Description

The Curves GordonSurface creates a surface that skins a network of curves. This tool is part of the external workbench called Curves.

Usage

  1. A Gordon surface requires a network of lines or curves that create a support network for the surface.
    • The surface will be "tented" between and over these lines.
  2. In the example above the blue lines (or ribs) represent the shape of the surface at different points along surface.
    • These can be thought of as cross sections along the surface. Or, like supports that the surface will "tent" over.
  3. The yellow lines represent the extent and shape of the surface between the cross sections ("ribs") defined by the blue lines.
  4. These lines (blue & yellow) can be created in sketches.
    • The sketches containing the blue ribs would typically have a placement offset.
      • Each "rib" is in a separate sketch.
    • The sketches containing the extent/shape (yellow) lines will typically reference external geometry from the "rib" sketches for accurate positioning.
  5. These need to be created before the next step.
  6. Switch to the Curves workbench (install from Addon Manager is necessary, if not previously installed)
  7. Now select all the lines of that will define the surface.
  8. The order of selection defines the stitching or tenting order.
  9. Use multi-select to select all lines defining the surface. (Left click while holding the Ctrl key.)
  10. Select the ribs first, in order. (In the example above, select the blue lines from left to right. or right to left.)
  11. Continue to hold the Ctrl key and select the extent lines. (Yellow lines in the example above.)
  12. Invoke the Curves GordonSurface command several ways
    • Press the button
    • Use the Curves → Gordon surface

Properties

  • DataPlacement: Can be used to adjust the placement of the resulting Gordon surfaceSee: Placement
    • Note: The Placement properties do not adjust the placement of the curves/lines used to create the surface, only the surface.
  • DataLabel: User specified label (name) for the surface. (Default: Gordon)
  • DataOutput: Defines the output type. (Default: Surface, Options: Surface, Wireframe)
  • DataGordon>Max Ctrl Pts: (Default: 80)
  • DataGordon>Sources: User selected lines that are used to create the Gordon surface.
  • DataGordon>Tol3D: 3D tolerance (Default: 0.01)
  • DataWireframe>Samples U: Number of samples in the U direction. (Default: 16)
  • DataWireframe>Samples V: Number of samples in the V direction. (Default: 16)
