It looks likely you are not using any ducting add-on.
Theoretically speaking, there are 2 ways to get text/size of throat:
1) Measure the line lengths on an existing duct object then place text that matching what you got;
2) Draw new duct piece then obtain the throat size from your input of the duct.
If I understand your question correctly, you are after the 1st option.
Here is an example:
(defun c:DuctThroat (/ ThroatLine1 Ent01 ThroatLine1_1stPt ThroatLine1_2ndPt Throat1 ThroatLine2 Ent02 ThroatLine2_1stPt ThroatLine2_2ndPt Throat2 PlaceText) (setq ThroatLine1 (car (entsel "\nSelect 1st line: "))) (setq Ent01 (entget ThroatLine1)) (setq ThroatLine1_1stPt (cdr (assoc 10 Ent01))) (setq ThroatLine1_2ndPt (cdr (assoc 11 Ent01))) (setq Throat1 (distance ThroatLine1_1stPt ThroatLine1_2ndPt)) (setq ThroatLine2 (car (entsel "\nSelect 2nd line: "))) (setq Ent02 (entget ThroatLine1)) (setq ThroatLine2_1stPt (cdr (assoc 10 Ent02))) (setq ThroatLine2_2ndPt (cdr (assoc 11 Ent02))) (setq Throat2 (distance ThroatLine2_1stPt ThroatLine2_2ndPt)) (setq PlaceText (getpoint "\nInsert throat size: ")) (command "._text" PlaceText "" "" (strcat (rtos Throat1 2 0) "x" (rtos Throat2 2 0))) (princ) ); end of defun
Note: This code measures lines only, not polylines.
