You can tryout the drawing option, def_view_text_height. Here you can set up a larger text height than the other text around, and also, def_view_text_thickness. here you can make the text look thicker than other text around.
Our dtl is setup as write2bush suggest. With the added thickness (def_view_text_thickness) we use .040. The text does not look as nice as "filled" but it does cut down on the time needed to finish drawings
