The only way I have found is to split brep multiple multithreaded c#. The process should be to first divide the group of BReps into those which cross the plane and those which don’t. P. gh, 15 KB. 3. Share. Resulting untrimmed single unsplit extruded surface When you bake this surface into Rhino it will become a usual polysurface (Brep) which is split at its kinks if it has kinks, unless you first run the command CreaseSplitting in Rhino's command line and turn it off by switching it to No. three tips. Split method, however then I have to iterate through faces of the Brep and then combine it in one Brep. For some reason, I can split the left Brep/brep intersection. gh (601. com/app/bi Brep plane split component. Pufferfish mainly uses parameters and factors for inputs for more custom control over operations like tweens and grids as opposed to grasshoppers usual division count inputs. The Patch component is a bit of an unpredictable component. Sadly, this functionality has still not been I have so many problems to split multiple Breps with multiple planes, and I don't know how to solve this matter. ) Using the surface, create a Brep using Surface. “Brep/Plane” will intersect a set of planes with your surface or polysurface and extract the resulting curves and points. If this surface has kinks you can turn grasshopper tutorialgrasshopper surface split grasshopper surface grasshopper Perforated Surfacegrasshopper rhino 💾 Apps/Files to do this tutorial:→Bifocal Description. Trim a curve with a Brep.

Split it with geodesic lines and then flatten it into 2D curves. Here a random orientation of plane passing through the center of mass of the Brep. To create an aesthetic view, the waves should be able to flow from one panel to another. The other method which I've used (but was kind of a pain) was RhUtil. I previously posted about a brep | brep issue I was having but that has been resolved. Yes I may divide the SubBreps to add mullions. gh Surface Split from a BUNCH of curves vs with a BREP. Rhinoceros を使用して Solid を作成し「Brep コンポーネント」に Set します。. Good luck and cheers! I’m trying to split this singular brep with multiple surfaces which have been constructed on a series of planes. Curve. (surfaces will automatically be converted to planes) Or, if you want a more specific intersection, use Brep | Brep (BBX) component, but it could be somehow more tricky sometimes (or slow, heavy). If you can get curves rather than closed Breps, there’s a tool in Grasshopper called Region Union. 3 KB) anon39580149 June 5, 2021, 8:10pm 6. Dear Dale, Thank you. you need the python for grasshopper plugin, Hello, I’ve run into an issue while trying to split a set of closed curves with a plane.

Example: Permalink Reply by Vicente Soler on November 13, 2009 at 6:35am. you need the python for grasshopper plugin, This is great, but is there away to split with curved surfaces? Obviously the split brep component works, but it is missing the 'split' surface. Split the curve at the intersection point. thanks. SB. If you do this, you can bypass all boundary checks. brooks (Brooks) December 20, 2023, 7:10pm 1. You could also switch to Brep|Brep intersections and create planes (or ‘planar surfaces’) that are finite in extent. pass in two flattened arrays. there is no method for splitting a Brep with a Plane. I notice that those would appear where the curve would “overlap” (it’s sort of a C-shape curve, so the sections would appear on the along the ends). For those that dont, divide Name ID Description Type; brep: brep: brep To Split it: Brep: plane: Pl: plane: Plane: Tolerance: tol: Tolerance: Number: Union: Union: First Union then Split Brep Split with Brep. W2-report. I have been looking at the Brep Typopolgy let's see if this one help me i think you need to project a curve on sphere and then use srfsplit with that curve. This would transform the joined polycurve into a single continuous curve with a point count and degree count of your choosing (you probably want 3 degree curves). There's a little bit of give and take here Grasshopper. gh (33. I have a portion of a spherical surface with multiple curves (obtained by brep- plane intersection), and I want to find and select all the intersection points of the grid. you need the python for grasshopper plugin, I'm basically triying to select only the end faces, whatever their number, and not the main body of the brep. Hello. Brep. Another problem, when the fonction is ok, the draw in grasshopper is ok, when i bake i have only a litte My take was the following: - create a planar surface from the shape curve - find the point on the curve - decide on split direction - add a splitting curve in direction, with boundingbox max as lenght - extract curve - convert surface to Brep - split Brep using Brep. 本次更新结束,下一篇将更新 「Grasshopper 知识点科普系列 3 : Panel Brep plane split component.

