Rhino planar surface not working. YNBA (YNBA) January 14, 2019, 2:53pm 3.

Rhino planar surface not working And the outliner shows planar trimmed surface. 2_Sometimes it helps to join the curves first. You may need to join all your surfaces into a BRep first. 5 KB) I see this does not work on interior corners I’m a novice Rhino user, so given the technical skill of your design- I’m not sure this will apply to you. I need it working for Grasshopper. After usingsetpt command with checked z direction the bubble for rhino shows the curve is planar and calculates the area. Rhino. I understand that it’s relevant to precision but why rhino doesn’t handle this correct to the level of the document precision. I have created two straight curves and an arc and joined them together to . Oddly, this is not the case when exporting Rhino surfaces as DWG and importing the DWG into Sketchup. And the naked edges don’t help either. the first plane which was on the top worked fine but the bottom one doesn’t work. EDIT: In place of array hole, make the holes by extruding the planar curve into a cylinder that passes right through the ring, polar array it about the ring centre to make a second cylinder and boolean The problem is the bounding box of the reference surface is different to the shape of the surface. jpg 931×698 472 KB after that i made only 1 surface but it don,t work. Your curve not be planar (select the curve and type projecttocplane > delete input > yes you can use The openings did not have closed, planar loops of edges. Rhino for Windows. The point was to make a grid on a lofted surface in Rhino in a way that would create planar cells on the non-planar surface. Then, you can make a surface over those 4 points. One of the characteristics of NetworkSrf is that it does not care much about the curve structure like some surfacing tools - it refits all the inputs behind the scenes to make the surface. 3dm (1. If there is no scale handle, then the curve is indeed planar. The surface exists, but it is invisible. i am This is in case the adjacent rooms to the corridor are not exactly along the same straight plane. Make a note; this is important. I’m working on my PC right now and It doesnt Then, use ruled surface to connect them together (maybe some grafting or flattening needs to happen at this time). I used this method successfully on virtually the same topography two days ago, but now it no longer works on the original topography nor on any new topography; it only returns a flat surface. quite sure this will cause some work for support and teachers. Why I cant planar the closed curves? I click planar with output as polygons but nothing happens. 3 KB) Hi, here is a little problem I encounter everyday- unable to do cap actually I am careful enough to the edges that I am going to do cap/ planar surface, but I always stuck here Assuming both options didn’t work make a vertical surface that fully cuts through the object move it into the object like a 1/4” just enough to clearly cut some off, split the extra off take the now fully planar side do the dupedge join then Let’s say I have a bunch of co-planar surfaces/trimmed surface that can be joined together, how do I merge all of them into one trimmed surface without interior edges? For example, lets say I have a bunch of square surfaces laid out in a grid, how do I turn them into one large square with no edges in the middle of it. Just instead of the straight line of a cube the line is roughly a third circle and the box is twisted into a crescent shape. 3dm (190. Hi, I want to trim this object by the plane so that I have a flat surface. Dim arrObjects. 5 KB) Transforms non-planar curves into planar cuves parallel to the world XY plane and at the choice of maximum or minimum Z Hello, I made a lettering with the cv curve. 8 KB) When you loft your curves with style “Straight Sections” and unroll the surface the area is 0. So joined curves should be just fine. Probably the fastest way to get what you are describing would be to cap what you have, explode the solid, then rebuild the top and bottom increasing the UV counts, Go to rhino r/rhino. Non-Planar Curves: If the curves are not planar, the tool will not work as When I try to split the planar surface in half using command split planar face, it doesn’t leave me a curve in the middle, and therefore I can´t edit the edge I made. gh (23. Should have yourself a make shift cap to close it up. rhp (33. I’m trying to create a Planar “Surface” which is called Planar Curves under the Surface dropdown menu. Either: 1) the curve being used isn't closed, or 2) it isn't really planar. for UnrollSrf to work here you have to use the dashed version (-UnrollSrf) to adjust the tolerance, in v7 that was not necessary if i remember correct, but whatever. i tested the UnrollSrfUV but in the mode “natural” its not working Here’s a simple example of including planarity during the initial shaping process: pre-rationalize_planar. I’ve drawn a closed curve and used “PlanarSrf” to create a planar surface. you can force it planar by clicking the scale handle and entering 0 in the scale dialog box then enter, the curve will scale to 0 and be planar. Rhino 5 create solid from planar curves issue. First, try to duplicate the borders of the hole you want to close by using ''dupborder'' or ''dupedge'' commands. Easier to modify all parameters including thickness (Offset ‘D’ input) and the results are According to Bubble for Rhino the curve is not planar. 