Cannot generate D1Spacing in Linear Pattern

Question asked by Prarthana Bataju on Jul 30, 2015

I am trying to generate some Linear pattern in my CAD data in SolidWorks using LocalLinearPatternFeatureData with some spacing using SolidWorks API for C #. When I try to generate number of patterns using only D1TotalInstances, it works. However when I try to apply some spacing within it ... using D1Spacing, it fails though it returns true The real problem is, is display given pattern number and spacing value when I check it directly into LocalPattern I already tried rebuilding it Here is my code:

Private void ChangeLinearPatternLength ( ModelDoc2 SwModel , string StrCompPattern , double LengthMultipleVal , bool IsAdditionalNum = false )
  
{
  
ISelectionMgr SwSelMgr = SwModel . ISelectionManager ;

  SwModel
. ClearSelection2 ( true );
  SwModel
. Extension . SelectByID2 ( "NEC (B) _SA03-1 @ NEC_ASSY / SVKA (B) _SSA09-1 @ NEC (B) _SA03 " , "COMPONENT" , 0 , 0 , 0 , false , 0 , null , 0 );
  
AssemblyDoc AssDoc = ( AssemblyDoc ) SwModel ;
  AssDoc
. EditAssembly ();
  SwModel
. ClearSelection2 ( true );

  SwModel
. Extension . SelectByID2 ( "LocalLPattern1 @ NEC (B) _SA03-1 @ NEC_ASSY / NEC (B) _SSA09-1 @ NEC (B) _SA03" , "COMPPATTERN" , 0 , 0 , 0 , false , 0 , null , 0 );
  
Feature SwFeature = SwSelMgr . GetSelectedObject6 ( 1 , - 1 );
  SwModel
. ClearSelection2 ( true );

  
string StrPatterName = SwFeature . GetTypeName2 . () ToUpper ();
  
switch ( StrPatterName )
  
{
  
case "LOCALLPATTERN" :
  
Debug . Print ( "Linear Pattern:" + SwFeature . Name );
  
EruoshieilLinearPatternFeatureData LlpDefinition = default ( EruoshieilLinearPatternFeatureData );
  LlpDefinition
= ( EruoshieilLinearPatternFeatureData ) SwFeature . getDefinition ();

  LlpDefinition
. D1Spacing = ( double ) 300 / 1000 ;
  LlpDefinition
. D1TotalInstances = 4 ;

  bool status
= SwFeature . ModifyDefinition ( LlpDefinition , SwModel , null );
  SwModel
. FeatEdit ();
  SwModel
. ShowConfiguration2 ( "Default-_Flexible1" );
  
Break ;
  
}

  
}

 

Can anyone suggest me what am I missing or doing wrong here.
