Move Assembly Components to New Folder Example (C#)

This example shows how to move selected assembly components to a newly created folder in the FeatureManager design tree.

// Preconditions: Specified assembly document to open exists.
// Postconditions:
// 1. Assembly document is opened.
// 2. The valve<1> and valve_guide<1> components are selected.
// 3. Folder named Folder1 is created in the FeatureManager design tree.
// 4. The valve<1> and valve_guide<1> components are moved to Folder1,
//    which you can verify by expanding the Folder1 folder.
// NOTE: Because the assembly document is used elsewhere,
// do not save any changes when closing the document.
