Get Faces Associated with Feature Example (VB.NET)

This example shows how to eliminate multiple feature faces.

NOTE: In SOLIDWORKS, a face is the result of evaluating a feature. A face can be owned by several features. IFeature::GetFaces returns all faces owned by a feature. This is different from faces highlighted in the user interface when a feature is selected, because the user interface filters out multiple feature faces. This filter is for display purposes only. An application must use IFace::GetFeature to filter out multiple feature faces. This method returns only the oldest feature from a face; that is, the first owning feature in the FeatureManager design tree.

' Preconditions:
' 1. Open a part document.
' 2. Select a feature in the FeatureManager design
'    tree.
' 3. Open the Immediate window.
' Postconditions:
' 1. Gets the name of the feature and number
'    of faces.
' 2. Colors the faces of the feature blue. 
'    NOTE: The faces are the same faces as if 
'    you selected the feature in the user interface.
' 3. Examine the Immediate window and graphics area.
