AutoCAD Visual LISP / AutoLISP :: Script To Change Duplicate Tag Names And Their Values?
Jun 17, 2012
I need to change the value of some tags in a title block on multiple drawings. I tried using Lee Macs attribute changer [URL]. It works fine but not when tags have the same name.
I then looked at this code - [URL]
Idea was to change the tag names then use Lee Macs program. It too fails when there are duplicate tag names. It changes all tags not just the one I want.
In the the title block I have 3 tags with the name "NAME" but only one will have the value I'm looking to change. If I could place an IF statement some where in the above codes (or another code altogether) to instruct that IF the tag name is "NAME" with value "Dennis (BSL)" then change either the tag name or the value to "Daniel"
Im pretty bad at this programming stuff but with so many drawings I need a easier, automated way of doing this.
I have an attribute blocks and this att block has two tag values , is there a simple code for to change 1st tag values automaticly according to 2nd values ?
for example :
1st tag (50x50) - 2nd tag ( 100 ) ==> 50x50-100
if i enter 201 valuse to 2nd tag then 1 st tag has to change as 100x100
if i enter 501 valuse to 2nd tag then 1 st tag has to change as 150x510
I have 2000+ drawings that have either the layer state "LMAN_DWF" or "DWF". I want all of them to read "DWF" for scripting purposes. LSIP routine that will go into a drawing and change rename a layerstate if it is named incorreclty, but do nothing if it is named correctly?
Does Layer State "DWF" exist?
If Yes, skip file and move on to next file
If No, does Layer State "LMAN_DWF" exist?
if Yes Rename Layer State to "DWF"
If No, skip file and move to next file.
Or a LSIP routine that can simply dump a list of all drawings in a directory that contain "LMAN_DWF" as a layer state. I could then use that list to do a simple script to change the layer state names on those specific files.
This is a routine that draws a line between duplicate text.
Would it be possible to have the line as bold red p-line so that its easier to identify.
;; This AutoLISP routine examines all the user-selected TEXT and MTEXT items, ;; and draws a line on the current layer between any two that have identical ;; string values. ;; Leading and trailing blanks spaces are ignored. ;; %% modifiers, like %%u, are not ignored. ;; Upper- and lower-case differences are not ignored.
(defun c:fdt () ;;Find Duplicate Text
(prompt "Select text items to examine: ") (setq ss (ssget '((-4 . "<OR") (0 . "TEXT") (0 . "MTEXT") (-4 . "OR>"))))
How to write some code which could create variable names like var1, var2, var3, etc. I need to do this because I have a large number to create and the actual number is variable and unknown.
Instead of manually writing a large number of line like
(setq var1 value1) (setq var2 value2) etc
I used to be able to put 1 line in a loop to create and assign a large number of variables. I remember that it involved the use of the set (not setq) and read functions.
What I was thinking of was in a loop some times I need multiple sets of similar variables but am not sure how many sets I am going to need. I would like to be able to increment the variable names each time the loop runs.
Say I have a block that contains two attributes, one contains a value that is a number and another contains a value that is letters. I have many of these blocks placed in a drawing, could you create a lisp that would return the sum of the number value and return it to the command line along with the letter value. Something like this:
A plugging we use has just updated and loading double menus causing error messages prompting that menu already exists unable to load.
In my cui the menus are loaded in my enterprise as well as my main.
How do I keep the menu with the same name in my enterprise yet unload the one of the same name in my main (where it shouldn’t be) using lisp (I want to Automate this using lisp, since I'm not always in office at the same time as everyone else)?
Any routine where I could keep picking on my exit arrow blocks (showing how many persons exiting from each space) one-by-one and the program would add up the numbers. For example I pick on blocks with numbers of 2, 4 & 3 and I would get 9.
We are using a title block and it has an attribute field that links to the file name. Now one of our projects is adding the revision to the CAD file name, but it messes up our drawing sheets.
i.e. It was fine when the CAD file name was 111-A222-ZZ-X-123456.dwg and this would display the complete 111-A222-ZZ-X-123456 in the drawing title.
Now we need to do this, the CAD file name, 111-A222-ZZ-X-123456-001002-A1.dwg and we still need to just show 111-A222-ZZ-X-123456 in the title block, striping away the 001002-A1.
