Imported IGES assembly with parts that cannot be recalled...

Here is what I sent to my VAR last week as you suggested recently:

A couple guys at work here with myself included have been having a hard time importing files from our customers as of late.

The long and the short of it is this:

We import a file (.step for instance) and all seems to go according to plan (pic 1). Although everything loads lightweight, I can rotate, show/hide, etc.

But after saving the top level assembly after import, when I go to open an individual part from the feature tree, for instance the top one in the tree (pic 2) I get that annoying error. And it persists for each and every part thereafter.

And what makes it worse, is that after that error, those parts disappear from the screen, almost as if the file doesn’t exist for the geometry. (pic 3)

A similar issue arises when you are dealing with a sub-assembly within an assembly. Everything looks good on the screen, even in pic 4 where everything appears to be resolved.

But when you attempt to open one of the imported sub-assemblies, everything goes awry. (pic 5)

For every file that is referenced in that sub-assembly and even in child sub-assemblies, you get a separate error message stating the same thing, shown there in pic 5.

And again, when the error messages finally disappear, nothing is left in terms of the original geometry. (pic 6)

Once every 4-5 times or so, SolidWorks actually hard crashes, and closes completely after failing.

I am wondering why we have never had these issues in the past when importing files into SolidWorks.

I have tried importing on multiple computers with multiple files, and as of late we have had terrible luck and encountered these two errors on numerous occasions.
