Inventor frame generator not updating with sketch

[Anonymous]

Hi,

I have a sketch that is driving my frame. When I change the sketch the frame does not update.

I am using Inventor 2021.

Can someone please diagnose whats the problem with my file?

Hi! As of 2021.2 and later updates/releases, the non-updating issue should have been fixed. If you are still seeing the problem, it could be a separate issue. Please share the files here or send them to me directly. I can follow up with the project team to understand the behavior better.

Many thanks!

I have the same issue: tried ungrounding the skeleton part that contains the sketches on which the FG is based; tried editing the skeleton part before opening the FG assembly, and with the FG asssembly open. Same thing. Now I have a gang of FG members that show the correct line if I edit them with FG, but are behaving as if the line is where it was before. How can I trust any of it now? Various View Reps, No LOD's. Any advice welcome asap!

Hi! I believe it was a Frame Gen bug in 2021 or 2022 which got fixed in later updates. Please make sure the applicable updates are installed. If it does not help, please share an example that exhibits the behavior here. Forum experts can help take a look.

Many thanks!

Hi Johnson,

I'm using 2021.4.1 Build 397 which I thought was the latest.

Do you mean if I opened it in a later version it would correct itself,
or do you mean it shouldn't happen in a new assembly created in a later
version?  If the latter, this is of more academic interest as I need to
get the assembly corrected asap. There are two of us collaborating on
this work remotely, and I'd be reluctant to tackle the upgrade just now
if it can be avoided.

It's a big dataset to share - which I could do, but how?

Best regards,

Simon

Hi! I am sorry I cannot tell where the problem is without seeing the files. Please share it on a cloud drive of your choice and grant access to me johnson.shiue@autodesk.com. I can take a look and see why Frame members are not updating.

Many thanks!

This solved my issue aswell

many thanks!

Frame Generator not updating has been a problem since I started using it, 2015 version

No rhyme or reason to it. If nothing else works shut Inventor down and restart, this works most times. In really bad cases reboot the computer.

Hi Mario,

The causes of not updating may not be the same. There are two types of problems I have seen. 1) Somehow the reference sketch in the frame subassembly becomes corrupted. The associativity between the source geometry and the reference sketch geometry is lost.

2) The frame subassembly is repurposed or demoted from its original hosting assembly. This is not a supported workflow. The frame's editability will be limited when it has been taken out of its authoring context.

Please feel free to share an example that exhibits the behavior. I can help take a look to see if this is a known issue and what can be done with it.

Many thanks!

Seriously Johnson, I have spent a lot of time on this forum at my previous job. You are very knowledgable about Inventor and are a wonderful resource for this forum.

But when you toe the autodesk line about ignoring very long time Inventor issues it does not look good.

If I sent you a file with that issue happening at a certain time, when you opened the file the frame would update the same as it usually does when I restart Inventor. 

Like every other user who uses FG I live with the problem, does not happen often enough to discourage me. Just a PITA when it does

Hi Mario,

I am sorry if I missed an email. I am not sure how you sent me the file. I just checked by emails for past three years. I did not see anything from you. Did you send it to johnson.shiue@autodesk.com?

Many thanks!

Hi I'm using 2022 and this issue has presented itself, i read in the thread that it was fixed in 2021. 

[johnsonshiue]

Hi Chris,

I would like to check a few things. This behavior happens from time to time. Sometimes it was indeed a bug. But, it could also be a legitimate failure. Please make sure 2022.4.1 update is installed.

1. Have the skeletal part and the frame subassembly been repurposed in another assembly (different than the one created the frame originally)?

2. Has the line in the skeletal part been deleted and recreated?

If neither applies to you, it could be a bug. Please share the files in zip here. I would like to understand the behavior better.

Many thanks!

Hi,

I'm having this issue as well in inventor 2022.5.1 . I have a master sketch in which I adjusted the frame length. The frame member did update but now it's offset from the frame line it's attached to. This assembly was copied from another assembly using design assistant, if that matters.

Any help would be appreciated.

[jj.pieschl]

Also, if I edit it using frame generator it appears to go back on to the frame sketch that it's supposed to be attached to. The second I exit the command it goes back to being offset...

[johnsonshiue]

Hi! Please note that the specialized components workflow like Bolted Conn, Cable&Harness, Design Accelerator, Frame Gen, and Tube&Pipe require the components stay within the original hosting assembly. If they are demoted, promoted, or repurposed in a different assembly, the associativity will be broken. If possible, please share the files in zip with me directly johnson.shiue@autodesk.com. I would like to understand the behavior better.

Many thanks!

I've got the same issue with Inventor 2024.

I used edges of a surface body to place my frames. 

Adding a 3D sketch in my surface body resolved the problem !

I even didn't had to replace my frames. 

Hope this helps 😉
