DefaultTextFontAutoCAD

This variable represents the default AutoCAD text style and refers to the style defined in DefaultTextFontMe10. There are 3 text styles available for conversion. If the two settings are:

DefaultTextFontAutoCAD=ROMANS
DefaultTextFontMe10=hp_i3098_v

this means that all texts defined in ME10 with the style "hp_i3098_v" will be converted in AutoCAD using the "ROMANS" style, and vice versa.
