thing I think I have learned about geometry like this, and more specifically about Lofted geometry, is that if you give the Loft function a bunch of complex curves to match the edges of, the resulting Loft surface Hello, I’m trying to split this singular brep with multiple surfaces which have been constructed on a series of planes. 1 KB) Hi David, So, I have attached here the files. If you [Explode] your BRep it should give you the constituent surfaces. So this: newmesh = mesh. Selecting only the top surface from a list of breps. Faces(0) BrepFace has a DuplicateFace() method that creates a new Brep that looks just like that one face. A brep is a trimmed surface or has multiple faces. being new to grasshopper and all. First of all you can copy paste a screenshot into a A BRep (short for boundary representation) is a 3D modeling umbrella term that typically includes both surfaces and polysurfaces - so if you have an open BRep from a GH loft I've tried rebuild,use interpolate and poly-line to make new curves and some other ways. Is there anyway that I can prevent the surfaces from exploding when unrolled? I need to unroll surfaces with curves In this Rhino Grasshopper Tutorial, we are going to model a parametric circular Loft surface by using the Graph Mapper Component. See image below. How to convert the Open Brep to a Surface? It looks like it’s slated for Grasshopper 2. Just plugin a SubD type into a Brep What I actually want is one main brep with the smaller brep series taken out as a singular brep; aka one brep with multiple holes through it. Any help is most welcome. I know the differences between my work and the video begin when I attach the weave to the loft and when I attach the panel it tells me untrimmed surface followed by numerous open brep while in the video it only says untrimmed surface throughout. These four surfaces form the ring geometry I need, but I need it as a closed Brep to be able to perform Boolean Differences on the geometry later. I need to do a ton of stuff to this object, mainly evaluatesrf but i want to make surface from open brep. It is called Unsplit Loft Surface. In Deconstruct a brep into its constituent parts. Please Help Calvin Hi I want to change the loft the surface to mesh, but two of them show that is open berp and can’t change to mesh. So I am trying to find a similar way to rhino BlendSrf command for example in Oh, actually, try [solid union] instead, because your breps are overlapping. It can contain more than 1 surface and additional trim data. I’ve tried referencing it as a brep but the script A Brep is a collection of one or more surfaces where each surface can have trimming curves assigned to it. iges but the arch line is visible and does not fit the purpose. I've read some posts on same issue, and it's said that happens as the lofted surface does not have continuous curvature and it is splitted up into different components in grasshopper. i have populated a surface with a grid of circles, and then offset each circle. As you can see, its made of 8 different surfaces. Do you guy know why grasshopper won't take my lofted surface as a surface. A BRep (short for boundary representation) is a 3D modeling umbrella term that typically includes both surfaces and polysurfaces - so if you have an open BRep from a GH loft component, chances are it's a surface. As far as I see in Loft Invalid Brep HELP!!!! Posted by Archiheart on November 29, 2015 at 4:53pm in Discussion; View Discussions; Hi. right click the "S" input to the subsrf component in your uploaded definition and choose "graft. In a closed loft, the first and last input curves are connected to None of my “fast” tricks worked for orienting minimal bounding boxes in this case, due to irregularities in the curves. Essentially it is an elliptical wall "solid" I'm trying to make. S(urface to map to): I'm assuming the loft component which represents the curved surface. To elaborate, the higher the degree the smoother the curve. So you need to decompose the Brep and extract Hi all! I have 2 surfaces with some holes in each of them and I would like to create a closed brep. Thanks! Grasshopper. join surfaces. I thought it would be quite simple, but I tried using the gradient tool i don't Hi everyone, I’m wondering why Rhino 7’s Loft command in Grasshopper doesn’t create simple surfaces (even with the Rebuild option), just breps and with horrible Hi all, When I loft 6 curves to create a surface, it creates an 'Open Brep' rather than a Surface. by Aaron. I manage to get the points on the Brep, but I can’t go any further. So I would like to ask you if there is another way to thicken Brep without