two questions

Hi I would like to know if you can automatically answer the following two questions ...

How to get the total length of lines or layers differentiated by style.

By using acadiso.lin I have created various styles of lines, the idea would be to know the total length of each custom line existing in a drawing.

How to know the number of blocks that are in a drawing automatically. Would I know the amount automatically if I remove or copy a block?

Is there any way to find this out if it is not possible to do this automatically?

Re: Block count. Have you looked at the BCOUNT command in Express Tools?

BCOUNT

Counts, itemizes, and displays in tabular form, the number of insertions of each block in the selected objects or in the entire drawing.

By the way, it is not necessary, nor is it recommended that forum members double post. It just confuses things down the road. Thanks.

for the 1st question you could try

http://www.cadtutor.net/forum/showthread.php?42734-Line-Length-Calculator

and 2nd, does the BCOUNT command not do this already? it gives the name and quantity of that block in the drawing and the total amount of blocks altogether in the drawing

For the line lengths, I'd try something like this:

OK..now we have two threads with the exact same question going which is what we try to avoid here.

migs: I suggested BCOUNT in the other post by the OP.

Ok, sorry.

I know the command Bcount, but my question is whether it is possible to count blocks automatically, either by using a table, Reactor, etc..

Here is mine for counting Blocks in a drawing , I have just made it for you.

(defun c:THblk (/ ss ents) 
;Tharwat 09.Septmber.2010  
(if
 (and
   (setq ss
       (ssget "_x" '((0 . "INSERT"))
	)) 
           (setq ents (sslength ss)))	        
 (if
    (cond (
     (= ents 1)
        (alert (strcat " You have only" " " (itoa ents) " " " Block ...")
	       )
    )
            (
	     (> ents 1)
	     (alert (strcat " You have" " " (itoa ents) " " " Blocks ..."))
	     )
   )
   (princ)
   )	
   (alert " *** NO BLOCKS FOUND *** ")
 )
 (princ)
 )
 

Regards,

Tharwat

ReMark: I never noticed your other post regarding the BCOUNT command or else i would have referred him there instead

Well it looks like this will become the defacto main post so I guess my argument is mute. My apologies.

I merged the two threads into this one.

Titoprax, please post a question only once.

Search for Upgraded BCount, and Line Length Calculator, I believe someone has already provided a link for the latter.
