Export part document to 3d pdf with API in c#

The error occurs at line 31 when attempting to export a part document to a 3D PDF using the API in C#.

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 2025\Templates\Sample Part Template.pdf"; oOptions.Value["VisualizationQuality"] = AccuracyEnum.kHigh; String[] sDesignViews = new string[] { "Front", "Top" }; oOptions.Value["ExportDesignViewRepresentations"] = sDesignViews; pdfConvertor3d.Publish(oDoc, oOptions); }

Hi @manasi_patilESZTV,

https://help.autodesk.com/view/INVNTOR/2024/ENU/?guid=ExportToPDF3D_Sample

I was able to get a 3D PDF working by changing/verifying a few things with the NameValueMap. I have Inventor 2024.

The export template file path was slightly different from the one given in the example documentation where the template 3D PDF is further housed in the "en-US" folder (at least on my machine):

//oOptions.Value["ExportTemplate"] = @"C:\Users\Public\Documents\Autodesk\Inventor 2024\Templates\Sample Part Template.pdf"; oOptions.Value["ExportTemplate"] = @"C:\Users\Public\Documents\Autodesk\Inventor 2024\Templates\en-US\Sample Part Template.pdf";

I also removed the "Master" view name from the namevaluemap and just kept the "View1". I see that you changed those names in your code so you already know, but in case someone else is looking here:

//String[] sDesignViews = new string[] { "Master", "View1" }; String[] sDesignViews = new string[] { "View1" };

I also dialed down the dialed down the quality and turned off generating a STEP file. Maybe you'll experience this too, but during the program run, Inventor switched to the background for about a minute, and then came back in the taskbar (I watched in the Windows Task Manager). Maybe these tweaks will help with the issue happening on your end.

Best,

Cody

All together C#:

static void Export3DPdf() { Inventor.Application InvApp = // Inventor.ApplicationAddIn PDFAddin = null; foreach (ApplicationAddIn appAddin in InvApp.ApplicationAddIns) { if (appAddin.ClassIdString == "{3EE52B28-D6E0-4EA4-8AA6-C2A266DEBB88}") { PDFAddin = appAddin; break; } } dynamic pdfConvertor3d = PDFAddin.Automation; Document oDoc = InvApp.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"] = false; //oOptions.Value["ExportTemplate"] = @"C:\Users\Public\Documents\Autodesk\Inventor 2024\Templates\Sample Part Template.pdf"; oOptions.Value["ExportTemplate"] = @"C:\Users\Public\Documents\Autodesk\Inventor 2024\Templates\en-US\Sample Part Template.pdf"; oOptions.Value["VisualizationQuality"] = AccuracyEnum.kLow; //String[] sDesignViews = new string[] { "Master", "View1" }; String[] sDesignViews = new string[] { "View1" }; oOptions.Value["ExportDesignViewRepresentations"] = sDesignViews; pdfConvertor3d.Publish(oDoc, oOptions); }
