IFirstFeature Method (IPartDoc)

Gets the first feature in the part.

.NET Syntax

Visual Basic (Declaration) 
Function IFirstFeature() As Feature
Visual Basic (Usage) 
Dim instance As IPartDoc
Dim value As Feature
value = instance.IFirstFeature()
Feature IFirstFeature()
Feature^ IFirstFeature(); 



This method returns features in the current order for the part, and this order changes when the part is edited.

Your application should not assume that:

  • features retain the same relative or absolute position throughout the part’s lifetime. For example, you should not assume that Sketch1 always appears before Sketch2.
  • any feature has a specific name. Because feature can be renamed, you cannot assume that the first reference plane feature is named Plane1.

When traversing the FeatureManager design tree, your application should use IFeature::GetTypeName2 and IFeature::GetSpecificFeature2 to identify specific features instead of relying solely on IFeature::Name.

This method returns features in the model definition order, which is not the same as the order displayed in the user interface. See ITreeControlItem for details.

If a feature is suppressed, then this method can still access the feature.

To access the next feature in the FeatureManager design tree and subfeatures, use IFeature::GetNextFeature or IFeature::IGetNextFeature and IFeature::GetFirstSubFeature or IFeature::IGetFirstSubFeature.
