Pick a point on the curve. I am trying to make a solid by non-planar curves. When I create what should be a flat, planar surface, I see that there are red lines and that I cannot select the surface. If a curve is wholly within another curve then it will be treated as a hole boundary. The waterjet guys don’t want surfaces; they want simple curves. The Box, Cylinder, Tube, ExtrudeCrv, and ExtrudeSrf commands create extrusion objects. py (1. longer but gave me a pretty surface: duplicate borders on the ribbon to get top and bottom curves, then place two planes intersecting the ribbon, and use them to "split" the curves into four open segments each. If you want to select and isolate all non planar curves, you can run this macro: _SelCrv _Isolate _SelPlanarCrv _Hide. Then I did CurveBoolean, selecting a few curves at a time, locking the resulting curves before CurveBoolean the next batch. in top view), allowing you to set the correct elevation in one of the other viewports (eg. We make boat decking and use a 3D scanner. If the contour curves are in 3D, Array the border curve in Z by the contour increment so there is a border at every level and then proceed level by level with CurveBoolean. What’s the best way to “explode” all of the selected surfaces into their edge curves? From searches of the Forums, as well as Google, it appears not to have a simple explanation. At the moment, I have the Voronoi pattern mapped onto a surface already, but since the surface isn’t flat, it is creating non-planar Voronoi cells. The falloff distance is adjustable, allowing the changes made to the curve to be more or less local. However with this object I have edited the curves so they no longer match the base object so cannot use this method Sep 2, 2013 · If the topo curves are flat in 2D, use CurveBoolean with the outline curve and the contour line curve (do not delete the input) to create a closed region. Using the patch command on the projected curve gives strange results. Anyone knows? -C-H-A-R-L-E-S- 6 - Create Surfaces from Curves. Desired angle is 30.

I need to get the boundary curves of those hatches. Use EdgeSrf to create a surface using the four segments. But I have to reconstruct everything with planar surfaces to get the final sofa sculpture production ready. Sweep2rails is not working in this case, because I can only choose the way the sweep begins and not how it ends. As you can imagine, most boats have multiple levels (steps) and angles (ie, angled footrests). Important - the resulting surface will have singularities at the ends of the curve segments which can cause problems in other operations. Resource Type Script (VB Script) Jan 22, 2016 · hey guys, i am searching for a way to get a trimmed surface from a closed planar polycurve (in my case a polygon, only straight edges). All surface creation commands in Rhino result in the same object: a NURBS surface. Helvetosaur October 3, 2023, Oct 4, 2019 · Any two circles, co planar, randomly placed and sized. Once the boat is meshed we use Rhino to develop fairly simple, mostly planar curves in the shape of the decking we want to CNC.

The first is the curves that can be made into surfaces, and these are marked with red groups. I just want to draw a line that is tangent to both… I tried starting with the tangent snap option, but that get’s nothing. Up until now I've been using PlanarSrf to make surfaces from curves drawn one one plane, but now I have a shape that slightly bends into another axis so that doesn't work anymore. Instagram: https://www. 4. Notes If the curves partially overlap, each curve produces a separate surface. The NURBS form can represent simple shapes, such as planes and cylinders, as well as free-form, sculptured surfaces. Perhaps someone will take the time to answer my very basic question, thanks!