What's the most robust way to split one surface with another surface? The Simplest Method I found is to create a Box based on the PerpFrame and then extract two faces to get their centroids and then create a Plane from Three Points. There are a few stipulations with using this. 3 KB. Interestingly enough, if you move the reference curves the output will vary. This replaces the second Sweep 2 with Offset Surface: PRUEBA COSTILLAS_2020Aug29a 1772×416 316 KB. gh 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. This is using simple slider logic to show what I want to achieve but done manually. (2) in the third picture, a vertical surface cannot be successfully used to cut a brep. Intersected. I have managed to get something working well using a VB component, with the short script below, but this falls down for some of the breps, as Brep plane split component. ammari. I am attempting to create a trimmed surface patch with a planar boundary, but when I use the Plane-Brep Intersection curve to trim the Brep, it deviates from the plane substantially so that I cannot Brep plane split component. Attachments: cutmask2_reV3. Optional number which will explode the unrolled polysurface (Brep) faces as a disconnected linear array spaced apart by the amount of the number, unrolled points and curves will follow. Brep is short for B oundary Rep resentation. Ci. I'm trying to create an offset face like We’ll start with the basic Surface Split component sequence: we’ll add a Surface Split (SrfSplit) component, and connect our base surface. This creates a proper bearing area. I am doing a solid Split experiment and have found several problems. As the circle on the image, there are no curves on the half Hello. The closest one I came across was 'Trim Solid' Grasshopper 1 Define initial geometric object . I. the new data tree should be based on the plane but also on the a,b,c containers. Now as a next step I want to delete the upper part of the Brep and I dont know how. Method & issue: I try to create cut plane to divide surface by using Brep/plane. The script takes your Breps, finds the face with the lowest z-coordinate center (so the bottom face), I'm now starting to learn Grasshopper and already encounter my first problems.

This needs to be a box, because i need to trim surfaces in multiple planes with the same cutting shape. you need the python for grasshopper plugin, But you didn’t graft inputs so one goes down and the rest go up. Split curves on the inside of the trimming Breps. Added by Randolph David Prime Jr on February 10, 2018 at 11:43am. You need to do an intersection. one for cutting, one for object of cutting. Let’s go through the process of trimming a curve step-by-step, using an example to illustrate how it works. 0. Sometimes this fails and the surfaces doesn’t split which kills everything else down the line. gh (13. I'm trying to split a joined list of surfaces by a list of curves but I cannot find a component that does that. I am trying to split a Brep(converted surface) using a plane which is based on the UV values of the surface. In this tutorial, we will generate slices from a 3d model and arrange them next to each other in one layer. Split a curve with a Brep. limpens) February 27, 2023, 1:21pm 1. If I have one closed volume and an arbitrary number of single surfaces that fully intersect it, how do I get all the split parts - like BooleanSplit or even Split would Hello, I'm trying to split a group of stacked breps with a surface plane intersecting through the middle of them, but I'm not sure how to proceed. image. flip cutting surfaces to pick what side you want to keep. These are kept, brep joined, and then face-merged to give simple planar boundary surfaces. Brep, obj_refs) If rc IsNot Result. GetMultipleObjects("Select breps to split", False, ObjectType. With the first brep-plane intersection i get the horizontal curves, with the second the vertical ones (image 2); I tried with the multiple curves intersection And usually remeshing in this kind of situation, you'll need more dense mesh subdivision where there is more curvy area of face, but yours is not. Grasshopper Commands - Brep/Plane. gh (14. Idea to Explode Brep and than delete unnecessary surfaces is the overkill. The optional cap is a single face with one circular edge starting and ending at the base vertex. 6 KB) 1 Like. Architecture Drawings. Makes a Brep with one face from four corner points. Here is an example geometry: Project on plane. Arrange slices in a plane. What I need is to keep the list of Breps resulting from splitting. Their orientation is always horizontal on the world plane, but other than that, it varies. you need the python for grasshopper plugin, Grasshopper. 