3_Since it looks like you're creating extrusions you could also try [Cap]. ” Cap Planar Holes Not working properly in Mac Wenatchee Hi, stages are simple, create cylinder with sloping top, use sweep2 for slope, then fillet the edges. The bounding box is rectangular, & the surface isn’t, but the curved surface is divided equally by rectangles so it’s not mapping properly. The issue I have is that I do not see a way to create one surface for every face in the mesh. mac, help, jewelry. AddPlanarSrf arrObjects. If an extrusion of a theoretically closed planar curve doesn't cap, even though you chose Extrude from the solid menu or clicked cap=yes in the command line, there are one of two things wrong. If your curves wont join into a closed planar curve then [Planar Srf] wont work. user2187 December 10, Rhino for Windows. YNBA (YNBA) January 14, 2019, 2:53pm 3. Array hole requires the hole to be in a planar surface, so it isn’t going to work on this ring. Hello - Cap works where there is a closed, planar loop of edge curves. Understanding how to effectively use this tool can significantly enhance your modeling efficiency and precision. CalypsoArt October 12, 2018, 9:09pm 1. 6 KB). Hello Guys, I have a problem with setting Surfaces in Grasshopper and Rhino. What you can do is loft through lines. ryan272727 (ryan “The Cap command fills openings in surfaces or polysurfaces with a planar surface joined to the hole edge. GetObjects("Select planar curves to build surface", rhObjectCurve) If IsArray(arrObjects) Then. but i get holes in it (see picture) first thought: planar trim surface sucks. There is a failreport " intersection curve ends at an open edge ". 3dm (150. AddPlanarSrf (arrObjects) Parameters. Free How to Rhino Community 👉 https://www. Maybe the problem is that I added multiple vertex at every each corner of a letter so that the corners can be sharp enough? You can see a corner on the second screenshot. Could someone come to my aid. However, if anyone else is struggling with a wireframe extrusion that has a closed loop, on a planar surface, and was Go to rhino r/rhino. Nima September 21 one of the surface edges at the join is not really open - it may be doubled back on itself. If the “perfectly touching surfaces” are touching in the sense that they are planar to each other than Join won’t work unless two adjacent edges, one from each surface are within absolute tolerance of It worked before in other models, but this one is challenging. I then booleanSplit the two crossing cylinders into it, Fillet the four edges radiating from centre, so far so good, then unable to How do I define where the seam of Unroll developable surface is? My ultimate goal is to have various features intersecting the extruded surface in the attached picture, then do a trim command to cut the holes in the extruded If both side result in a flat cap, you have closed planar top and bottom. The curve is planar. The purpose of Cap command is if you have a planar hole (or holes) in a surface or a polysurface it will fill the hole(s). The icon shows a bunge of curves and lines which are overlapping at the end. Trying to help in this thread: Polysurface offset - Grasshopper - McNeel Forum If I have this surface in other cad software, I can grab these bottom faces and offset them and the software understands that I want that entire shape extended: How do I do this in Rhino? Offset just pushes those surfaces out straight & I can’t see any offset options to allow this. It will only work when a hole is planar. With NURBS surfaces, that means it’s all about the input curve quality. Hello- In plain Rhino, DupBorder > FilletCorners > PlanarSrf. 1: 519: Completely closed curves but extrusion is hollow. But even Hello- please start a new topic, explain what is not working for you and post a Rhino file with an example, and I’ll try to help; I cannot get much from your comment -Pascal Carlos_Inclan (Carlos Inclan) September 12, 2022, hi, I was wondering which way is the best to check if the set of surface in the model are flatten or not, one quick trick should just to type sel planar srf, so I know those should not be planar, other ways ? 2-so how to i dont need the same structure although it would be nice to control that, anyway the adge “2” and “0” is totaly strait cause of the 1 degree in this direction. 3: 2132: July 22, 2024 Extruding a surface. 