Create a button to clear all active memory (similar to what CREO offers) so we don't have to restart Inventor.
Anytime I need to clear the active memory in Inventor I have to close and start a new session. There should be a simple button on the ribbon somewhere (or in a dropdown) that allows a user to clear all active memory if they have no files open. CREO offers this and it is a great tool to have! .... Unless I'm missing something in Inventor and there is a way to clear active memory (I don't think there is)?
To the best of my knowledge, Inventor flushes memory of components when they are closed. Of course, all files that reference a specific component must be closed before the component is flushed.
Interesting. Is there someone from Autodesk, who would know for sure, that can confirm this?
If it is the case, it doesn't seem to work all the time. I'm sure there are times in which I have had all files closed and not getting accurate output from changes to code until I restarted Inventor.
Maybe, if closing is supposed to flush the memory, they give us the button anyway so we can manually do it in those instances active memory does not seem to have been cleared?
The general goal is that closing a document will clear the memory that it was using but if there are cross-document references (eg a part in an assembly in a drawing etc) that are all open concurrently then yes, there's likely room for memory mgmt improvements....
As you already know closing/restarting Inventor is currently the best way to clear memory usage; hence your idea.
Another good practice is to regularly delete everything from your %temp% folder, (after closing all running applications).
Sounds like the Clear All Active Memory button has a practical use not currently being performed (at least not completely).
.... Maybe it could even be a little more robust than just a 'clear memory button' and let the user know if something couldn't be cleared from memory because it is open somewhere, and what that something is.
It sounds like you have another good case for the creation of this button. Please click the "Vote" button at the bottom of the first post to show the Autodesk team this is something they should escalate and look at.
I believe I have exposed how Autodesk clears the cache:
DocumentObject gets set to Nothing when inventor closes that Document. I believe What I need to do is rewrite this code to say for All Documents in ThisDoc.Document or something like that and then run these codes on it.
Sub Main ClearCache()
Dim oDoc As Document = ThisDoc.Document
oDoc.ReleaseReference
'Application.ExitThread
oDoc = Nothing
DocumentObject = Nothing
uiEvents = Nothing
inventorApplication = Nothing
AppEvents = Nothing
oFileDlgEvents = Nothing
Try
System.Runtime.InteropServices.Marshal.ReleaseThreadCache
'System.Runtime.InteropServices.Marshal.FreeCoTaskMem
'System.Runtime.InteropServices.Marshal.FreeBSTR
'System.Runtime.InteropServices.Marshal.FreeHGlobal
System.Runtime.InteropServices.Marshal.CleanupUnusedObjectsInCurrentContext
'System.Runtime.InteropServices.Marshal.Release
'System.Runtime.InteropServices.Marshal.ReleaseComObject
'System.Runtime.InteropServices.WindowsRuntime.WindowsRuntimeMarshal.FreeHString
'https://renenyffenegger.ch/notes/Microsoft/dot-net/namespaces-classes/System/Runtime/InteropServices/Marshal/index
'System.Runtime.InteropServices.Marshal.FreeHGlobal(inventorApplication)
Catch
End Try
'AccessibleObject = Nothing
'DataObject = Nothing
'Application.CutCopyMode = False
'System.GC.Collect()
'System.GC.WaitForPendingFinalizers()
'ThisApplication.kNeverSaveMemoryMode(True)
'ThisApplication.Documents.ReleaseReference
'ThisApplication.Documents.CloseAll(True)
End Sub
My bad; I missed your vote at first glance. Thank you for voting!!
It may take some time. I have seen (recently) a topic go from "Gathering Support" to "Future Consideration" just a few weeks ago and the topic started back in 2013. 9 years later, this issue (link below) is finally being considered (hopefully).
Hopefully we can get Autodesk to advance this topic much sooner than 9 years from now. Either way, all is not lost, yet!
If you know any other users, please consider passing the link to this topic to them and encourage them to vote. If enough of us do that, we may see action on this sooner rather than later.
We want the button to be an actual button on a ribbon or a dropdown somewhere without having to hunt down and edit code. This is very cumbersome for the average user (and prohibitive for some).
Your method is probably good, but we still need a button!
@nedeljko.sovljanski i updated my code just now. This works pretty well (no errors). But I cant seem to figure out how to get task manager to show the memory dropping not sure if it is working. do you have a way to test to see if inventor holds on to something after this code is run?
