This doesn't happen everytime, but quite a bit.  I'll make a drawing of a sheet metal part including a view of the flat pattern (I always pull the veiw out of the view pallet), I'll have all my dimensions laid out, save and close.  When I open the file to review it, I get an error message saying that SolidWorks cannot find the flat pattern configuration, then I recheck the "flat pattern view" option in the view manager and the flat pattern reappears, but blows all my dimensions away.

Does anyone know why this happens and how to prevent it?

Thanks in advance.
