In the attached image you see a simple shape. A common way of working in 3-D is to draw curves that represent edges, profiles, cross-sections, or other surface features and then to use surfacing commands Important is that the number is odd, so you get a layer of control points right along the middle. If its a planar surface that’s not parallel to a principle plane, you will need to I’ve extended my guidelines past the intersection points, found the surface corners from this, created the surfaces and now wondering how to make the surface blend from these - 1) Create a grid .

So my understanding of (poly)surfaces is not great. PART I: SURFACE EDITING. Drape Create a surface through the intersections of objects and points projected toward the construction plane. Thanks ( I attached the file ) Rhino lets you edit curves and surfaces by moving control points and edit points. thank you Mitch, set point is only x,y and z, creating a cplane is time consuming for me. Later on after some more editing I decided to trim the surface into rectangular extents as the edges had become too Urgent Help! I am trying to create a surface from points on rhino/grasshopper. Scale control Create surfaces. Draw a rectangular grid of point objects. What Am I missing. GetObject("Select surface", 8) If IsNull(strSurface) Then Exit Sub arrPoints = Rhino. If I can create a point at the center of each text object, and then create a surface and/or cross-sectional curve to represent those points in 3D space, I can create visualizations of the bottom profile, which is my end goal. I’ve tried boolean commands and filleting the edges, but it hasn’t worked. The I assume you just want the surface (not the isocurves drawn above in the picture). 1. if you’ve set the CPlane inside Rhino, enable Project in the OSNAP palette, then start DigClick or Points command from the 3-D Digitizing toolbar, all Create surfaces.

Surface Generation with Control Hi All, I’m pretty new with grasshopper (this is my first post) and I have an issue with CrvSrf which needs UV points to draw a curve on a surface. The purpose of the point placement is to extract XYZ coordinates at If you hover the mouse cursor over “Plane” input the message box tells you that the surface is loaded as a plane: O(origin point) Z(normal vector). Move the created control points to edit the surface. I have imported the list of points. I started by importing a mesh, extracting points, creating a patch surface, and Change the degree of the polynomial that defines the curve or surface by adding or subtracting control points between knot spans, while maintaining the knot structure. I found a similar function from the RHINO SDK C++, such as: RhinoProjectPointsToBreps() or RhinoProjectPointsToMeshes() .