06. Bas P. I like to treat them as groups of surfaces with some smart logic There are many ways to trim a curve in a Grasshopper definition, and you will need to use a different strategy for every circumstance. 右上にあるコンポーネントが「Galapagos コンポーネント」となります。. Add the ‘Patch’ component and connect the “naked edges” output (graft the input first). This mathematical precision allows for a more accurate representation of complex shapes and contours. oscar. I should mention that the inputs B and C need to flattened on the Final Component. What I am trying to do is to scale down the brep it in its own plane(s) with the final difference between the original and scaled breps being a width of 0. There really isn't any way of doing this with the SDK, and the recommended method is to extrude the curve to get the brep and use that to split the original brep. It splits from one Brep I started over and split the BReps with a plane. Merge the intersections and the differences to get a list of split solid objects. you need the python for grasshopper plugin, Name ID Description Type; Brep: B: Brep to split and mirror: Brep: Plane: P: Plane to split and mirror: Plane: Selection indices: S: Select the result of the split: Integer A few points: Your breps look a little badly defined. Resulting in (nicely) two Breps when using one cutting plane. RSS. Try using Split Brep instead. Any help would be great! Thanks Jack Split Breps. In general, having the perimeter of your cutting surface be identical (in top view) with the brep you want to split is not a great idea. you need the python for grasshopper plugin, Trims a Brep with an oriented cutter. you need the python for grasshopper plugin, Brep plane split component. Constructs a Brep representation of the cone with a single face for the cone, an edge along the cone seam, and vertices at the base and apex ends of this seam edge. That component is used to split a surface in fragments by using curves. limpens (o. ToBrep. The best thing to do would be to use the ReB (Rebuild Curve) component in Grasshopper (or run the Rebuild command in Rhino). Explode. sampokorea (Archisong) November 7, 2018, 7:51pm 1. This can be quickly done with the Grasshopper plugins Weaverbird or Element* and is a common scenario for 3D printing. The curve isn't planar (within tolerance). 041232×811 95. If you insert multiple breps, you should get individual branches with the split breps in them. Delete the resulting curve segments we don’t want. Split one brep with a bunch of others. In something like Solidiworks or Onshape, I would extrude the projection with “up to next” to fill in the space under the brep.

Permalink Reply by Gui Talarico on March 28, 2014 at 9:39am. But one can always call the command directly, then send the results to grasshopper: Check the attached component. I tried: 1) Just cut with plane with Split command, but it says "Did not succeed" and doesn't do any difference except adding plane division in the middle of the overall surface. Start here! Angel Sebastian. This gives me the desired In Grasshopper, you can either use the Mesh Split component to split both meshes with each other and join these into closed (mesh) volumes or you can use Mesh Split Brep Multiple. I have tried using a solid difference between the set of Breps and plane 1. “Brep/Plane” will intersect a set of planes with The goal is to cut the Pipe with boxes on surface with a yz-plane. tomialori8 (Tomialori8) August 29, 2020, 9:13pm 1. NOTE: obviously you sould I found an easy method to “boolean split” 2 Brep objects with Grasshopper. In this Video tutorial, I will be talking about how you can use "Brep/Plane" intersection tool to produce geometry. Hello, I would like split multiple breps with each other and it to output each intersecting volume as a seperate brep. I started with a small example first to find a way which I can generalize it later (the image is attached) For that reason I am using a longer approach based on Brep / Plane intersection because the Brep / Brep or Region Intersection only works if the surfaces cross. Edit: Looks like you are using “brep:brep” which gives you curves of your intersecting breps instead of splitting them. In this video I try to Brep plane split component. Inside. Params > Input > Value List Sets > Sequence > Cull Pattern Surface > Analysis > Brep Edges Sets > Sequence > Sequence Mesh > Analysis > Mesh Inclusion Millipede > Stock > Material Surface > Primitive > Cylinder Sets > List > Pick'n'Choose Surface > Primitive > Cone Maths > Operators > Gate And Sets > Strings > String Split With Python you can trim brep with plane , this is a simple code work with single plane cutter. It is a geometry type that represents the surface of an object with a set of Rhino's BooleanSplit command does great job when it comes to splitting solids with surfaces and/or other solids. Hi!

