How to display the total lenght by dyn(F12)?

[Anonymous]

Good morning.I'm from China.I want to ask a question.Thanks in advance and forgive my poor English.

After turning on the dyn(F12), a running total of the distance will display beside the mouse pointer when I use DIST (M) command.

Until now,I only know how to display the text beside the mouse pointer by getXXX function,in the meantime,only grread funtion can obtain the real-time mouse position.But they cannot be used at the same time.

Finally,How the DIST (M) command get the real-time  mouse position information and display it by dyn(F12) beside the mouse pointer .

Can anyone help? Please~~~~~

Hi, both "dist" command and "getdist" function measure the distance between 2 points. They don't measure the total length of a polyline.

Thanks for reply,you can try the way to measure the total length of a polyline that  following the step  1."dist"  2.input a point  3."M" .

Sorry, you're right. I am old school - learned it then never looked back after decade...

Can you show your code here so your question would be better understood?

(defun c:d()
 (vl-cmdf "dist" pause "M")
)

Hey friend,it's the code.But I want to get the point to entmake a lwpolyline.

For example,

(defun c:tt ()
 (setq pt1 (getpoint))
 (setq pt_list '(pt1))
 (command "dist" pt1 "m")
 (while (= 1 (getvar "cmdactive"))
 (command pause)
 (setq pt1(getvar "lastpoint"))
 (setq pt_list (cons pt1 pt_list))
 )
 pt_list
 )

I can get the  pt_list ,but can not get the real-time length.

I only can get the real-time length by the function "grread",but can not display it beside the cross cursor like the "dist" do.

I only want to know how the "dist" make use of dyn mode (F12) to display the message.

I already ask this question in Chinese forum,but nobody know.

HERE from the Lee's code you can pick up the principle.
