Delete Attribute Example (C#)
This example shows how to delete the selected attribute.
//-------------------------------------------------------------
// Preconditions:
// 1. Verify that the specified part document to open exists.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Opens the specified part document.
// 2. Selects Cut-Extrude3.
// 3. Adds attribute att 1 to the selected feature.
// 4. Rebuilds the part.
// 5. Deletes attribute att 1.
// 6. Expand Cut-Extrude3 in the FeatureManager design tree
// and examine the Immediate window to verify step 5.
//
// NOTE: Because the part is used elsewhere, do not save changes.
