About the last error, (entnext (entlast)) is always nil, so (entprev nil) ends with an error as it should be. But you are right again, I should catch this error and print a message instead.
It depends where our entity supplied to function is situated...
It depends where our entity supplied to function is situated...
You are missing the point - the code is painfully inefficient regardless of the position of the supplied entity in the drawing database.
Think about how the while loop is being evaluated: the code is retrieving a new selection set of all objects in an entire drawing layout every time the index variable is incremented.
Your code is doing the following:
Iterate over the drawing database to retrieve a selection set of all objects in a drawing layout
Query the entity at index 0
Iterate over the drawing database to retrieve a selection set of all objects in a drawing layout
Query the entity at index 1
Iterate over the drawing database to retrieve a selection set of all objects in a drawing layout
....
No, Stefan (entnext (entlast)) if (entlast) is polyline entity is very next nested entity to parent (entlast)... In my case where (entlast) is polyline (entnext (entlast)) = VERTEX entity...

...(ssget "_X") make a selection of all entities in all layout:
now i see, thanks. but in this case (entnext (entprev e)) will not be equal to e
and more (ssget "_X") will iterate through all entities on all layouts
Command: (setq kkkk (ssget "_X"))
<Selection set: b2>
(sslength kkkk)
Marco.-OK Louis, I'm sorry I did not realize... read below...
The entPreviousFrom it is an autolisp function and accepts one argument - what do you mean by that accept argument?.
Where: <ename> normal or nested
Usage: (entPreviousFrom <ename>)

Try my new test DWG and put a counter inside your function:Command: (sslength kkkk)(ssget "_X") returns entities in the following order:
2396

Select the red line on magenta rectangle, is the (entlast) in model space,

I think we might be talking in circles. The OP was about a function which operates in reverse from what entnext does.Do you think that there is, at this time, a function that meets these three points?
So:
- If supplied argument = nil (unfortunately ALisp doesn't allow for optional arguments in defuns), then get entlast (instead of the 1st entity in the DWG)
- If supplied argument is an ename of an enetity contained either in the Model Space or any Paper Space then get the previous entity
- That could be a joined entity like an attribute, not to be confused with nested entities like lines inside blocks.
- Note entnext runs along all entities in MS/PS1/PS2 ... PSn as if they're all contained in one group (not each separately).
- If the argument is an entity nested inside a complex entity like a block definition, then get the previous entity inside that block - stop at the block record itself.
Hi Marco,Grazie a te, spero di ritrovarti ancora.
Thank you a lot for taking the time to run the tests and doing the benchmarking.... for me I guess it is all about my contribution on this thread, was fun but I do not use autolisp nor I work with objectarx anymore or even use AutoCAD nowadays. My sample code is there open, so anyone can use it and update it and make it better!!!.
Have fun!
:)
Select the red line on magenta rectangle, is the (entlast) in model space,ssget generates selections set in a reversed order i.e. entlast is the first element. and still your function is iterating 2814 times. why? because it searches though all layouts.

entnext starts from the beginning and steps through all vertexes but doesn't go into layouts.I think entnext steps through all entities (DWG with only 3 entities):
(defun VK_entprev1 (e / e1 e2 Countr)
(setq Countr 0)
(setq e1 (entnext))
(while (and e1 (not (eq e (setq e2 (entnext e1)))))
(setq e1 e2 Countr (1+ Countr))
(princ "\n ") (princ (entget e2) )
)
(list e1 Countr)

draw an arc
draw a text
then inspect (ssname "_X") in vlide

Gracias a ti, espero encontrarte de nuevo. :kewl:
Sorry new to this thread, but I would naturally assume ssget would select items in the same order as the draw order in ACAD essentially by their order in the DB. So not only would it be dependent on when they where created but also edited or modified,OK
you could also manipulate the order with the "draw order" command.

Thats not the point... (entnext) won't work with (car (nentsel))... The function (entprev) should perform exactly the opposite than (entnext)... So (VovKa-MR-entprev) is correct function...

anyway i suggest using this variant http://www.theswamp.org/index.php?topic=45732.msg508956#msg508956 (http://www.theswamp.org/index.php?topic=45732.msg508956#msg508956)
it's faster and works within nested objects if the argument supplied is a part of a complex entity

Regularly (entnext <block entity>) won't step inside that <block entity> and find very next nested entity... Only if (entnext <nested entity>) if will find next nested entity...entprev works the same way
Grazie Marco, so che sarà difficile non partecipare...Hi Marco,Grazie a te, spero di ritrovarti ancora.
Thank you a lot for taking the time to run the tests and doing the benchmarking.... for me I guess it is all about my contribution on this thread, was fun but I do not use autolisp nor I work with objectarx anymore or even use AutoCAD nowadays. My sample code is there open, so anyone can use it and update it and make it better!!!.
Have fun!
:)
Gracias a ti, espero encontrarte de nuevo. :kewl:
entprev works the same way
the main condition for entprev function is (eq (entnext (entprev e)) e)
No, VovKa, if I select with (car (nentsel)) second - next nested entity in block that contains more nested entities, (entprev) won't give that previous nested entity, but if I select that previous - first nested entity with (car (nentsel)), (entnext) returns second nested entity I previously picked... So (entnext) works in space of that block, but (entprev) can't enter that space, because (entnext <parent entity>) returns entity in space of parent entities and this is how (entprev) works, using only parent space...i think i can not fully understand your explanation.
(while (setq e (car (nentsel)))
(princ (if (eq (entnext (entprev e)) e)
"ok"
"error"
)
)
)

Selection sets may be influenced by the Layouts, I don't truly know, but that's not the point of this thread is it?perhaps this thread may be interesting:
But I do know that entnext and entlast is not affected by them at all.

