I am using SW2011 with SP3.

I am generating a series of drawings of similar parts - sheetmetal parts with a single bend. I have 20 such drawings. I am noticing that when I reopen some of them SW pops an error message that the flat pattern configuration could not be found and it is resorting to using the last known... However, the drawing seems to load correctly.

So just curious what might be causing the error message. The sheet metal part itself definitely has the flat pattern configuration. All the flat pattern stuff is SW generated with default names. The flat pattern configuration is being generated as a derived configuration under the default config.

As an additional bit of info, I have noticed that some of the parts have not flattened out as they should when the flat pattern view is drug into the drawing from the view pallet. They have required opening the part, activating the flat pattern config, untoggling the flatten button, then retoggling. These steps have been outlined in other discussions that I found on this forum.

At this point, I don't have any information to correlate the error message behavior to the manual flattening requirement.

This is not a critical issue since the files are working. Just an annoyance that I would prefer to solve. Any suggestions on where to poke around are appreciated.

Thanks, Daen