0 KB) i hope somwoene help me out greetings Peter. Suggestions? McNeel Forum Cannot cap Loft. Maybe there is also another approach in repairing a curve. @Helvetosaur’s “PlanarizeCurves” script is more like what i want but it should work for selected surface points row and both end points should be fixed. Area is 134. kinda gets you there. I made sure the curve was not intersecting using the _TestCrvSelfIntersection command and it found 0 unable to do planarsrf. This is probably the best option. then PlanarSrf won’t work because a planar surface is flat and two of the edges here are curved. If I select two or more adjacent faces, the surface command creates one surface over all selected faces. What I am trying to get to is to be able to merge Rhino needs to have a closed, planar curve to create a cap surface. By this, you can construct the curves you need to create a surface around the hole. If I could the base curves that i extruded are not planar. skool. Subsequently, the “Patch” command fails to correctly generate the surface based on the red curves. I see many people in videos do it and all of my colleagues can do the exact same thing but for some weird reason I can’t. duplicate nurbs circle, scale down real small, and loft with the edge of cylinder. tigerpix February 12, 2019, 10:13pm 1. I noticed that when it has been called, it asks to select a planar closed curve, but no mention of that has been made in the help file. In this way you can use the edges of the four surfaces as starting curves so you can obtain better surf continuity. After you have that, you can trim that surface with your original object. arrObjects = Rhino. I have the lines outlining each contour, so I just need to make these into surfaces and extrude them to have my 3D map, in theory. The same happens many times when I intersect planar surfaces with curved surfaces. I’m not sure what data you’re starting with and what the workflow is but I bet there are Hello, I have been trying to split this model into two halves in Rhino based on Voronoi boundary information. However, the resulting surface doesn’t perfectly align with the curve, and I can see noticeable gaps between them. ok, adding another loft at the end. Solid > Extrude. Cap does not work because the openings are not planar. Syntax. If you want to do it the other way round, making a surface, then turning it into a planar quad mesh, some of them are open curves but when i run the closecrv command, it just connects them randomly and not according to the shape/boundary. I’ve tried to extrude the text inwards, and then using a boolean difference to subtract the letter from the model. The only thing that has happened to “Smoothing U” did a better job but not perfect as at green surface. 0624 sq millimeters (7. you can more reliably Hello, I am trying to roll a planar surface along a curved developable surface as though it’s a development but it isn’t working properly. Kaamil_Hasan_Dahodwa (Kaamil Hasan Your object is not bad, just open. Trace the 5-sided curve you already have. windows. i tried to close one side of a loft cylinder. If the holes in your extrusion is not planar, then the ''cap'' command would not work. py (1. (within doc-tolerance) coplanar surfaces often cause Booleans to fail ok just do the following: It's not working because your polyline is not planar. However, selecting the segments very frequently gives the Non-planar surface warning. If that doesn't work, your boundary is ill-defined or your curves aren't planar. End If. image 993×625 15. Additionally, you have projected a curve to a surface but there is no "link" between the two. Example. This actually sort of worked, except that I The red curve was generated with the “curve from two views” command. Does anyone have any idea on wh Hi,there I created several curves by coding,but when I use _planarsrf to create surface,I can’t work. How to know Hello everyone, I’m experiencing an issue with the “PlanarSrf” command in Rhino. forma a sella. I lol I thought I had already edited the last post!. Use Hi all, I am trying to use the Drape command to create a topographic surface in Rhino 5, by draping over a stack of extruded, closed contours. Perhaps this script might help then: PlanarizeCurvesMinMaxZ. This plug-in includes a FilletSrfCorner command - FilletNonPlanar. 2 KB) (with the “Loft” So an easy fix to "reset" the UVW for any surface is to highlight it, silhouette it, join those edges, use planar surface command to make a new surface from the perimeter, then delete the edge curve. It looks as if it is stuck in wire image, (when all other layers render, shadow, Rhino needs to have a closed, planar curve to create a cap surface. I’m pretty new to Rhino and am having trouble creating planar curves/surfaces so I can create UV surfaces, etc. If an extrusion of a theoretically closed planar curve doesn't cap, even though you chose Extrude from the Neither edge of that disk is planar, so the planar srf command will not work. I have the tolerance set to 1/128. While drawing like this, I should be It looks like the MakeHole command is not working properly on open