2015 AddMenuItem not working

Hi

I wanted to use the SolidWorks to Urdf exporter from here: sw_urdf_exporter - ROS Wiki

But unfortunately the menu item under the files Menu to start the export doesn't show up.

Here's the source code:

brawner / SW2URDF / source / SW2URDF / SwAddin.cs — Bitbucket

The corresponding lines responsible for adding the menu item are:

iSwApp.AddMenuItem3((int)swDocumentTypes_e.swDocASSEMBLY, addinID, "Export as URDF@&File", 10, "assemblyURDFExporter", "", "Export assembly as URDF file", "");

iSwApp.AddMenuItem3((int)swDocumentTypes_e.swDocPART, addinID, "Export as URDF@&File", 10, "partURDFExporter", "", "Export part as URDF file", "");

What's wrong with this code?

Thanks
