Easy way to do SDF to SHP is import the SDF into a blank dwg creating the OD then export to SHP. There's a few things with SDF that you need to watch with the FDO Bulk copy like int 16/int32 and double types then the nameing of the fields and a few others. You can try FDO to FDO from SL-King.com or Jackie's FDO tool box

Looks like fdo2fdo worked first try. thanks murph! I don't know why ACAD had so many problems this time through. Like I said, I have done this a few times before with success but this time it was no go.
