It’s a very small script: import rhinoscriptsyntax as rs import scriptcontext as sc import Rhino def ToggleObjIsocurves (): msg="Select surface or polysurface objects to toggle isocurves" obj_ids=rs. 811K An isoparametric curve (or isocurve) is a curve of constant u- or v-value on a surface. the command is now ExtractCenterline - it should work on any surface that has a constant curvature in one direction, like a pipe, (including cylinders, torii and spheres -returns a point in that case) as well as cones. Always display objects as bounding boxes. If the surface is a single knot-span surface like a simple rectangular plane, Maybe for this particular scenario MergeAllFaces could work, but I really miss the ability to select entities, edges, and be able to hide them just for presentational purposes. 2m 18s. Shade vertex colors. (The first image below shows the isocurves all leaning and the Shades with isocurves not obscured by objects in front. Would appreciate some help! Thank you 🙂 This is similar to the post here where there was a discussion of how to create renders or vector images of surfaces. The Raytraced display mode sets the viewport to a rendered mode with Cycles, a real-time raytracer. Rhino Rhino for Windows. Change objects to bounding boxes only when zooming or panning. This feature would save a lot of workarounds to get clean presentations. I rotated the model with my 3D mouse and they disappeared. Withing Rhino lingo I interpret Isocurves as indicating lines on NURBS surfaces running in U and V directions, so I wonder what do you mean by them as 3DS and OBj formats only export meshes.
