Insert and Save Virtual Assembly Example (C#)

This example shows how to create and save a virtual sub-assembly.

//-----------------------------------------------------------------------------
// Preconditions:
// 1. Open an assembly document.
// 2. Rename the namespace of this macro to match your C# project's name.
// 3. Open an Immediate Window.
// 4. Run this macro.
//
// Postconditions:
// 1. Tools > Options > System Options > Assemblies >

//    Save new components to external files is selected,

//    and InsertNewAssembly is called, passing in FileName

//    to save the sub-assembly:
//    a. MyTestValveAssembly<1> displays in the FeatureManager design tree.
//    b. MyTestValveAssembly.sldasm is saved in the assembly's directory.
// 2. Next, Tools > Options > System Options > Assemblies >

//    Save new components to external files is de-selected,

//    and InsertNewAssembly is called, passing in FileName

//    to save the sub-assembly.
//    a. A virtual sub-assembly displays in the FeatureManager design tree.
//    b. The FileName parameter is ignored, and the virtual sub-assembly

//       is not saved.
// 3. The Immediate Window displays the error codes

//    as defined in swInsertNewAssemblyErrorCode_e.