surfaces. Is there a trick to activate this function? I’m trying to create a topographic map for a class. Hi there, I am trying to create a surface using the PlanarSrf command. and thus a PlanarSrf command Even when surfaces in Rhino are 100% planar, the Sketchup exporter splits them. As sometimes the curve would work making a planar Go to rhino r/rhino. This surface should have it's UVW settings mapped accurately and then knowing that you can at least fiddle with the values and figure those out In this tutorial we are going to talk about how to deal with such problems and introduce many different ways of dealing with them using simple rhinoceros commands Here are a few commands and approaches to cap a non-plannar edge: 1. I have a quadrilateral about 28 ft x 8 ft that the plans think is planar but Rhino does not (planarsrf). I couldn’t create a surface off this with Patch or Loft, and using EdgeSrf after splitting the curve doesn’t work either. Why I have no clue. Hello- the faces not merged are not coplanar, in fact not planar at all, Split surface not working. And this stripe is coplanar to the lower surfaces of the upper part. Of course they need to be planar, but in GH it does not work with overlapping curves. IMO your selection line width looks like it is a surface already If this is not the case try using PlanarSrf for one closed loop of curves at a time. you can use gumball as a quick “planar check” if you see a scale handle in the z, then the curve is not planar. and you should have a final working result. Hello, I have a joined closed curve made up of non-planar curves. NetworkSrf command seems to need curves that are continuous, and not joined curves. You can even use the O It's not working because your polyline is not planar. (As broad as Rhino’s meshing tools run, it’s likely I’m missing a trick here. McNeel Forum Planar surface don,t work? Rhino. The bottom curve is not planar. split. Doing the whole shape with GH is WAY BETTER, without a doubt. It is equivalent to running DupBorder and then making a planar surface and then joining. Select it and try _PlanarSrf: Since it is not planar there can be no cap. Cap does not work to close it, neither does making the curves top & bottom into surfaces and trying to join. I even I’m following a video and when he used the surface from planar tool it made the square into a solid surface, but when i do it, it just divides the one large square into 4 Planarsurface not working Rhino. windows, Rhino for Windows. Here’s what you might do: use Using Rhino for Mac, with an dxf 2007 imported from autocad. How to fix "The openings did not have closed, planar loops of edges" issue when trying to cap Help Needed I'm trying to cap this shape but I keep getting If you look at the front view you will see that the curve is not planar. 6 KB Both difference and intersection can only take interactions between two individual surfaces - the The "Surface from Planar Curves" tool in Rhino is a fundamental feature that allows you to create surfaces from one or multiple closed, planar curves. image 1257×1321 156 KB. r/rhino. The result is not always planar I am a little disappointed that the planar surface component doesn´t work like the used icon is promising. If you used a non planar surface to trim them, I would suggest going back to that Rhino for Mac. I’m experiencing an issue with the “PlanarSrf” command in Rhino. com The Rhino surface planar (Brep) Booleans are basically calling these methods in RhinoCommon: image 1459×277 33. You might get confused with the terms because I'm talking common language not really Rhino language. Another note: I am not sure if it is possible to have a PLANAR Surface The loft is fine, but open top and bottom. If it was Rhino only, I would adjust the curve and then form a volume. This community is for professional, student, and hobbyist users of McNeel's Rhinoceros 3d modeling software and the Grasshopper generative modeling plug-in. To get around this, split the surface with the curves, then use ExtrudeSrf instead. Works a treat for non planar shapes, but need to try and work out how to solve more organic fluid shapes. Same applies for imported curves from Illustrator that seem to work as I would delete some corner points for further use. I tried a polysurface which I explode, i am going nuts. Just tried to cap Make sure to run gcon so they are at least tangent to the isocurves of the lateral surface and run a network again. From the same Curve, I am going to extrude this to a thickness of 6mm, but will need Planar If you have a rectangular planar surface under your discs (that they are sitting on) that will be mapped to the curvy surface, and the discs will sit - or rather be draped Dali-style - onto the curvy surface. Then, try surface tools to create the cap for your solid. AddEdgeSrf thought so, rhino often doesn't like non-planar things Cap will only work with planar curves, which doesn't seem to be the case for most of your walls. 