Create Multibody Macro Feature Example (VB.NET)

This example shows how to create a multibody macro feature using a VB.NET SolidWorks add-in.

'----------------------------------------------------------------------------
' Preconditions:
'  1. Open https://forum.solidworks.com/community/solidworks/api?view=documents.
'     a. Log in.
'     b. Click SolidWorks > API to open the SolidWorks API forum.
'     c. Click the Documents tab.
'     d. Locate the API: C#\VB.NET Add-ins to Create a Macro Feature document.
'  2. If you have a:
'     * 64-bit machine, click attachment,
'       InsertMacroFeature VB.NET Addin Mods for 64 bit.zip.
'     * 32-bit machine, click attachment, VB NET Addin InsertMacroFeature.zip.
'  3. Download and unpack the ZIP file in a convenient location.
'  4. Open and, if necessary, convert the VB.NET solution in Visual Studio.
'  5. Modify the project references to point to your SolidWorks primary interop
'     assemblies.
'  6. Double-click SwAddin.vb in the Solution Explorer.
'  7. Replace Region "ISwComFeature Implementation" with this.
'  8. Replace AddMacroFeature() with this.
'  9. Click Build > Build Solution.
'     The Output window notifies that types registered successfully.
'     If that message does not appear in the Output window, repeat from
'     step 1.
' 10. Open SolidWorks.
' 11. Open
'     install_dir\samples\tutorial\multibody\multi_local.sldprt.
' 12. Click OK in each message box.
'
' Postconditions: 
' 1. When SolidWorks opens, VB Addin appears in the SolidWorks menu.
' 2. When the document opens, the ISldWorks_ActiveDocChangeNotify event fires,
'    and the add-in inserts the macro feature, MacroFeature1, in the
'    FeatureManager design tree.
' 3. The macro feature:
'    * Consumes the part's solid bodies, Fillet5 and Fillet6.
'    * Creates two solid bodies, MacroFeature1[1] and MacroFeature1[2].
'
' NOTE: Because the model is used elsewhere, do not save changes
' when closing it.
