IModelJson.BoxProps Interface

Interface for Box (or frustum with all rectangular sections parallel to primary xy section).

  • Orientation may be given in any AxesProps way (yawPitchRollAngles, xyVectors, zxVectors).
  • If topX or topY are omitted, each defaults to its baseX or baseY peer.
  • If topOrigin is given, height is unused.
  • If topOrigin is omitted and height is given, topOrigin is computed along the z axis at distance height.
  • If both topOrigin and height are omitted, height defaults to baseX, and topOrigin is computed as above.
