exception while saving the activeDocument on V2026 and after migration

[n_mullerLMQ8C]

I have switched our application (which uses the Inventor and the inventor api) to inventor2026. Then I have processed a migration... the call to the save() function (activeDocument.save) triggers now a n exception. I have tried to call the save2() function instead... then we land in Bug Report formular.

As I have refined the saves at different stages (one save after each component processing), I saw that this problem is triggered on 5 components among 20. This leads me to the first impression that the problem is due to an incompatibility in data.

I am posting the visual basic code where the problem surges. And can optionally supply more code...

PS : is there anywhere any Inventor api reference guide for developpers ?

PS : the faulty save is at line 345 in TürDesigner.vb

To come tot he point were the problem surges, you have to do the following sequence

(pay attention : in order to actually trigger the problem, you have to uncomment the line _appInv.activeDocuemnt.save() at line 345)

• Start autodesk inventor professional 2026
• In the start home page select TürDesigner.iam (double click)
• It will load this
• Then in „ilogic“ panel (near Modell panel) (upward links), right click on TürDesigner
• Select „execute the rule“ or „Regel ausführen
• In the file browser, choose the file at the bottom (cadTest.csv)
• In the new window, select „ausführen“ (execute)

The modules where the cause might be are the following :

• FlügelRahmen
• TürRahmen
• Beschläge
• Pfostenkonstruktion
• Verbreiterungsprofile

(I have tested everyone in isolation)

Addition to the former investigations :

In der Folge von letzten Untersuchungen ist bestätigt dass die Probleme am speichern von Modelen entstehen durch der Benützung von folgenden Primitiven :

• Parameter()
• Replace()

In den folgenden Modulen :

• FlügelRahmen
• TürRahmen
• Beschläge
• Pfostenkonstruktion
• Verbreiterungsprofile
• GanzGlasFüllung

(das Problem verbreitet sich durch ein Struktur Mismatch von Daten bis auf dem Speichern…)
