Insert New Virtual Component Example (C#)

This example shows how to insert a new part as a virtual component in an assembly and save it to an external file.

// Preconditions:
// 1. Open:

// <SolidWorks_install_dir>\samples\tutorial\smartcomponents\stepped_shaft.sldasm
// 2. A planar face on the assembly is selected.
// 3. Rename the namespace of this macro to match your C# project name.
// Postconditions:
// 1. The new part is inserted as a virtual component in the assembly.
// 2. The virtual component is saved to an external file,
//    and its name changes in the FeatureManager design tree.
// NOTE: Because this assembly is used in a SolidWorks online tutorial, do not
//       save the assembly when you close it.
