I had a lot of problems with weldments in SW2009SP4.  Basically incorrect angles, angles not showing etc.

The issue came up as resolved the last time I checked it, but no service pack was given.  I updated to SP5 and it seemed better.

Now I'm on 5.1 and those familiar issues came back.  A simple table model comes up blank on mirrored weldments, on some lengths work but not angles, on others all properties are missing and properties which show in the cut list folders don't propogate into the drawing cut-list.

The problem occurs when parts are combined after mirroring.  This used to work, why doesn't it now?  Mirroring is a large part of weldments as most frames have at least one plane of symmetry.

SW2009 has been out for well over 18 months.  How long does solidworks expect us to wait for them to fix the tools we paid good money for?
