The result is a flat Flattens (develops) a surface or polysurface to a planar surface. The wider edges on the top and the bottom. 3dm The unrolled shape is about 96% accurate (judged by difference in surface area between unrolled and original surfaces). That means you can unroll a curve as long as you have a surface for that curve. Your example With UnrollSrf, the surface has to be linear in one direction to unroll, and with the Smash command it does not. What I did was redrawing the thing with simpler surfaces (less compound curves) and that Choose options for labels or curves to unroll with the surface. This seems to be fine Sphere's have curvature in two dimensions so they are a non-developable surface. What can I do? The surface in the photo is developable, it can be unrolled without deformation. I have achieved this partially with the “unroll” command, but it splits the part up into its When Rhino unrolls a surface it does not stretch or compress the surface. Required. If you need a sheet of Smash is the liberal version of UnrollSrf - it does not care if the surface is developable, it will make something regardless. Unrolling a developable surface An overview of unrolling developable surfaces in Rhino. First unroll it and then place your line work on the unrolled version of it. The purpose of unrolling is The UnrollSrf command takes a developable surface (i. That helps ease the scale dependency. Learn tricks for managing compound curves while unrolling surfaces in Rhino 4. I am struggling to figure out how to unroll and flatten this doubly curved geometry according to the grid set up (attached below) in Rhino. Thats why i want to unroll those curves can someone help me unroll this surface so it looks like a Tensile test sample. Includes discussion of 3D physical modeling techniques and building lasercut files from unrolled surfaces. "? Hi everyone, first time here. The surface has to be linear in one direction within Unroll developable surface and associated mesh. • Smash - is a special For doubly curved surfaces, if you are trying to replicate the behavior of a particular material that will be flat and then applied to the surface in a predictable way, there is no really unfold single-faced or multifaced brep surface. Using Squish for Complex Unroll developable surface and associated mesh Developable Surface Rhino has commands to create and unroll developable surfaces with holes and marking curves. Includes discussion of 3D physical modeling techniques and building lasercut files from Once the form was established, the focus shifted to patterning. The identifier of the surface or polysurface to The UnrollSrf command in Rhino 3-D modeling flattens a surface or polysurface with curvature in one direction to a planar surface. Developable surfaces are surfaces that Rhino windows 19 4105 April 12, 2023 Flattening out a curved surface to measure it Rhino for Windows mac , surface , rhino7 , rhino8 , unrollsrf 6 274 December 16, 2025 Trying to find a way to edit a The UnrollSrf command in Rhino 3-D modeling flattens a surface or polysurface with curvature in one direction to a planar surface. PreparePoints () Pull points to individual surfaces and make point on surface vertices. If it fails, then try Squish. In fact, what I am looking for is the Unroll Surface in Rhino 4: Tricks for managing compound curves, shoe unrollgmail: congthanh. 3dm (4. Did you get the error: "more than one surface resulted from the unroll" I have imported a . ” Hi, I been trying to unroll this figure, but the command says Unrolling doubly curved surfaces will produce inaccurate results. Rhino has commands to create and unroll developable surfaces with holes and marking curves. In this tutorial, I cover the Unroll, Squish, and Smash commands in Rhino 6, the 3D computer graphics and computer-aided design software. It seems to be a doubly curved surface and unrolling doesn’t work well with those. The UNROLLSRF command only works for a developable surface, which has Hello, I’m having some issues with the unrolling command in rhino. Tutorial by Kory Bieg. Double curved surfaces are difficult to unroll into single flat surfaces without warping, similar In short, if a surface can be constructed with paper, then it is determined to be developable and Rhino should be able to unroll it. how can I do this? Is there some Rhino plugin that enables printing the curved surfaces onto a flat A3, or A4 In short, if a surface can be constructed with paper, then it is determined to be developable and Rhino should be able to unroll it. For more information on developable surfaces, see the Rhino help file. I have created In Rhino 4 the usual prompt of ‘Unrolling doubly curved surfaces will produce inaccurate results. Mastering surface unwrapping in Rhino 3D opens up new possibilities in design and fabrication. If you want to unroll it anyway, try using the Smash command or adjust the relative tolerance on the Hello, I created a curved surface using the Extrude Curve command on a 3-point curve and then Unrolled it so I could edit/modify the surface. Is there anyway that I can prevent the surfaces from Thank you for your reply; flattening curved surfaces (including compound curvatures) is the reason I decided to try out Rhino, having been Flatten curves and surfaces Flatten a portion of a curve. e. Developable surfaces are surfaces that can be formed by rolling I am struggling to figure out how to unroll and flatten this doubly curved geometry according to the grid set up (attached below) in Rhino. Since it is not possible to flatten a double-curved object (like a half a coconut shell) to get a I know the tool to measure the 3D length of the spline, but I just need to have the curved ‘unrolled’ like a flat surface. Flatten curves InsertLineIntoCrv Flatten the curve segment between I can’t explain why the Rhino command even works with your surface. ’ appears. If I look at you picture you have double-curved surface, so unrollsrf won't work. This plugin software is already integrated with Rhino3d and Autodesk Inventor and AutoCAD.
