UMinValue Property (ICurveParamData)

Gets the minimum U parameter value.

.NET Syntax

Visual Basic (Declaration) 
ReadOnly Property UMinValue As Double
Visual Basic (Usage) 
Dim instance As ICurveParamData
Dim value As Double
 
value = instance.UMinValue
C# 
double UMinValue {get;}
C++/CLI 
property double UMinValue {
   double get();
}

Return Value

Minimum U parameter value

Example

Remarks

The minimum U parameter must always be smaller than the maximum U parameter. If the curve and edge are in opposite directions (ICurveParamData::Sense returns false), then the minimum and maximum U parameters are in negative parameter space.

For example, if the minimum U parameter is 10, and the maximum U parameter is 5, then UMinValue = -10 and ICurveParamData::UMaxValue= -5.

To normalize the values in positive parameter space, swap the two U parameter values and then negate them, so that the value of the minimum U parameter is 5, and the maximum U parameter is 10.

If the curve is closed and the curve starts and ends at the same point, then UMinValue and ICurveParamData::UMaxValue are a period apart.
