Missing features in part files

So I am a little confused on what happened. I opened an assembly today and I got a bunch of messages saying that the internal ID of a part did not match something(cant remember the message and I am not able to get it to show up again)

well the parts show up on the feature tree, but there is nothing showing in the assembly for the part. When I open up the part files they are blank. There is nothing in it. It looks like it would if I clicked on create new part. The 3 planes are there, but no other features.

I have 32 files like this, all were saved on the same date and at the same time. They all also have a file size of 43kb, so I am pretty sure the data that was there is gone since they used to be larger than that.

I plan on talking with my VAR tomorrow, but just thought I would see if anyone else has experienced the same issue before or knows what causes this.

No one else has this question

John, This sounds like a real bummer. I've never seen anything like that. Good luck.

  I can understand one part getting Boogaard up, but over 30 that were in the same assembly... that just shouldn't happen.

John,

I don't understand how this kind of thing could happen. One possibility is that SW or Windows just got their knickers in a twist and need to be rebooted.

Can you open the part files up by themselves and see the correct geometry? If so, you can open the 32 files, then open the assembly and save it. That should reestablish the proper connections.

You might also try File/Find References to see if the "bad" files are coming from somewhere unexpected. Check your Tools/Options/System Options/External References. Is "Search file locations for external references" set the way you want it? If you run with it checked, are the right file locations set in Tools/Options/System Options/File Locations/Referenced Documents?

  Haven't figured out what happened yet...
  
  I have rebooted and it did not fix it.
  
  When I open the part files there is nothing there, just the 3 planes, no other features at all.
  
  The assembly is referencing the files it is supposed to.
  
  I did get lucky... the week before I saved a STEP file so I was open to open that up and get the parts I needed, granted they are now just "imported" features so I am not able to easily modify them, but they were all purchased parts that I shouldn't need to modify. So I opened the parts from the step file and saved them as the file names of the bad files and they do show up in the assembly like they should.
  
  It isn't the best resolution, but it works and saves me from modeling up the parts again.

Internal ID's mismatched? Sounds like somebody overwrote your files with empty ones. Any other users on your network? Dig into the file properties and see who created & last saved.

  We have 2 seats of Solidworks. The other guy rarely uses it and if he does, works mostly from his hard drive. My "empty" files were created and last saved by me at the same time. That time is about when I created the STEP file.
  
  I create STEP files all the time and haven't had any problems. No recent hardware or software upgrades. I am remembering seeing another message, not sure when I saw it though, but it was something about the default template not found, would you like to use a blank one?" or something like that.

    Were these perhaps converted or imported parts. I have seen similar behavior after opening an assembly from a STEP Or IGES file from a place where you don't have full access. At first they appears to be there, but don't actually get saved. next time its opened you tend to get empty models.

      Some were converted from Pro/E over a year ago and used in 40-50 other Solidworks assemblies with no issues.
      
      Some were imported, STEP and IGES files sent direct from manufacturer.
      
      Most I modeled myself over the last year or so.
      
      I would assume I have full access as I work from my hard drive. I am basically the only one using Solidworks, and just replicate my files to the network using SyncToy, in case someone else needs to view them.

We have also been experiencing this issue with a couple of files recently. It first started around two weeks ago and luckily we have extensive backups that run on our server multiple times per day and were able to restore old copies of the impacted files without losing much work.

The first time it occurred it was with a model I had been working on in the morning and it was blank after I returned from lunch an hour later and tried to reopen it.

Today, it was a file that was saved 3 months ago back in October and when a coworker tired to open the assembly that it's in, the whole assembly went crazy and had tons of errors. I was able to open it with no problems and was the author of it, but the weird thing is that the file hasn't been saved in months and we have had it open since then without issue.

Any insight into this massive annoyance is greatly appreciated.

Edit: after seeing someone else describe a similar issue in another post, I just remembered that as the file is loading, the part with all of its features will flash on the screen briefly, then it disappears.

  Paul,
  
  to my experience with this happening is that you are opening an .stl document and or are saving to one, and that you are using 2010 seat of solidworks?
  
  if im not correct please tell me and i will try to conjour up a different solution.
  
  Regards,
  Max
