IModelJson.ConeProps Interface

Interface for a Cone, defined by two centers and radii.

  • A Cone typically has circular sections perpendicular to the axis line between centers.
  • The cross section xy-plane is specified by an AxesProps:
    • Typically this is an xyVectors.
    • Elliptical cross sections can be specified with xyzVectors, which admits skew vectors and/or vectors of different lengths. Elliptical cross sections are scaled by radius.
