Inventor 2021.2.1 - Model Disappears when hovering over coil feature in browser

[jweiss1313]

I have an Inventor 2021.2.1 created auger file.  When the user hovers over various features in the browser, featured highlight in the graphics window.  In the auger file (see attached, when you hover over the Coil2 feature, the model and sometimes the view cube disappears.  Sometimes you can get it back by hovering or clicking on other features and sometime you need to close the file and open it again.  I have opened this file and three different engineering workstations all running Inventor 2021.2.1 and all of then have the same result.  Either the file or Inventor 2021.2.1 have graphics bug.

I've attached two screen captures that show what happens when I highlight on one of the Revolution features and what happens when I hover over the Coil2 feature.  

Thank you in advance to anyone who can take a look at this issue and help us solve the problem.

I see the same graphics issue, but I find that selecting any other feature, sketch, or work feature restores it.  Haven't yet found a situation in which it couldn't be restored that way.

Update: I discovered that if I edit the Coil2 feature and increase the pitch by .005 in, the graphics issue goes away.  If I return it to its original, or go a bit smaller, the issue returns.  Good luck chasing this one!

Hi! This is a corruption case in the scene due to the bad coil computed in very old Inventor release (R5). I have used an internal tool to fully migrate the features and fix up the projected sketches on 2021. Now, the part should work fine. Please take a look at attached part.

Many thanks!

Thank you Johnson for migrate the part and fixing the issue.  I appreciate your help!

Thanks for your help!

FYI - iProperties for the file that you Attached indicate last saved in 2021.1, not 2021.2.1 (2021.2.2 now available).

Interesting issue though. Inventor 5 huh?  That was about when I started using Inventor.

Hello. Can you show me how you did the fix?

[johnsonshiue]

Hi Yildiray,

If I recall this correctly, it was repaired by updating the feature birthday. It somehow helps. But, there is no guarantee the same thing applies to you. Also, it is an internal proprietary tool that I cannot share in public.

Please send me the file directly johnson.shiue@autodesk.com. I can take a look and see the best path forward.

Many thanks!

Hello Johnson,

I have another Inventor 2021.3.1 part where the coil feature disappears when you hover over it in the browser.  Would you be so kind to run your "magic" internal migration tool on the attached file to see if you can fix it for us?

Thank you so much for your help.  I appreciate it!

[jweiss1313]

Hello Johnson,

I have one more file for you to fix.  Thanks!

Hi John,

Attached are the two fixed files. The REV one is less successful since there seem to be missing some parameters or reference geometry. I could not make sense out of Extrude18 and after. But, the features are all upgrade to 2021.

Many thanks!

[jweiss1313]

Johnson,

Once again you saved us!  Thank you so much for repairing both files for us.  You're the best.

Hi

We have the same issue with a compagny that are making gears.

How can I help those engineers that has a lot of files made in pre. Inventor 2021?

[johnsonshiue]

Hi! Without seeing the files, I cannot say your issue is the same as the original thread. Please feel free to send me an example directly johnson.shiue@autodesk.com. I am more than happy to take a look and see what I can do.

Many thanks!
