Pattern Features and their Feature Data Objects

To create a pattern feature:

1. Open a part (or an assembly for a local pattern).

2. Pre-selection of entities may be supported for some pattern features. Refer to the remarks and examples in the pattern-specific feature data interfaces.
    

   To create an instance of...	Call IFeatureManager::CreateDefinition(swFeatureNameID_e...)
   IChainPatternFeatureData	swFmLocalChainPattern
   ICircularPatternFeatureData	swFmCirPattern
   ILocalCircularPatternFeatureData	swFmLocalCirPattern
   ICurveDrivenPatternFeatureData	swFmCurvePattern
   ILocalCurvePatternFeatureData	swFmLocalCurvePattern
   IDerivedPatternFeatureData	swFmDerivedLPattern
   IDimPatternFeatureData	swFmDimPattern
   IFillPatternFeatureData	swFmFillPattern
   ILinearPatternFeatureData	swFmLPattern
   ILocalLinearPatternFeatureData	swFmLocalLPattern
   ISketchPatternFeatureData	swFmSketchPattern
   ILocalSketchPatternFeatureData	swFmLocalSketchPattern
   ITablePatternFeatureData	swFmTablePattern

    

3. Modify properties on the pattern-specific feature data object.

4. Create the pattern-specific feature by calling IFeatureManager::CreateFeature.
    

To edit a pattern feature:
 

1. Call IFeature::GetDefinition to get the pattern-specific feature data object.
    
2. Call AccessSelections on the pattern-specific feature data object.
    
3. Modify properties on the pattern-specific feature data object.
    
4. Call IFeature::ModifyDefinition if you modified the feature or ReleaseSelectionAccess on the pattern-specific feature data object if you did not modify the feature.
