-open a new CATDrawing document
-write with text command what ever you want
-modify text properties if necessary (bold, font, size, a.s.o.)
-run the CATScript TXT2SKETCH .
-this CATSCript will open also one of the DS CATScripts which you can...

... find it in their on line documentation (I've also attached here a copy -
CAA ...)
-in the new CATPart opened by DS CATScript choose a plane for your new sketch
-right click on mouse and paste (the text is already selected in dwg file in first CATScript)
-don't forget to "clean" the CATPart for unwanted elements (when you paste, a sketch with the name Main View will be also created but there is no problem to delete it).
-take a look in the TXT2SKETCH.CATScript to see which are the paths for CATScripts and dwg file created by the TXT2SKETCH.CATScript.

I know that the final "look" its not so nice, but this is because of the polylines which are coming from conversion of the first CATDrawing to dwg file.

If you want something much nice, you have to explode the polylines in sketch and improve the previous result.
