Export 3DPDF using Anark does not seem to work with C# language

[montanceslouis]

Hello and Good day,

I'm using C# and trying to invoke the api for exporting 3dpdf using Anark Core, but i'm having this error at "pdfConvertor3d.Publish(oDoc, oOptions);" please see image below:

The code provided from your API help was working fine using Visual Basic.

Is there a direct Inventor API to do 3dpdf export? The 3rd party app Anark don't seem to work using C#, not so sure.

Thank you! in advance for your feedback.

I don't think the problem is C#. In the help files, there is a C# example on how to export 3D pdf files.

public void Export3DPdf()
        {
            Inventor.Application InvApp = mApp;

            Inventor.ApplicationAddIn  PDFAddin = null ;

            foreach (ApplicationAddIn appAddin in mApp.ApplicationAddIns )
            {
                if (appAddin.ClassIdString == "{3EE52B28-D6E0-4EA4-8AA6-C2A266DEBB88}")
                {
                    PDFAddin =  appAddin;
                    break;
                }
            }

            dynamic pdfConvertor3d = PDFAddin.Automation;

            Document oDoc = mApp.ActiveDocument;
            // Create a NameValueMap object
            Inventor.NameValueMap oOptions = InvApp.TransientObjects.CreateNameValueMap();
            
            oOptions.Value["FileOutputLocation"] = @"c:\temp\3DPDF.pdf";
            oOptions.Value["ExportAllProperties"] = true;
            oOptions.Value["GenerateAndAttachSTEPFile"] = true ;
            oOptions.Value["ExportTemplate"] = @"C:\Users\Public\Documents\Autodesk\Inventor 2019\Templates\Sample Part Template.pdf";
            oOptions.Value["VisualizationQuality"] = AccuracyEnum.kHigh;

            //string[] sProps = new string[1];
            //sProps[0] = "{F29F85E0-4FF9-1068-AB91-08002B27B3D9}:Title";
            //oOptions.Value["ExportAllProperties"] = false; 
            //oOptions.Value["ExportProperties"] = sProps;

            String[] sDesignViews = new string[] { "Master", "View1" }; 
            oOptions.Value["ExportDesignViewRepresentations"] = sDesignViews;

            pdfConvertor3d.Publish(oDoc, oOptions);

        }

In your code, I see some other options. Maybe one of those is the problem. Can you try to use only the options that are also in the help file?

Thank you for your input.

Yes, this code works fine on standalone project. As well as the visual basic.
But on over the Addin, the C# code is not working, only the visual basic.
By the way, the project that i'm doing is a separate addin for Inventor.

Thanks again, JelteDeJong
