Methods


o Sub GetChoiceNo( val1,
val2,
val3,
val4,
val5)
Returns a sequence which identifies a solution among all possibilities.
  • val1 = Solution number (from 1 to n).
  • val2 = oOriTgt1

    • This orientation allows to compute just the results that are tangent to a specific region of the first curve.
    It can take 3 values:
    • +1 : the result has the same orientation as the curve,
    • -1 : the result has the opposite orientation of the curve,
    • 0 : no orientation is specified.
  • val3 = oOriCvt1

    • This orientation allows to compute just the results that are tangent to a specific side of the first curve.
    It can take 3 values:
    • +1 : curvature direction of curve and cross product of support normal and result direction are in the same direction,
    • -1 : curvature direction of curve and cross product of support normal and result direction are in opposite directions,
    • 0 : no orientation is specified.
  • val4 = oOriTgt2

    • In case of curve/curve bitangent line, this orientation allows to compute just the results that are tangent to a specific region of the second curve .
    It can take 3 values:
    • +1 : the result has the same orientation as the curve,
    • -1 : the result has the opposite orientation of the curve,
    • 0 : no orientation is specified.
  • val5 = oOriCvt2

    • In case of curve/curve bitangent line this orientation allows to compute just the results that are tangent to a specific side of the second curve.
    It can take 3 values:
    • +1 : curvature direction of curve and cross product of support normal and result direction are in the same direction,
    • -1 : curvature direction of curve and cross product of support normal and result direction are in opposite directions,
    • 0 : no orientation is specified.
    Example:
    This example retrieves in vakl1,val2,val3,val4,val5 parameters for solutions for the LineBiTangent hybrid shape feature.
