CREATESYMBOL is an undocumented command in 2012 that might be useful to anyone looking for more symbology options for FDO connected data. This command lets you create symbols from raster files or from blocks in other drawings. You can apply them to any FDO connection type. Try it out, or take a look at http://usa.autodesk.com/getdoc/id=TS16709349 for more details. More info about 2012 to come - have fun!
