I feel stupid for asking because Ive used SW for along time and have seen this message before but after doing so research on the Internet and my SW Bible I have yet to get the answer Im looking for. I opened an assembly that has an assembly in it and I had errors that told me to edit definition in the assembly that is referenced in this assembly. I opened that assembly and there are no errors. I checked all the parts and there are no error's. So could some please define exactly what I need to look for when i see this error. Thanks

Edit Definition ? Hate to ask but.....
Got the old needle in the haystack hunt, huh?

In the top level assembly, are any of the sub assemblies set to flexible?

Not sure now becase I got frustrated when I could not find any errors that I deleted the assembly and inserted again and re-mated. All is fine now. Did not have any luck with SW's help menu or Solidworks Bible 2007. Is this one of these you should know subjects that nobody writes about?

Funny, I had the same thing happen yesterday. As far as I could tell the sub asm was error free. I also had no flexible asm's in my top level asm, everything was mated and rigid.
I did the same thing, deleted and remated. No problems for the rest of the day and today so far. Maybe it was (not to bring up another thread or merge the two but) a lightweight issue? Was your sub asm lightweight? I do not remeber myself if mine was.

Well, w/o screenshots of the assembly or the assembly itself, it's pretty hard to troubleshoot exactly what your problem was. 'Edit defintion in assembly' doesn't really ring a bell with me, but I've had problems in top level asm with subs that are set to flexible causing problems in the top level asm only. Glad you got it working!

Re: Edit Definition ? Hate to ask but.....

It's been a while since you asked for a screenshot, but this was the only discussion I found about the issue. The assembly was ok yesterday. Opened it today and got an error. I have not changed anything since yesterday when I saved it before going home. First pic is the notification from SW. Second picture is from assembly, where it shows the part in red and third pic is when I open the part, it does not show red.

Oh and got it fixed right away. I opened up the part, opened up last sketch to edit, exit sketch, save part and back to assembly. Error was gone.

I can confirm that just editing a sketch will remove this error. Thx for the tip, it was driving me mad.


This I can say usually happens when you let solidworks create new subassemblies automatically. Especially if you have external references in your sketches.
