Facet Curve

Used to convert curved elements and B-spline curves to lines, a line string, a stream curve, arcs, or points.

You can access this toolbar from the following:

  • Ribbon: Modeling > Curves > Curve Utilities > Flatten/Facet > Facet
  • Toolbox: Curve Utilities


SettingDescription
Method Sets how the dropped element is constructed.
  • Equal Arc Length — The B-spline curve is evaluated evenly along the arc. Each segment has the same arc length, as defined by the value for Number.
  • Equal Chord Length — The B-spline curve is evaluated at a given number of points such that the distance between each successive point is the same.
  • Fixed Chord Length — The distance between each pair of successive points evaluated is the same as the chord length.
  • Max. Chord Height — The maximum chord height for all of the line segments is less than the Chord Height.
  • Equal Parameter Length — The B-spline curve is evaluated evenly in the parameter space by the Number value.
Facet To Sets the element type to which the selected B-spline curve is converted.
  • Line String — The B-spline curve is dropped to a line string.
  • Lines — The B-spline curve is dropped to a number of connected lines.
  • Stream Curve — The B-spline curve is dropped to a stream curve.
  • Arcs — The B-spline curve is dropped to a number of connected arcs.
  • Points — The B-spline curve is dropped to a number of points.
Number Sets the:
  • Number of points when Method is set to Equal Parametric Length.
  • Arc length when Method is set to Equal Arc Length.
Keep Original If on, the original B-spline curve is retained.