This system consists of 4 panels with a wavy surface. Case 2: Deconstruct Brep. arten February 1, 2019, 3:19pm 9. 10 re2. If this surface has kinks you can turn it into a Brep plane split component. Find coordinates in x-direction. Hello Guys, I have created a bridge using the loft component and now I am trying to split solid into equal elements, but for now unsuccessfully (attachment 1 - blue) I also added a grey bridge which was created using polybeam component, but in this way I am attempting to create a trimmed surface patch with a planar boundary, but when I use the Plane-Brep Intersection curve to trim the Brep, it deviates from the plane substantially so that I cannot perform a radial sort of points along its edge. I have consulted RhinoCommon SDk and it explains that there is a split command for Brep's, but after an hour of trying every possible combination of verbage, i am unable to locate the proper syntax. ) Define your Plane. The grasshopper 'split brep' component works well for splitting one brep into two pieces using a second cutting brep, but I would like to split large breps into smaller ones with several cutting breps. Our fabricated model should stand without wobbling and therefore we will trim everything underneath a ground plane. morteza (Ammari Morteza) June 5, 2021, 7:34pm 5.

Hello @ForestOwl. See photo attached, plan view of geometry C. The curve is invalid. you need the python for grasshopper plugin, First, make a box in Rhino for the overall form. The SubBreps are there to be manufactured as individual panels from glassbut they may want to add mullions so technically speaking I will be If a surface has at least one edge that is bounded on both sides, then it falls "inside" of your desired boundary. if nothing helps: pro solutions: map your surfaces and curves in one base plane, use surface from boundary, copy resulting trim into your 3dspace curves. I think there is a component for random orientation in Pufferfish and Heteroptera I use a trick with a Populate Brep plane split component. 2. 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. Brep plane split component. After creating the structure, I tried to place it on a 2D plane for laser cutting. In the context of Rhino and Grasshopper, you can think of a Brep as the same as a ‘ Polysurface ‘. – Dale. 0007. 6 KB. Code: Watch on. Hello, everyone. Optional curves to unroll with the polysurface (Brep) or surface, curves should lay exactly on the polysurface (Brep) faces or surface. S. Split one brep with another. But I am not sure which part of my script is wrong. For dimensions, approximately 1000 x 1000 x 500 will do. Next we’ll use the Project component (make sure to pick the one that says: “Project a curve onto a brep”), as well as a Z-Unit vector to project the circles vertically onto our base surface. you need the python for grasshopper plugin, If you input a brep you get the split pieces as individual brep's for you to edit. True if the plane trimmed the surface (or polysurface (Brep)), False if the plane did not trim the surface (or polysurface (Brep)) Boolean. I'm now starting to learn Grasshopper and already encounter my first problems. Doubly curve radial waffle brep|brep intersection issue - #6 by martynjhogg My brep | plane isn’t producing the correct results and when it does, One option would be to split the wall with the roof plane (Case A). See attached file. I have searched all the possible preset commands: split, trim, boolean intersect, etc, but have not been able to come across one that would do the job. Splits brep faces by projecting input curves onto the brep and splitting the brep faces. Apply the same principles to your problem. RhinoCutUpSurface as it will work with curves. In this case, for example, i have 3 breps and each brep has to be splitted by 4 planes I do not know why but I split a caped loft surface and used a Brep component to split and the ground plane as the cutting object. Grasshopper RH8-1. What you need to do is create an actual plane (a surface), then convert that to a Brep and use the Split method with this cutting Brep. arnozhangdyd (Arnozhangdyd) March 4, 2019, 1:16am 1. 8 MB) Share.

Added by Parametric House on Grasshopper Commands - Brep/Plane. The effort to create a “solid” from the roadways (bottom right) still fails though, due to an invalid brep result from Brep Join. Resulting untrimmed single unsplit rail revolved surface When you bake this surface into Rhino it will become a usual polysurface (Brep) which is split at its kinks if it has kinks, unless you first run the command CreaseSplitting in Rhino's command line and turn it off by switching it to No. m. Seeing as it looks like you;re making a building, this wouldn’t be desirable. made itthx manuel! stupid question thx for the answer! I wasn't tring with solid difference that was the point EDIT: You are using the Brep | Plane (Sec) component. Brep|Brep would have been good (your surfaces are "also" breps) Ore even better (lighter process) Brep|Plane intersection. png1833×537 89. I need this type of operation for the project I am working on so other methods without a plane are of interest to me as well. Split curves on the outside of the trimming Breps. gh.