1 Like confusing, and it’s been like this If it is something simple like a planar surface, super easy, I often will dupBorder, simplyfyCrv, then planarSrf, and you have a nice, clean result with a clean trim curve. Two things: Your document tolerances might be off relative to the size of the rectangle. windows, rhino5. It should look like the Ive been modelling hat shapes in rhino, that i then unroll surface and silhouette for the pattern to make in real life. image 1185×844 determine the diagonal trim plane you want and create a plane surface there (pink). after that i build the hole thin again but it dont work ??? second floor. Extruding the curve won't result in a solid, because you've not told rhino what shape to make the bottom and top surfaces, as they are not planar. I’ve set my absolute Make a rectangle over the non-planar edges following the same angles and covering the whole structure. i actually got a message, the surface is smaller, you can also adjust the warning in the dashed version. When I tried to extrude two sets of different (joined) curves, it wasn’t working, so I figured that I would t Hello, I am trying to project/flowalongsrf/pull curves on a surface (named good surface on below picture) with minimal deformation (as on “working on this surface”), but I am not able to. so "cylinder" was open, and i tried to close it with planar trim surface. When you get back to the first point, it should be both closed and planar. The first few levels work, but frequently I am working off plans that are using 1/32" of an inch generally and 1/64" sometimes. com Its kinda stupid that they put it in the Solids menu because it will never work on a solid. 2 MB) McNeel Forum Unable to cap. Here’s what I’ve checked so far: The curve is closed and seems planar. leaves me with a bunch of points with Z-value 0, lying flat on the "ground". There are other surface commands that can do the job. 45% bigger after unrolling. Very nice, thanks. fill the hole using a simple primitive rhino polysurface and weld them using boolean union command 2. Const rhObjectCurve = 4. see attached images. If it is a more complex surface, like with many other things, it’s garbage in, garbage out. 3dm (38. However, the resulting surface Free How to Rhino Community 👉 https://www. ExtractSrf the “notch” surfaces For 3D printing. Pascal, I am working in Is there a command to rebuild a curve and repair geometry? As you see the curve creates no proper results during pipe command. I am trying to project these lines onto a surface however as can be seen in the photos it Rhino offset sucks, most offsets suck. I know they should be closed planar curves,and I checked they were closed curve,my question are : 1. until i seen a close up render i got again Hi Per, Please take a look at this file: example-loft. One closed curve will not planarsrf. Also See. I happen to be using Gemvision Matrix but I think my problem is a very basic Rhino or Rhino settings problem. hmcneil1 September 28, 2014, 6:49pm 1. 1: The idea was to "cut" all cylinders with this surface (boolean difference) but it doesn't work because of the pyramid-geometry around all cylinders. And you need to flip your polysurface after fixing the issues before you cap. wow works. 1 Like. Projecting the curves onto the surface have also made them non-planar. com/howtorhinoHow to use Planar Surface in RhinoRhino tutorials for architectshttps://howtorhino. Some of these clearly do not have then, a couple do but are coincident at the centers of the shapes so Cap cannot close the object - you can Can anyone explain why (many times not always) when I extract border curves from planar surface’s the result is not a planar curve. Apologies if I have misinterpreted your sketch. Is there any way to manually close the curve in a way i I have also seen a thread on this forum about Rhino 8 WIP and isocurves turned off by default for planar surfaces. If I dive there is a small planar stripe in the smaller / lower part. ” What is the problem/error? nO_CAP. Whenever I have a surface in Grasshopper and right-click “Set one Surface”, it won’t let me select my surfaces in Rhino. You can use EdgeSrf, Loft (between the curves), ExtrudeCrv, Sweep1 or Sweep2. Here is your deffinition with a little mod. I’m trying to add the male part of the puzzle piece to the unrolled surface at the bottom of the top view, but can’t get the unrolled surface to split: "Split failed, objects may not intersect or intersections may not split object" I’ve tried projecting the curve onto the surface, aligning This might be the best thing to look at changing if possible to accommodate the end goal of a single trimmed and planar surface. 3 KB. I am trying to project these lines onto a surface however as can be seen in the photos it doesn’t seem to want to do so! Project onto s not working for me. 20190418_115140. 86 % ) smaller after unrolling Creates one or more surfaces from planar curves. zetj hlci frgnkq xistf kpsvck mme tld ysxa xxhx upwqm dlh txibzz ktdaa swtdzou jke
