Add Attribute to Feature and Include in Library Feature Example (C#)
This example shows how to add an attribute to a feature and include
that attribute with the feature if the feature is saved as a library feature.
This example also includes instructions on how to verify that the attribute
is included on each instance of the library feature.
//-----------------------------------------------------------------
// Preconditions:
// 1. Open a new part document.
// 2. Sketch a rectangle and extrude it.
// 3. Sketch a straight slot that fits on a face of
// of the just-created extrude and cut-extrude the slot.
// The cut-extrude should be named Cut-Extrude1.
// 4. Open the Immediate window.
// 5. Run the macro.
//
// Postconditions:
// 1. The Cut-Extrude1 feature is added to the part document with
// an attribute of TestAttribute, which is visible in the
// FeatureManager design tree.
// 2. Examine the Immediate window.
//
// To verify that the attribute is included in a library feature:
// 1. Drag the Cut-Extrude1 feature to the Design Library and
// save the library feature.
// 2. Close the part document.
// 3. Open an existing model document and drag-and-drop the
// just-created library feature on the model.
// 4. Expand the just-dropped library feature in the FeatureManager
// design tree. Cut-Extrude1 and TestAttribute should appear beneath
// the just-dropped library feature in the FeatureManager design tree.
// 5. Close the model document.