T. you need the python for grasshopper plugin, Brep plane split component *** UPDATE 07/2016 *** Now with capped sides after splitting (if applicable) Nothing more, nothing less: Brep + some planes = individual brep pieces. Obviously the componant can handle a multiple curve object as input so this might be more efficient in terms of GH window real estate. 5. Unsplit. followed by >5 more trimming operations from curves in all three planes. --David Rutten there is no method for splitting a Brep with a Plane. If you want to instersect 2 surfaces, use Plane | Plane (PPX) component. I tried to place the structure in a plane using a brep plane before using orients, but it says data conversion failed. 「Deconstruct Brep コンポーネント」を Brep plane split component. Inputs; Brep (B) Brep to split: Cutter (C) Cutting shape: Outputs; Result (R) Not really trying to thicken the brep. In Grasshopper, you can either use the Mesh Split component to split both meshes with each other and join these into closed (mesh) volumes or you can use Mesh Intersection to get the part that is common. It’s better if you share your file and the planes intersect with all faces. ra_mull (Ryan) October 23, 2018, 12:25am 2. Basically from the voronoi 3d I get some polysurfaces, then after a procedure of scaling faces and volumes,I create a mesh and a Catmull-Clark subd;from that point I found the intersections between this mesh( converted into a brep) and the inital So I’m trying to split an untrimmed surface with a plane, I created a Plane Srf and use it on the Split Brep. Is there anything more stable to Split/Trim a surface with a plane? I tried in python but didn’t had much luck Grasshopper プログラムの解説. windows, split, rhino6, brep. It would be better to take the attachment if you intend to take it to Zbrush anyway. The split Use the ‘Join Curves’ component to join the edges to closed curves. It's very long to have a result, my 3dm is very large. The Brep split at lines. lapinski93 (M Lapinski93) April 22, 2019, 9:56pm 1. List of curves that were projected and extended on the Brep. 4 KB. 1 Like. The idea is that I have to be able to unroll a doubly curved surface/mesh. (3) in the fourth picture, the vertical Splitting solid. 3 SubD(细分). Invalid Brep. gh (107. Will_Wang: off the top of my head you can split that loft into two halves and do the intersection separately. Then i used ‘surface split’ 4 I am trying to trim a set of closed Breps between two Planes. B-reps are a very useful addition to the geometrical arsenal that we have. 0 KB) Screenshot%20 (33)1333×750 488 KB. Please consider disabling your ad-blocker to support this website! 🔑 Split a curve with a Brep. Hi guys, so I’m trying to split a brep into equal sections using the Perp Frames + Brep | plane functions, and for some weird reasons the outcome shows extra sections. I have also tried the Split one brep with a bunch of others. Split Brep. All steps you described works for me. you need the python for grasshopper plugin, The surfaces are split with the help of 4 planes and the Brep plane split component whi Hello, I'm trying to delete surfaces which are on the outside of a box. geodesics. Another option would be to calculate the wall shape by using simple trigonometry (Case B). If that what you want you need to explode the polyline and separate the surfaces In this tutorial, we look at a few ways of spitting and trimming curves and solids in Grasshopper 3d. Resulting breps are indicated with the different colors. Name ID Description Type; mesh: mesh: mesh To Split it! Mesh: cutter: cut: cutter must Meah Or Curve Or Brep: Geometry: cutterplane: pl: plane : Plane: direction: dir Breps or meshes which should be split for texturing: Geometry: Plane: P: Plane to use for grouping faces: Plane: dx: dx: Portion of the plane's x axis that is mapped to texture coordinates [0,1] Domain: dy: dy: Portion of the plane's y axis that is mapped to texture coordinates [0,1] Domain: AngleTol: A That said, there's three reasons why Curve -> Brep conversions might fail: The curve isn't closed. Find the solid intersection of the 2 objects and then subtract (solid boolean difference) the intersections from each of the 2 objects. You can scale parts of it with control + shift + double click. E. ExtendThroughBox method in conjunction with the Brep boundingbox to make sure your cutting plane is big enough. You linked a brep to the curve slot, it wont work. JPG1253×377 29. Found a better way. 1 KB) In this Video tutorial, I will be talking about how you can use Brep/Plane intersection tool to produce geometry. I can select the particular item in the result with ListItem, but what about the Hello, I’m trying to create a rib structure from a doubly curved brep. To find the unique cases in which the surfaces intersect, I am using the [Cross Reference] set at diagonal and culling the surfaces that are coplanar. The output consists of only partially split curves. Trim a curve with multiple Breps. you need the python for grasshopper plugin, And I have a bug with the fact to either extrude the mesh and split it with the plane surface (my reference level for the project), either making a Brep out ouf 4 meshes and then split it, either intersect the delaunay mesh directly with a plane surface; either (last solution) : intersect a Brep with a delaunay mesh. gh (4. if nothings helps: pragmatic solution: To trim a curve in Grasshopper, we’ll need to follow the same three steps: Determine the intersection point. 