Text styles
When you activate the option Default settings in the Dialog box ATHENA options, ATHENA loads the text styles in new drawings from the file ATHENA\DATALOCAL\ath_txt.dex. This is the library file containing the text styles.
The ASCII file ath_stil.def from earlier ATHENA versions is no longer used. For reasons of compatibility though it is converted during the program start into an ath_stil.dex if the file ath_txt.dex has not been found.
Note 
If ATHENA is installed in a network, you can move the library file ath_txt.dex into the DATAGROUP folder to ensure that all ATHENA users in the network use the same text styles.
Use the AutoCAD command _style to create and change text styles. You will find further information in the AutoCAD documentation.
Use the command Managing text styles to manage text styles of the drawing or of the library.
