Error Message about Navisworks API for listing the clashes in C#...

[bnn987654321]

I am using the Navisworks API for listing the clashes in C#.
But I get the error message.

[ERROR MESSAGE]
Unable to cast COM object of type 'System.__ComObject' to interface type 'NavisWorksAPI6.InwPluginsColl'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{D74F889B-01BA-11D5-A066-00B0D011BBC8}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

and source code is...

foreach (InwPlugin plugin in m_state.Plugins())
{
    if (plugin.ObjectName == "nwOpClashElement")
    {
        m_clash = (InwOpClashElement)plugin;
        return;
    }
}

Hi bnn987654321 ,

Which version you are using? The following C# code works well at my side on Navisworks 2011:

 NavisworksAPI8.InwOpClashElement   m_clash = null;    

 foreach (NavisworksAPI8.InwBase oPlugin in oState.Plugins())
 {
            if (oPlugin.ObjectName == "nwOpClashElement")
                {
            m_clash = ( NavisworksAPI8.InwOpClashElement)oPlugin;
                    break;
            }
  }

If you still have the problem, could you share a small, non-confidential sample?

Best regards,