上画像が Grasshopper のプログラムとなります。. Geometry as rg tol = 0. you need the python for grasshopper plugin, If you create a closed polysrf (brep), you’ll get a closed intersection curve and the volume intersection can be computed. ) Using your plane, create a PlaneSurface. I’m using a grashopper to make waffle structures. Figure 4: Referencing brep in Grasshopper Using B-reps. or make sure your surfaces are on the geometry and create a trimmed brep manually. Screenshot%20 (35)1333×750 164 KB. From my limited understanding the split brep multiple Rhino's BooleanSplit command does great job when it comes to splitting solids with surfaces and/or other solids. 5 of TT Toolbox for Grasshopper. Another possibility to split a mesh is with a plane. 9 KB) The usual Unroll components produce a result which is wrong. You can see the strange Breps by baking the split- or the move result. Proj Curves. Please consider disabling your ad-blocker to support this website! 🔑 Brep plane split component. I would like to consult you: (1) in the first two figures, it is impossible to cut a brep with a horizontal surface. Any help or suggestions would be greatly appreciated! Thanks, Ben You used surface split component. This setup does seem to work great with my first attempt. It should not be too difficult I tried using split brep multiple, however, this just splits all of the breps into surface and not solids. A file I'm working on will not create a closed brep. But that’s brought up a different issue. Align Vertices (AlignVert) Select all brep edges that delineate certain faces: Edges from Directions (EdgesDir) I'm now starting to learn Grasshopper and already encounter my first problems. You can even get all of them to split, but moving the curves is not something I plan to do in my usecase. Let’s assume is any mesh with an assigned thickness. Added by Randolph David Prime Jr on January 22, 2018 at 1:27am. Resulting untrimmed single unsplit sum surface When you bake this surface into Rhino it will become a usual polysurface (Brep) which is split at its kinks if it has kinks, unless you first run the command CreaseSplitting in Rhino's command line and turn it off by switching it to No. Attachments: boolean_multiple_example. 6. The how-to Divide curves is focusing on a segmentation with a regular or pattern Parametrichouse: In this Video tutorial, I will be talking about how you can use “Brep/Plane” intersection tool to produce geometry. you need the python for grasshopper plugin, Outside. Basically, I just want to perform the same as the Surface Split component, which doesn't work with open brep. also you could use a brep like a box or something and then use solid difference. e. 1763×566 97. you need the python for grasshopper plugin, I don't know python at all so I'm wondering if the script can be amended to split a brep with multiple breps instead? seems that a brep input into "pln" is acceptable but the script reads the plane of it instead of the actual extents of the geometry. Much much faster. Attachments: planar_fuse. I have a solid (red in the attached image) which I would like to split into two pieces with an intersecting plane (green in the image). 0007 (Released 2022-Mar-08) Learn More. U. Note that on the “B” tree input, only the first item of each branch is used, and the script stops iterate until the last branch of either of the 2 trees, “B” and “C”, if one is longer, everything past that is ignored. you need the python for grasshopper plugin, Grasshopper Tutorial (Brep/Plane) Watch on. View Videos. i used ‘deconstruct brep’ to sort out the surfaces of the brep and i did it again to sort out the surrounding curve of the dividing surface. My initial idea was to create a box from a rectangle, that can be used as a cutting object. For the split part either use the 2nd thing or as an excersize try ( for solid results) to use 2 times the native component in the red group (swap cutter with brep for the “cap”: meaning that the brep splits the cutter in order to get the “cap” brep) and join the pieces in order to get solids as results. I was wondering if a polysurface could be split with a curve? I have tried the new split surface component but it doesn't seem to work with breps. Is there any way to solve this? I’m sorry for my poor English. 5 KB) Brep plane split component. jpxfneegidzksfhidaxi
