when i use dimension annotative style, with your lisp , my viewport is value, but dim not display. it appear only i click viewport toolbar. Why, i dont understand. What way fit ? ( ex.: i use dim annotative 1/50. it display only in viewport 1/50.BUt i use your lisp with 1/50 viewport, viewport change into 1/50 without dim. it only display when i click viewport toolbar 1/50 )
