IFirstFeature Method (IModelDoc2)

Gets the first feature in the document.

.NET Syntax

Visual Basic (Declaration) 
Function IFirstFeature() As Feature
Visual Basic (Usage) 
Dim instance As IModelDoc2
Dim value As Feature
value = instance.IFirstFeature()
Feature IFirstFeature()
Feature^ IFirstFeature(); 

Return Value

First feature in the document



This method:

  • is identical to IPartDoc::FirstFeature, but is available on the IModelDoc2 interface to include access to assemblies and drawings.
  • can access the first feature, even if it is suppressed.
  • returns features in the current order for the model, and this order changes when the model is edited.

Your application should not assume that:

  • features retain the same relative or absolute position throughout the model’s lifetime. For example, you should not assume that Sketch1 always appears before Sketch2.
  • any feature has a specific name. Because features 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.

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