...and where is "TEXT on Layout2"?:? oops yes, you're correct! Only the last opened PS tab is iterated by entnext. So it's a situation of the model space object and the current paper space object.

"If entnext is called with no arguments, it returns the entity name of the first nondeleted entity in the database.Ah! But that's then not strictly true is it? E.g. blank drawing (all VP's deleted) with a circle on Layout2 with Layout1 open. (entnext) will give you the "Viewport" which is actually Layout1's page. But if you later draw a line in model space - that is considered the "1st" (not the VP, nor the circle).

But if you later draw a line in model space - that is considered the "1st" (not the VP, nor the circle).
Thus it should rather read as: "If entnext is called with no arguments, it returns the entity name of the first nondeleted entity in either the model space or the current paperspace. If none found in model space, then the paperspace page (not viewport) is the 1st found. If the MS was blank before drawing anything in any PS, then any later entities in MS will be considered prior to the existing entities in the PS. Only after MS contains something is the order of entities constant. If you then delete the MS contents, the VP of PS becomes the 1st entity - even if you then draw something new in MS. When you then swap to a different PS the MS items are interpreted as previous to anything on the new PS (even if they were drawn earlier)"
It seems these edge cases might need lots of checks to get entprev working as an exact inverse of entnext.
Here it is my latest code:Sorry for late:

Let's see if works (arx attached).
TODO: Next task need to study AcDbDimension(s)... and being able to do the scan back.....the seek() works on the iterator but somehow the step back or something is not working... hmm need to install the arx wizard right since the debug does not work and can't step into each line..... :(

Marc' I think your version has even advantage in comparison to (entprev) my last version I posted... The only difference I see in obraining result is the case where you actually pick with (ale_entprevious (car (nentsel))) first nested entity in block - it then returns "BLOCK" entity - BlockBegin... And my version (entprev (car (nentsel))) with picked first nested entity returns nil - similar to picking last nested entity inside block or dimension with (entnext (car (nentsel)))... I've checked the cases with paper/model space entities and both version act the same (so I don't know how did you get these results stated in post 109) :

Thanks, Luis for your tests, it was really small issue - I should have added SEQEND entity to (wcmatch) function... So I think that should fix it... Maybe I missed something else? Who knows, please inform me again if you find something strange like this issue...
M.R.
usage:
(EntPreviousFrom <ename> <container ename optional>)
returns: previous ename or nil or first ename on space
(setq e (car (nentsel)))
(setq e (EntPreviousFrom e))
or...
(setq e (car (entsel)))
(setq e (EntPreviousFrom e))
or...
(setq data (nentsel))
(setq e (EntPreviousFrom (car data) (car (last data))))
Marko,
I tried and still does the same - will give a try tomorrow. Thanks!
@Marko: your entpreMR seems ok, I have seen the problem with my ALE_EntPrevious and XREF, I'll see if I can solve. Thank you.
@Louis: do you know how do we get the same result of (ssget "_X"), equal to what you see in this window?
Hi Marc'Antonio,
Sorry, I do not understand your question, do you want to use some other function to get the same as using SSGET _X ? or if there is another way to get the same? and in that order?
edit: I see that image capture is taking from the VLIDE under View -> Browse drawing database -> Browse all entities
Here it is 5:30AM - I know in Italy it is 2:30PM --- let me get my first coffee.
Luis.
Yes. Take the coffee first!
My question: (ssget "_X") is very slow, is there another method in Visuallisp to obtain the same result?
That is a list of just main entities as can be seen also in Browse drawing database -> Browse all entities?
Ciao.

To add something into my previous post, maybe something like this?I do not know if your code "...(setq ms (vla-get-modelspace db))..." is faster then (ssget "_X") because I have to iterate on ModelSpace and all layouts...Code - Auto/Visual Lisp: [Select]

Thanks Lee, I thought (exit) or (quit) but the idea of putting it in a (vl-catch-all-apply ...) I would never come!I need a method to stop (vlax-for ObjFor (vla-get-block LayFor) ...

Marc', can you benchmark also this version... I think it's more optimized for entities near end of ss (ssname (ssget "_X") 0) or (entlast)... It would be nice to see if this version is actually faster than orig. (entprevMR)...Marko, I am doing tests, (ssget "_X") is very slow, this version use a selset as argument:
