  1. Begin with a new or existing Rhinoceros model.
  2. For this command, you will need a set of polylines/curves that enclose a shape of the surface you want to create. You can create these lines using any method. (See Rhinoceros 5.5 [polyline] for instructions on working with the polyline tool)
  3. Select these surrounding lines and choose Surface>Patch (type “patch” into the command line).
  4. The Patch Surface Options dialog box will appear with a variety of options. Click “Ok” when done.
    • Sample Point Spacing: This allows you to change the distance between points sampled from the selected curve when Rhino creates the patched surface.
    • Surface U Spans: This allows you to change the number of default U Spans (divisions) for the surface you are creating.
    • Surface V Spans: This allows you to change the number of default V Spans (divisions) for the surface you are creating.
    • Stiffness: This allows you to change the stiffness of the surface being generated through the sampled points along each curve. Low numbers result in loose, flexible surfaces. High numbers result in stiff, rectilinear surfaces.
    • Adjust Tangency: If this box is checked, Rhino will match the new surface to the tangency of the curves defining the edge of the old surfaces. (Leave checked by default for most operations)
    • Automatic Trim: This allows Rhino to find a curve outside of the surface created and trim the surface to that curve. (Leave checked by default for most operations) [premium content]

  1. I created an open curve topology. 15 curves to create a slope. Using patch I get a surface w/o thickness. I can’t figure out give the patch thickness or how to create the footprint into the patch for the model’s foundation. There is a you tube tutorial on how to do this but the crucial instruction is marred by crappy sound and obscured command line. Any tutorials on this to be found here?

  2. Once you have your topography modeled, you should use the project (Rhino 5.13 [project]) command to get a curve that is the footprint of your building that follows along with the contours (topography) you created. I will look for a section of video (lecture) that explains it. Also, I did get your email, just haven’t had a chance to respond yet. Usually email is faster, but I just saw this comment.
