Get Faces Associated with Feature Example (VBA)

This example shows how to get the faces associated with a feature.




' Problem:

'       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 this

'       feature. This is different from faces highlighted in

'       user-interface when feature is selected. 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 face; that is, the

'       first owning feature in the FeatureManager design tree.


'       This example shows how to eliminate multiple

'       feature faces.


' Preconditions:

'       (1) Part is open.

'       (2) Feature is selected in the FeatureManager design tree.


' Postconditions: Faces of the feature are colored blue.

'       The faces are the same faces as if the

'       feature was selected through the user-interface.
