Distance between a multiple points on autocad2020?

Are you talking about arc segments, and wanting to know the length along the curve? That can be calculated with some code, or if there is no Polyline width involved, you could EXPLODE the Polyline, look at the length of a resulting Arc [or any segment] in the Properties palette or a LIST command, and re-JOIN the Polyline back together.
If this is not about arc segments, what happens when you use the DIST command?

Hi,
>> DIST do not work anymore between two points!
Sorry, can't agree to that. Command _DIST does wirk between 2 AutoCAD points, as long as you are using the correct object snap.
>> i want to know the distance between different points
>> of my polyline which is not straight
Well, that sounds totally different to your first post, there was no message about a polyline-length between 2 points on the polyline.
What would I do without having a tool: copy the polyline, run command _BREAK on both points you like to have as start- and endpoint for measuring, then select this new polyline and use either property window or command _LIST to get it's length.

It is not an arc unfortunatelly! when i use DIST I select for example a ligne and it gives me "the lenght (read only) "of it.
I don't understand. The DIST command does not ask you to select objects. It does this kind of thing:
Command: DIST
Specify first point: {I picked a point}
Specify second point or [Multiple points]: {I picked another point}
Distance = 0'-2 95/256", Angle in XY Plane = 288d26'5.82", Angle from XY Plane = 0d0'0.00"
Delta X = 0'-0 3/4", Delta Y = -0'-2 1/4", Delta Z = 0'-0"
[That's in Acad2019, so maybe 2020 is a little different.] If that's not what you are asked for, run the command, press F2, and copy the command-line contents and paste them into a reply.
A listing of VLA properties would include the (RO) read-only indicator on the length of a Line. Maybe QuickProperties about a Line in 2020 also does, but not in 2019. How are you really getting that?

Going back to that.... Maybe you need something like this:
(vl-load-com)
(defun C:DPO ; = Distance between Points on Object
(/ ent p1 p2)
(setq
ent (car (entsel "\nSelect object: "))
p1 (getpoint "\nFirst point on object: ")
p2 (getpoint "\nSecond point on object: ")
); setq
(prompt
(strcat
"\nDistance along object between those two points = "
(rtos ; in current Units mode/precision settings
(abs
(-
(vlax-curve-getDistAtPoint ent (vlax-curve-getClosestPointTo ent p1))
(vlax-curve-getDistAtPoint ent (vlax-curve-getClosestPointTo ent p2))
); -
); abs
); rtos
); strcat
); prompt
(princ)
); defun
You select an object, and select any two locations along it, and it tells you the distance along that object between those two locations. It works on any kind of object with linearity [Line, Arc, Circle, Polyline, Ellipse, Spline, Ray, Xline].
It asks for the points to measure between separately from selection of the object. It could be altered to use the point at which you first select the object for the first point of the measured distance, if that would suit your workflow better.
It's in very simplest terms, and does not check that you picked an object that it can measure along [i.e. not a thing without linearity such as Text or a Block], nor that the two points you pick are actually on it. But it could be enhanced to check for those things.

You are typing DISTANCEWhere did you come up with that at? ....
I had the same question. I assume he's inferring it from Message 10, because when you type DISTANCE, its report on the System Variable value includes the "(read only)" part mentioned there. But the OP mentions using DIST [4 characters only] there, which is why I said I didn't understand in Message 15. So, @Anonymous, what command or System Variable name are you really using?
