Assembly unable to update.

[spencer]

This is a really odd issue that's really making things difficult. Basically, I have an assembly that can be opened and viewed, but performing an update/doing anything that would cause an update gets the instance stuck for no obvious reason.

To be more specific, what I'm looking at is a main assembly of a project we did back in 2015(7688 parts according to Inventor), about a month ago the customer asked us to quote some modifications to the system so we opened it up, migrated to 2019, did a save-as on the main assembly and added the requested features over the course of a few days. So yesterday I get the go-ahead to actually get started, but any time the assembly it just gets infinitely stuck trying to perform the update.
I'll list everything I've tried, but frankly I'm running out of ideas.

So far I've tried (And all with the same result):

- Doing the exact same thing half a dozen times hoping something would change

- Not allowing updates until the assembly was loaded in full

- Let it calculate for 12 hours (Never explicitly failed, but was still going)

- Deleting 2 sick constraints before allowing the assembly to update

- Deleting all constraints before update

- Deleting some sub-assemblies

- Deleting EVERYTHING

- Restoring an old version from when we first started working on it

- Doing a Save-As on the assembly

- Opening in Inventor 2018

- Opening in Inventor 2020

- Consulting a priest

- Updating sub-assemblies that were marked for update

- Disabling all Inventor add-ins

I'm kind of out of ideas at this point.

Well you seem like you are having a good time 🙂

I notice that you had originally made the assembly in 2015, so I assume it would be made in Inventor 2016 (at the latest). If you still have access to the 2016 software, give it a go in that, see if you can load it up.

Otherwise, I was having an issue where I tried to open a decent-sized assembly (only about 100 parts or so) and the file would take FOREVER to open. I ended up changing my project file and that seemed to solve the issue, so maybe it is something similar for you? Your project file could be referencing itself.

One other thing to check is to try opening it and getting it to freeze again, which shouldn't be hard. When this happens, open your task manager (CTRL+ALT+DEL) and check what is taking up most of your processing power. This might give you a clue as to if it is something in Inventor, or maybe another program that it is running in tandem with.

Spencer,

Let me introduce you to my favorite new command, Save All. Seriously, I found that this will force ALL files to migrate and solve a lot of these issues. I found out that using task scheduler, or rebuild all did not necessarily migrate all the files for various reasons. Save All seems to force the issue. Try this and see if it helps.

Cheers,

Todd

No dice after performing a Save All, nor with making a new project file. Right now I'm trying to see if the main assembly could be saved out as a .stp file without updating, but it's not looking good so far.

HI @spencer 

If you close all your files and then you edit your Project file (*.ipj) and expand the Options node in the Edit Project pane, you'll see the Using Unique File Names option, try setting this to No and then opening the assembly.

More on this setting and what is does/does not do:

I hope this helps.
Best of luck to you in all of your Inventor pursuits,

No change unfortunately, and while I did manage to get a .stp file saved of the assembly, it seems to be un-openable so far

Hi! Have you installed 2019.4? We have a fix in 2019.4 to address a Derive related issue preventing Derived part from updating after the source part has been changed.

Please install 2019.4 update and see if it works for you. Or, please send me the files directly (johnson.shiue@autodesk.com). I would like to understand the behavior better.

Many thanks!

I updated to 2019.4 but the issue persisted. Unfortunately I don't think I'll be able send it since the assembly + dependencies is easily 10gb, plus it's an entire design for a system we do.

A co-worker that is currently traveling said the version he has saved locally on his machine works, so hopefully when he gets his version synchronized back I might be in better shape.

Hi! If you do Rebuild All in the assembly or in the part, does it help? Is it a derived part?

Many thanks!
