How to Import a Parasolid file in C# as a Standalone build

Hello,

 

I've just started working with SolidWords and wanted to see if it was possible to create a C# Project to start Solidworks as a background process (not visible at all) and load a Parasolid file, but Im not finding the correct documentation to help me out. The closest link I found was https://forum.solidworks.com/thread/94623, which was great already, but at the end didnt help me get through with it.

 

This is what I have so far: A simple Console Project with the following code

 

class Program
{
    static SldWorks.SldWorks _swApp;


    static void Main( string [ ] args )
    {
        try
        {
            Test( args );
        }
        catch ( Exception ex )
        {
            Console.WriteLine( ex.Message );
        }


        if ( _swApp != null )
        {
            _swApp.ExitApp( ); //Exits SolidWorks running in the background
            _swApp = null;
        }
    }


    static void Test( string [ ] args )
    {
        SldWorks.SldWorks _swApp = new SldWorks.SldWorks( ); //Correctly starts a new instance of solidwords if one isnt opened already
        ModelDoc2 swModel;


        swModel = _swApp.ActiveDoc as ModelDoc2;


        string fileName = null;
        string argString = null;
        int Err = 0;


        fileName = "D:\\temp\\HEAD-A-0018.x_t";
        argString = "r";


        dynamic importData = _swApp.GetImportFileData( fileName );
        swModel = ( ModelDoc2 )_swApp.LoadFile4( fileName, argString, importData, ref Err );


    }
}

This is throwing the following exception:

An exception of type 'System.Runtime.InteropServices.COMException' occurred in System.Dynamic.dll but was not handled in user code

Additional information: Element not found. (Exception from HRESULT: 0x8002802B (TYPE_E_ELEMENTNOTFOUND))

What I could tell was that "importData" variable has a NULL value, the "fileName" path results in a valid file and that swApp is not null. Also added some Solidworks DLLs to the References of this C# Project .

 

Can anyone point me the way to correct this? Because I havent been able to figure it out so far =/

 

Thank you!
