Parts/Hole Disappearing

[Anonymous]

Hello all,

    I'm having a series of issues with a large Inventor model:

1. Holes keep disappearing from the assembly. Though they are 'there' and all screws are constrained to them. I would redefine one of the hole feature's sketch and ALL the holes would show up. I did a rebuild all and that seemed to fix the issue. They now show up in the .iam, .ipn and drawing. Can anyone comment on why this happened?
2. Parts keep disappearing (or are getting automatically suppressed) from a presentation view, and thus the drawing. I unsuppress one of the parts that is "missing" and the other 8 magically appear. I reexplode everything and then it happens again. Any suggestions?

The model is proprietary so I cannot post it. Sorry.

How were these holes created? punch tool or just regular hole feature or bolted connection generator?

Post computer specs, OS/CPU/Ram? and include the graphics card and current driver version.

Any imported files in this large assembly?

Aaron,

Were the holes created in the assembly, or the parts?  Fair to assume these missing parts are directly related to the missing holes?

Can you either post your files or some images?

What version are you running?

If this solved your issue please mark this posting "Accept as Solution".

Or if you like something that was said and it was helpful, Kudos are appreciated. Thanks!!!!

The holes were created using the regular hole feature. No imported parts, Here are the computer specs:

• Dell Precision T3500
• Intel processor 3.2 Ghz
• 12 gig RAM
• 64 bit operating system.

Graphics card I do not know, but I can tell you we have some pretty awful graphics cards.

Thanks!

The holes were created in the assembly. There maybe have been a missing link betwen the ipn and iam for the view with the missing parts, so I redid that so we'll see if that works. We use 2014.

If they were created in the IAM as assembly features, then they reside in the assembly. You would need to push them down to their respective IPT files for them to show up on the IPT.

That's the reason they are disappeared from the IPN file. When you "Explode" and move the parts around the holes will disappear

This holes need to be called out in an installation drawing (a.k.a. holes are drilled onsite). They can not be placed in the IPT. Thank you thought!

Sorry to be the bearer of bad news then, they won't appear in your IPN for this reason. Because the hole at the Assembly level resides in a particular location within the IAM file. If they did show up in the IPN file, as you moved the IPT files to get the desired explosion, the holes would then move on the parts as they move to their new location.

Not that I've seen.. Holes created on part faces for example like I suspect the OP is doing in the assembly level move with the face in an ipn tweak..

Seeing that the OP says they have "pretty awful graphics cards" just makes me lean towards that being the problem.

Blair,

   That's not true. See the "Don't Disappear" image. The "disappear" image is what's concerning. This holes will not only turn on/off in the IDW, but also in the IAM.

Our graphics card is NVIDIA Quadro 4000.

Seem to remember quite a few people having problems with those around here..

I'd try to update the driver first.. As its a quadro you "might" want to check the "Autodesk Inventor certified driver list"... But that wouldn't stop me at all from trying the latest from the manufacturers site.

I wonder if the part that's being suppressed is the surface that's being used/referenced for the holes and Inventor is loosing it's way. Check that you are current on all SP's, Updates and Hot-Fixes for your version of Inventor as well.