converting the Brep to a mesh object. These curves produce an Open Brep I’ve split a Rail Revolve surface using lofted surfaces and am trying to subdivide the resulting split surfaces. Rhino/GH decides to create multiple sublofts and then join them. You should be to connect your Loft component output into the S input of an SDivide component to perform the surface subdivision. Less control points will result in untrimmed surface, otherwise they will be open breps. See attached rhino and Hi guys. Permalink Reply by Bartosz Kozlowski Image to 3D Point Cloud using Rhino Grasshopper and Depth Estimation ZoeDepth (WIP ver. If your brep contains only simple faces (faces without holes or difficult curvature, having 3 or 4 vertices on their outer loop only), you can use the Simple Mesh component. I tried to use deconstruct brep to get the faces and to merge them all. My problem is the lofting follows a certain order. How to convert the Open Brep to a Surface? I was directed to ask a my question here, I’m stumped. mac. How to convert the Open Brep to a Surface? Actually, the loft between two surfaces works because a surface > curve cast will return the singular curve. We can see that all the sides are rectangular planes. IsPointOnFace but you are inputting a surface but how to you do change the type from a surface to Brep with Rhino common code. gh file Recently using the Loft from Rhinocommon on some polylines. 8 KB) By the way, Srf SL is a cluster I wrote to return smallest and largest surfaces based on edge length, My question seems to be simple, but I can't solve it by myself.

W(Surface Space W Extents): Same as U and V Hi all, When I loft 6 curves to create a surface, it creates an 'Open Brep' rather than a Surface. gh file If you have a Brep/ polysurface in Rhino, you can select a closed loop edge, run the FilletEdge command, and add handles at various points with different radii to make a Hi all, When I loft 6 curves to create a surface, it creates an 'Open Brep' rather than a Surface. You can see the input to Loft from the first, but if I attempt to add the second surface to the ‘C’ input on the loft component the first input goes away. Create a loft fitted through a set of curves. david@mcneel. Dim F As BrepFace = B. How to convert the Open Brep to a Surface? a loft doesn't necessarily return a single NURBS surface. How to convert the Open Brep to a Surface? Hi all, When I loft 6 curves to create a surface, it creates an 'Open Brep' rather than a Surface. Currently I've found a solution which works using the Extrude to point command but it is far from elegant and not to mention pretty slow in execution. Actually I thought it should work with the loft component and brep join, but I can’t get a brep to work, can anyone help me? ImageSampler2. It works on most of the split surface sections but not on the last one. How to convert the Open Brep to a Surface? this is the surface i have. Hello everyone, and thanks for taking the time to read this. Now if you use “Deconstruct Brep” to get the faces, and plug another Hi I am using the attached GH component for unrolling surfaces/breps with curves and points. So I ended up replacing your C# component with an Anemone loop, checking angles from “-x/2” (-45 Hi, what is the most efficient way to create a single surface out of a polysurface? the brep I am working with was originally a mesh which has been converted into a polysurface, and now I need this surface to be a single surface. Any help would be appreciated. i would like to then loft each pair of curves, but i can't figure out how to separate them into pairs since 'loft' just takes a list, as opposed to 'curve a' , 'curve b', and so on. gh (40. Then BRep join all three surfaces. If you look at the tooltips of the input parameter for the Loft component, you'll see that the first one takes all the section curves and the second one takes the options to be used to make the loft. For Rhino and Grasshopper, a closed Brep, is set of joined surfaces that describe a fully enclosed 3D volume. If you explode the resulting B-rep, you get “n-1” surfaces. I have two surfaces that are almost on top of each other and I want to create a closed brep. Please consider disabling your ad-blocker to support this website! 🔑 If you merely translate a copy of the polysurface straight up, you get zero width for the near vertical side surfaces, yet if you extrude each surface in the direction of its normal, you get little overlap at the joints between orthogonal surfaces. Otherwise, an offset surface with edge connections can work, though there may still be issues. How to convert the Open Brep to a Surface?
