write idw to dxf using translator addin with c#

KarlR.J.Wehr — Fri, 12 Aug 2011 09:33:32 GMT

Hi,

I'm trying to export an idw file to dwg using c# and the dwg translator addin. running the code below there is a COMException (E_UNEXPECTED) while executing dwgAddIn.SaveCopyAs.

Similar code works fine with the pdf translator and it also works fine translated to VBA and runnig as a macro within Invetor.

I will apreciate any idea...

Here's the code:

publicstaticvoid SaveAsDwg(Inventor.Application InvApp, Inventor.DocumentInvDoc)

{

Inventor.TranslatorAddIn dwgAddIn =

(Inventor.TranslatorAddIn)InvApp.ApplicationAddIns.get_ItemById("{C24E3AC2-122E-11D5-8E91-0010B541CD80}");

if (dwgAddIn == null)

thrownewException("Could not access DWG translator.");

Inventor.TranslationContexttranslationContext = InvApp.TransientObjects.CreateTranslationContext();

translationContext.Type = Inventor.IOMechanismEnum.kFileBrowseIOMechanism;

Inventor.NameValueMapoptions = InvApp.TransientObjects.CreateNameValueMap();

if(dwgAddIn.get_HasSaveCopyAsOptions(InvDoc, translationContext, options))

{

options.set_Value("Export_Acad_IniFile", @"c:\temp\dwg.ini");

Inventor.DataMediumdataMedium = InvApp.TransientObjects.CreateDataMedium();

dataMedium.FileName =@"C:\temp\test2.dwg";

dwgAddIn.SaveCopyAs(InvDoc, translationContext, options, dataMedium);

}

I executed the code in C# project. It works on my machine. I think the problem is the parameters or the inventor application. Which inventor build are you using? Do you log on windows with an administrator account?

I have some suggestions to diagnose the issues.

1. Verify the ini file "c:\temp\dwg.ini" exists. And the paramter InvDoc is not null at the runtime.

2. If different inventor builds are installed, please verify the correct inventor.exe is started in the code. Set the breakpoint at the entry of function SaveAsDwg. Then you can get the chance to check the process property of inventor.exe in the Windows Task Manager. Verify the expected "Location" (In the Inventor.exe Properties | General tab) is the exact inventor you want to start.

Hi Jeffrey,

many thanks for your replay.

Unfortunately I still can't get it to run. I tested with Inventor 2012 on two workstations and additionally with inventor 2011 SP2.

The ini file "c:\temp\dwg.ini" exists and works while using it with manual export (or with vba code within a macro). InvDoc is set to a document at runtime. The correct inventor.exe is used – I’m getting the application with

(Inventor.Application)System.Runtime.InteropServices.Marshal.GetActiveObject(progId)

I’m using Windows 7 x64. Could that be an issue?

Hello Karl,

What is the message of the exception?

Do you log on windows with an administrator account? If not, please run the execution built by the c# project in Administrator mode.

Hello Jeffrey,

both inventor and visual studio are running 'as administrator'. I also turned off the user acount control, so not sufficient right shouldn't be the cause.

This is the error (in german):

Hello Carl,

Could you upload your c# project and the related ini and idw files? I'll have a try with your porject to see if it can reproduce on my machine.

Hello Jeffrey,

many thanks for your efforts.

I finally found out the reason. I opened the inventor document with the option visible = false. Opening the file that way you can export to pdf but you can't to AutoCAD (dwg or dxf). Opening the file with visible = true solves the problem.

kind regards

Karl

Hi Carl,

I can reproduce your issue if open the drawing document in the invisible mode. Originally, I set this option with true. That's the reason why it works on my machine. Thanks for your reply.
