Select blocks with different names at the same time

[luigiverdenico]

Hi all,

I have a format drawing where there are hundreds of blocks with different names.

Starting from this drawing, I have to leave just some dozens of these blocks (whose names are in an excel file), deleting others. My question is if it is possible to automate the operation through a command like "quick select" or a lisp able to select simultaneously unnecessary blocks (as an exclusion of the necessary ones shown in the excel file) so as to delete them quickly?

Use this piece of lisp code :

(setq ss (ssget  '((0 . "insert")(2 . "block1,block2,block3"))))
(sssetfirst nil ss)

Probably easy to do with Excel

"block1,

block2,

block3"

Hi,

>>My question is if it is possible to automate the operation 

till you find one ... i suggest to start now with QSELECT or SELECTSIMILAR command. 

Regards,

(setq ss (ssget  '((0 . "insert")(-4 . "<NOT")(2 . "1,2,3")(-4 . "NOT>"))))
(sssetfirst nil ss)

Reversed, with the parameter NOT to exclude instead of including.

First of all thank you for the help. If I understand correctly, what you have reported is a part of the lisp code. Unfortunately I don't know about lisp so I can't complete it. Can you send me the complete file (you can call the  command "abaco"). Thank you.

Since you don't know lisp - the other suggestion that was made should work well.

Click one of the blocks you want to erase (or several different if you wish) then right click and choose the select similar command. This will select all what that name (* options for this command may be different and not do this - but default mode does).  You can then just hit delete on the keyboard, or use the erase command.

It may take several uses of the command to get them all - but it's a sight easier than typing in all the names you wanted in a list.

What type of blocks they are - dynamic or not?

IF your block are non-dynamic, use suggested LISP lines (below little simplified). There is really nothing to complete, just replace the dummy name with the real once delimited by comma and copy-paste the line into the command-line. That's all. As simple as it sounds, no more code needed.

Positive match:

(sssetfirst nil (ssget "_X" '((0 . "insert") (2 . "block1,block2,block3"))))

Negative match:

(sssetfirst nil (ssget "_X" '((0 . "insert")(-4 . "<NOT")(2 . "block1,block2,block3")(-4 . "NOT>"))))

If your blocks are dynamic, then a code has to be more advanced.
