Specifies the parameter from which the Length needs to be measured.
Specifies the length of the curve to be measured from the FromParam argument in the logical flow direction of the curve.
Returns the computed parameter.
Description
Returns a parameter at a given length, measured along the curve, starting from a given parameter.
Syntax
Visual Basic
Public Sub GetParamAtLength( _
ByVal FromParam As Double, _
ByVal Length As Double, _
ByRef Param As Double _
)
Parameters
FromParam
Specifies the parameter from which the Length needs to be measured.
Length
Specifies the length of the curve to be measured from the FromParam argument in the logical flow direction of the curve.
Param
Returns the computed parameter.
Remarks
The direction of measurement is always in the direction of the logical flow of the curve. If no inherent logical flow can be assigned (as in the case of an Edge shared by two Faces), the direction is the direction of increasing parameterization. If the input starting parameter is out of the bounds of the curve's parametric range, the function snaps the value to the closest endpoint, before computing the parameter. If the length being measured exceeds the bounds of the curve, the endpoint parameter is returned.
