Inventor API - C# Visual Studio
i expect that you are getting an exception and you want to know what the problem is. To help you it would be helpfull if you could tell:
- What does the exception description say?
- At which line do you get the exception?

Danke für die schnelle Antwort hier ein Screenshot zu der Ausnahme.

Usually you get this exception if the active document in inventor is not a part document. So this will not work for assemblies for example.

Ah ok verstanden.
Kannst du mir aber vielleicht noch weiterhelfen und mir sagen wie der Code aussehen muss wenn ich diese Baugruppen und Bauteile auslesen möchte?

"Ah ok understood.
But can you help me further and tell me how the code must look like if I want to read these assemblies and components?"
Deepl translation
Danke hat mir alles schon mal sehr viel geholfen. Bin nun auch schon einiges weiter und möchte nun die Bauteile in JT exportieren.
Bekomme hier aktuell noch folgende Fehlermeldung.
Was genau hat es damit auf sich?

"Thank you everything has already helped me a lot. I am now quite a bit further and would now like to export the components in JT.
I still get the following error message."

Vielen Dank für deine Antwort.
Hier natürlich der Source Code.
Habe nun einen anderen versuch unternommen der joch leider auch noch nicht klappt. Vllt ist es so nun besser nachzuvollziehen? 🙂
Im Prinzip geht es mir eben darum jedes Teil als .jt einzeln abzuspeichern.

Ich bekomme 0 byte-Dateien als ergebnis

"Thanks for your answer.
Here of course the source code.
I have now made another attempt which unfortunately does not work yet. Maybe it is now better to understand? 🙂
In principle, I just want to save each part as .jt individually."
"I get 0 byte files as result"
Deepl translation
Thank you very much for your answer.
I understood what you meant and of course I tested it immediately.
Unfortunately, it still drops files with 0 bytes?
try
{
dataMedium.FileName = path + oCompOcc.Name + ".jt";
inventor.SilentOperation = true;
if (oCompOcc.DefinitionDocumentType == DocumentTypeEnum.kPartDocumentObject)
{
//var oNewDoc = (PartDocument)inventor.Documents.Add(oCompOcc.DefinitionDocumentType, "", false);
//translateAddIn.SaveCopyAs(oNewDoc, translateContext, nameValueMap, dataMedium);
translateAddIn.SaveCopyAs(oCompOcc.Definition.Document, translateContext, nameValueMap, dataMedium);
}
