      <description>&lt;P&gt;Is there a way to set up text for rectangular duct throat lengths and radius&amp;nbsp;elbows rather than having to&amp;nbsp;manually&amp;nbsp;input them?&lt;/P&gt;</description>

      <description>Use a mix of DIMSTYLE and ENHANCED ATTRIBUTES in a block. Sometimes I layout ducts for monitoring systems because of airflow, but I do it in 2D. If you want a sample of how I do it, I can extract a small sample for you &lt;img class="lia-deferred-image lia-image-emoji" src="https://forums.autodesk.com/html/@38DF24EF580240D512020314976B5FC8/emoticons/1f642.png" alt=":cara_con_una_leve_sonrisa:" title=":cara_con_una_leve_sonrisa:" /&gt;</description>

      <description>&lt;P&gt;It looks likely you are not using any ducting add-on.&lt;/P&gt;&lt;P&gt;Theoretically speaking, there are 2 ways to get text/size of throat:&lt;/P&gt;&lt;P&gt;1) Measure the line lengths&amp;nbsp;on&amp;nbsp;an existing duct object then&amp;nbsp;place&amp;nbsp;text that matching what you got;&lt;/P&gt;&lt;P&gt;2) Draw new duct piece then obtain the throat size from your input of the duct.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;If I understand your question correctly, you are after the 1st option.&lt;/P&gt;&lt;P&gt;Here is an example:&lt;/P&gt;&lt;PRE&gt;(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&lt;/PRE&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Note: This code measures lines only, not polylines.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;HTH&lt;/P&gt;</description>

      <description>&lt;P&gt;1) Copy my code to NotePad then save it as &lt;FONT color="#ff0000"&gt;ThroatSize.&lt;STRONG&gt;lsp&lt;/STRONG&gt;&lt;/FONT&gt;&lt;/P&gt;&lt;P&gt;2) Move this file to&lt;/P&gt;&lt;P&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; C:\USERS\YourName\APPDATA\ROAMING\AUTODESK\AUTOCAD MECHANICAL 2014\R19.1\ENU\ACADM&lt;/P&gt;&lt;P&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; (Note: Your AutoCAD version may be different to mine but the path should be very similar.)&lt;/P&gt;&lt;P&gt;3) In AutoCAD Click "Load Application..." under "Tools" tab (or type &lt;FONT color="#ff0000"&gt;_appload&lt;/FONT&gt; in command line),&amp;nbsp;after Selecting&amp;nbsp;&lt;FONT color="#ff0000"&gt;ThroatSize.&lt;/FONT&gt;&lt;STRONG&gt;&lt;FONT color="#ff0000"&gt;lsp&lt;/FONT&gt;&lt;/STRONG&gt; then click "Load" button then "Close".&lt;/P&gt;&lt;P&gt;4) Now you are ready to use the code - type &lt;FONT color="#ff0000"&gt;DuctThroat&lt;/FONT&gt; (not case sensitive) in the command line then click your "Enter" key.&lt;/P&gt;&lt;P&gt;5) Follow the instructions showed in the command line - you should be fine.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;HTH&lt;/P&gt;</description>

      <description>Sorry I was not clear. I could use something like that. I really don't know why it does not have it. It is a common requirement in ductwork construction. I do thank you for your effort. Sent from my Verizon Wireless 4G LTE smartphone</description>
