Check If there are any recomputable changes were done to active 3Dmodel (IAM)

[Maxim-CADman77]

I'd like to know is it possible to check whether any recomputable changes were really done to active 3Dmodel (IAM) using API.

Most close search results by string "Recomputable Changes" within CHM is

SaveOptions.PromptSaveForRecomputableChanges () Property As Boolean

which is not what I'm searching for...

Public Sub upda()
Dim a As Document
Set a = ThisApplication.ActiveDocument

msgbox a.RequiresUpdate
End Sub

Both RequiresUpdate and Dirty Properties has False value.

Any other ideas?

For some assemblies prompt to save changes on close is shown.

This happens not on all IAMs and only if option "Prompt to save re-computable changes" (on "Save" tab) is enabled while option "Express mode" (on "Assembly" tab) is disabled.

API calls return "False" value for all four Properties that I think might have relation:  RequiresUpdate, Dirty,  IsOpenExpress, IsOpenLightweight.

I still would like to know how to determine such situation via API.

I still need help with this question.

Thank you, but I still have some concerns.

For example I have such a sample IAM which says nothing on open but asks to save it on close (because of some yet unknow recomputable updates).
I then disable auto-start of all the add-ins (just in case), discard saving the IAM, re-start inventor and re-open the IAM.

Then I open About Inventor window and press Ctrl+Shift+D and see that none of the present entries is marked in any way:

I then close this window and press close the IAM. It suggests to save changes. I instead cancel the close operation. And re-open the diagnostic info window. Now I see the two check-boxes marked "Database considered Dirty" and "eUpdateCommand" (and DirtyBits="0X10"):

I wonder if I can receive any of this flags through API just after open (without attempt to close)?

@Maxim-CADman77,

Can you please provide reproducible steps and data set to test? please make sure that files are non confidential.
