ModifyInstance Method (ILocalLinearPatternFeatureData)

Modifies the specified pattern instance with the specified distances in Directions 1 and 2 in this linear component pattern feature.

.NET Syntax

Visual Basic (Declaration) 
Function ModifyInstance( _
   ByVal Instance As System.Integer, _
   ByVal D1Distance As System.Double, _
   ByVal IsD1OffsetFromNominal As System.Boolean, _
   ByVal D2Distance As System.Double, _
   ByVal IsD2OffsetFromNominal As System.Boolean _
) As System.Boolean
Visual Basic (Usage) 
Dim instance As ILocalLinearPatternFeatureData
Dim Instance As System.Integer
Dim D1Distance As System.Double
Dim IsD1OffsetFromNominal As System.Boolean
Dim D2Distance As System.Double
Dim IsD2OffsetFromNominal As System.Boolean
Dim value As System.Boolean
 
value = instance.ModifyInstance(Instance, D1Distance, IsD1OffsetFromNominal, D2Distance, IsD2OffsetFromNominal)
C# 
System.bool ModifyInstance( 
   System.int Instance,
   System.double D1Distance,
   System.bool IsD1OffsetFromNominal,
   System.double D2Distance,
   System.bool IsD2OffsetFromNominal
)
C++/CLI 
System.bool ModifyInstance( 
&   System.int Instance,
&   System.double D1Distance,
&   System.bool IsD1OffsetFromNominal,
&   System.double D2Distance,
&   System.bool IsD2OffsetFromNominal
)

Parameters

Instance
Pattern instance number (see Remarks)
D1Distance
Distance from the pattern seed in Direction 1
IsD1OffsetFromNominal
True if D1Distance is the offset from the nominal position of Instance, false if not
D2Distance
Distance from the pattern seed in Direction 2
IsD2OffsetFromNominal
True if D2Distance is the offset from the nominal position of Instance, false if not

Return Value

True if the pattern instance is modified successfully, false if not

Remarks

To calculate Instance:

  1. Ensure that ILocalLinearPatternFeatureData::D2PatternSeedOnly is set to false.
  2. Calculate:

      For a bi-directional pattern:

           I = n2 * (i - 1) + (j - 1)

      For a uni-directional pattern:

           I = i - 1

      where:

  • I = pattern instance number
  • n2 = number of instances in Direction 2
  • i = index for Direction 1
  • j = index for Direction 2

In the pattern's PropertyManager, find n2 in the Direction 2 > Spacing and Instances > Number of instances field and find [i,j] in the Modified Instances section.
