Feature contains overlapping solids

I am currently attempting to fix a bearing in SW, but it is so screwed up that I don't know what to do. Every time I try to edit the features (any feature), I get the message that "Direct edit not possible. Part contains overlapping solids." I don't know what to do, how can I fix this? The whole point of me trying to edit it is to remove the overlap, but because of the problem, it seems I can't fix the problem. Any ideas? I would post the part, but due to confidintiality agreements, I'm not allowed. Thanks in advance for any help you may be able to give!

Drew,

Would it just be easier to start over? A bearing isn't a very complex model, generally speaking.

You cannot edit features, sketches, etc in imported models because there aren't any. IGES, STEP and the other application-neutral data-exchange formats don't support this. If you can get a Parasolid file (.x_t, .x_b) from your external company, there is a better chance of their data coming through as intended but there'll still be no feature, sketch, etc data. Only if your external company is using Solidworks can you get to their source data.

The only other method is to use Featureworks. Can't remember whether this is available in Basic Solidworks (I use Premium) but this is the way to edit and/or recognise features that can then be edited. Here's the Featuresworks help link if you need it http://help.solidworks.com/2010/English/solidworks/fworks/legacyhelp/featureworks/fworks/overview_of_featureworks

  Robert,
  
  I don't know what makes you think this is an imported model, but I don't get the feeling that it is.
  
  Drew,
  
  Can you roll back in the model tree? Can you right click on a sketch and edit it? What other things have you tried?

    I've tried rolling back the tree, and then it tells me that part of the model is in a rollback state and I can't edit anything. I don't believe that the model was imported, rather, it was created by a former employee that I've been cleaning up after for a while now. I've run into issues like this several times, and it's beginning to get frustrating.

        I'm beginning to think I may have to. The more I mess with this the more frustrated with it I get.

        Sometimes it is easier to start clean than to try and diagnose and fix a bunch of bad modeling.

  Robert, I'm running SW 2014 Premium as well. I appreciate the advice, and I apologize for wasting your time by not adding that it wasn't an imported file.

Maybe use Delete Bodies to temporarily get other bodies out of the way.

Maybe export the offending bodies separately, edit, and reimport.

Drew, I know you can't post the part, but can you post a screen shot of the part?
Honestly, without seeing what geometry is causing the fault and without knowing what command you're trying to use for direct editing, there isn't much that can be done.

  Just looked over my contract. I'm barred from posting photos as well. I'm sorry, I wish I could be of more help.
  
  The bearing is an angled roller bearing, When it was created, somehow the rollers became embedded into the outer race and left a gap above the inner race. The rollers are also embedded into the outer edges of both races.

    If you're getting the "rollback state" message, that tells me this is an assembly, not a part. Is this assumption true? If your rollers being embedded in the races sounds like it may be some mating issues. Could be, too, that the roller parts need to have their size adjusted, which you can/should do at the part level.
    While I realize you can't post the part or a picture of it, can you post a picture of just the tree?

      I just junked it and started over. It is turning into much more of a headache than a simple bearing is worth. I appreciate the help though. It was just a part, but a 20 body part, that was modeled horribly to begin with. Now I know why the former employee who did this is former.
