Within LIFTdesigner 5.4 we have upgraded the DWG libraries to Support DWG 2010 format.Together with this change a client had a problem to export text to Autocad. Even if the export format is DWG 2007 format, that text is not displayed in Autocad.
The reason is that the text is marked as "Annotative". For any reason Autocad rejects blocks with annotative texts inside. Setting the option "Annotativ" to "No" fixes the problem. This problem may also occur within existing DWG files, that worked properly in 5.3.
Solution: Update the existing source DWG files.
