Open dwg file in Inventor 2022 fails

[M.Zirk]

Hello,

I try to open an 2018 Autocad file in Inventor 2022 by API.

Dim doc As Inventor.Document = InvApplication.Documents.Open(path, True)

I get the following exception:

Open the file in Inventor by hand is possible.

Open the file in a dwg application is possible.

I have double checked that the Documentname ( here I use the FullFileName) is valid.

What is going wrong?

You gotta use Inventor.Application.Documents.OpenWithOptions( FullDocumentName As String, Options As NameValueMap, [OpenVisible] As Boolean ) As Document

You have to create a NameValueMap. it should work if you do it like this:

Dim options As NameValueMap
Set options = ThisApplication.TransientObjects.CreateNameValueMap
options.Add("ImportNonInventorDWG", True)

Dim dwgDoc as Document
set dwgDoc = ThisApplication.Documents.OpenWithOptions(FullFileName, options, true)

Here is the list of NameValueMap from Inventor Doc

Name Type Valid Document Type Notes

DesignViewRepresentation	String	Part, Assembly	The name of the design view representation. If empty string is input then thhis will be ignored, and the setting in the FileOpenOptions will be applied.
PositionalRepresentation	String	Assembly	The name of the positional representation.
ModelState	String	Part,Assembly	Typically, the ModelState to use should be provided in the form of a FulDocumentName (first argument). But if this is provided separately, you should make sure that it does not conflict with the FullDocumentName argument by providing FullFileName as the first argument rather than a FullDocumentName.
DeferUpdates	Boolean	Drawing	Indicates if any pending updates for the drawing will be deferred when the drawing is opened.
FileVersionOption	Value from FileVersionEnum	All	Valid values for FileVersionEnum are kOpenOldVersion, kOpenCurrentVersion and kRestoreOldVersionToCurrent. If set to kOpenOldVersion, save will not be allowed on the opened document. kRestoreOldVersionToCurrent is valid only if no other versions are open and the current version is not checked out.
ImportNonInventorDWG	Boolean	Imports the DWG file to an IDW if True, Opens it into Inventor DWG if False	When opening non-Inventor DWG files, this method honors the application option to decide between open and import, unless an override is specified in the Options argument.
Password	String	All
ExpressModeBehavior	String	Assembly	The following values are valid for this setting: OpenExpress - Open the assembly in express mode. OpenFull - Open the assembly in full mode. OpenDefault - Open the assembly in the mode it was saved in.
SkipAllUnresolvedFiles	Boolean	All	Indicates to skip all unresolved files and continue to open the document.
DeferFlatPatternUpdate	Boolean	Part	Indicates whether to defer the flat pattern compute or not when open a part with flat pattern in it.

Hello,

thank you for detailed reply and the recommendation.

I tried this but it failed also.

I found out what was wrong.

It was my errorhandler for unhandled exceptions in the addin.

After removing the FirstChance exeception handler no more exceptions occured.
