Entlast doesn't select the last entity

[3wood]

I drew a line in Model Space first.

Then I switch to Paper Space and drew a circle in Paper Space.

I saved and closed the drawing.

When I reopened the drawing and used (entlast) to find the circle, it actually gave me the line instead. 

How can I use (entlast) find the correct entity?

I attached an example drawing here. Can anyone help me on this issue? Thank you very much.

@3wood ,

Yes your are right...it looks like, when you open a dwg\database (entlast) return the last entity from model space so to answer your question i would step through entities in current layout, this of course if you know which layout you after 😀

Yes, build your own,

or if you would search about this "issue", you will find ready written codes, also in c++/Arx

(Defun whatTheFork (/ ss)
  (setq ss (ssget "X" '((0 . "~VIEWPORT"))))
  (princ (strcat "\nSSGET 0 Index: "
		 (cdr (assoc 0 (entget (ssname ss 0))))
	 )
  )
  (princ
    (strcat "\nEntlast: " (cdr (assoc 0 (entget (Entlast)))))
  )
  (princ)
)

_$ (WHATTHEFORK)
SSGET 0 Index: CIRCLE
Entlast: LINE

Created a "DIMENSION" object (layout1 tab) | Closed the file | Open the file

_$ (WHATTHEFORK)
SSGET 0 Index: DIMENSION
Entlast: LINE

Created a "MTEXT" object (Mode tab) | Closed the file | Open the file
$ (WHATTHEFORK)
SSGET 0 Index: DIMENSION
Entlast: MTEXT

 Perhaps this

(setq ss (ssget "X" (list '(0 . "~VIEWPORT")(cons 410 (getvar 'ctab)))))
(princ (cdr (assoc 0 (entget (ssname ss 0)))))

I am as confused as you are @3wood   😄

Thank you all for the great helps.

(entlast) returns the last entity in Model Space upon drawing opening.

But it doesn't always return the last entity in Model Space or Current Space during the drawing session .

Try following:

Draw a line in MS | Draw a circle in "Layout1" | Draw a rectangle in "Layout2" | Save and Close | Open | Click "Layout1" tab | Click "Model" tab, now (entget (entlast)) returns the circle in Layout1.

I think the best way to find out the last entity in the entire drawing upon opening is using @pbejse 's method, including (entlast) and (ssname (ssget "X" (list '(0 . "~VIEWPORT")(cons 410 (getvar 'ctab)))) 0) to go through Model Space and Paper Spaces and then find out the latest entity from the result.

This is really helpful. Thank you Marko!

I guess (ssget "_L") doesn't return entities on a frozen layer. We may still need (ssget "_X") to get all entities.

Good catch, but you have "LAYTHW" command to thaw all layers and then use (c:elast)... Finally "LAYERP" command to restore layers to prvious state (frozens)...
