I had almost forgotten about this issue. I have since run into a similar issue with trying to get the scale of a drawing and using that to change text on a scale bar.
The problem is, as F. Beister mentioned in the related thread, the autotext command is substituted in the 2D environment, not in the GDL script. So until AC has to display the text, it remains as <DRAWING_SCALE>. Trying to manipulate it, e.g removing the first two characters of 1:100, results in RAWING_SCALE> being displayed.
Ultimately it seems the best solution would be to create request functions for all of the auto text features, similar to labels requesting attributes of the elements they are attached to. This would allow use in 3D and for the text to be manipulated for other uses.