I have a parent directory with x-amount of folders contained inside. I say X-amount because I would like to keep adding or deleting folders as time progresses. I want the folders contained within this parent directory do be read into a lisp variable and then be printed to the command prompt till every folder is displayed by name, then the loop may stop.
I need to wright a routine in autolisp that selects all 3Dpolylines with the same vertex Z value.Qselect as no transparent mode and filter doesn't work.
I have a block named "WIDGET-A". And in that block are (4) attribute tags whose names are:
"ID" "TAG01" "TAG02" "TAG03"
The user will be prompted to pick the value displayed at any of the "TAG##" attributes - they will select the attribute tag they want (we don't know which one it is, we just want to assign that value of the attribute tag they clicked on to a variable called "VAR2".
Now, what we also want AutoCAD to evaluate, behind the scenes, is the value of the attribute tag named "ID" which we know always exists in the block and then assign that value to a variable called "VAR1".
Is there a way for AutoCAD to do this all from only a single user pick on top of an attribute value, in a block whose name isn't always going to be 'WIDGET-A' either.... But the block, whatever it's name, will always have the attribute tag "ID" with a value in it, and we always want to capture the value of whatever attribute tag within the block that the user clicked on.
This time I'm wrestling with getting the values from multiple blocks. The blocks all have the same name but at least the attributes have names this time. Each block have exactly 4 attributes, like: att1 (a number representing chronological order), att2 (some data), att3 (the actual date as a string of when the data was added), att4 (some more data)
I need to get and store the attribute's values. I was hoping to make a selectionset of the blocks and step through using the chronological order number.
At this point I have tried several combinations of foreach and ssget "x" (list (cons 2 MYBLOCK)), but I keep getting errors that I'm sure are telling me that I'm not passing the correct information to the function for iterating through. I'm banging my head.
I often have DXF files that contain very many short (10 digits or less) instances of text, and only a few long instances of text (11 digits or more)....
I would like to use AutoLISP to delete all of the short text in my DXF file, but leave the longer text.
I need a lisp sub-function that can empty all attributes of a specified dynamic block. The idea being that the specified block contains data that changes often and in order to repopulate the block's attributes with new data to replace the old I wish to just blank out the old data first, because it's possible that the new data may not utilize as many attributes and all of the old data must be removed.
The thing is the block I'm after is on several layouts, CTABs and they all need to be wiped clean.
I have an interesting challenge. I am tasked with updating old drawings. The only difficulty that I've run into with the old files are that the TitleBlocks are all done with all of the attributes are named "SPEC". There are 90 attributes. I'm really struggling with getting each attribute's value and then storing the value to a variable so that I can then put that value into a new TitleBlock. The old TB will be deleted to avoid future confusion in the file.
(To clearify, the old TitleBlock is in model space, while there are actually nine new TitleBlocks all in seperate paper space Layouts, and this program may have to run on hundreds of files.)
getting the values from the Old TB. I need them in order of first to last or last to first (either way will work since I have the variable names in a list that can be reversed if necessary.)
simple function to read through the block's attributes in order and store the attribute's value to a variable name in the seperate list (also in order)?
lisp routine that will add together the values of text entities? For instance, if I have a big parking lot and each section is labeled with the number of spaces, I could pick the texts and it would add all the numbers together to give me a total. Right now I export to excel to do this. I have quite a few situations where this would be handy, not just for parking spaces, so I really just want a lisp that will add all my selected numbers.
How to connect to MySQL database and insert data from a set of blocks containing attributes?
Something like:
block 1:
- x coordinate; - y coordinate; - handle;
block 2:
- x coordinate; - y coordinate; - handle;
block 3:
- x coordinate; - y coordinate; - handle;
I've just got the second part (retrieving info from the blocks), but when it comes to connect to the DB I'm completely lost.
For the DB I'm using XAMP for Windows, thus using localhost, user ('user123'), pass ('pass123') and table ('table123'). The table has ID (PriKey and AutoInc), px, py and hdl fields.
I don't have a clue where the '-450567.0' is coming from.
I'm in Model Space in 'World' UCS, and I'm confused.. why does the 'ID'd' value not reflect whats going on when I use the vla-get-coordinates approach.
There are many other LWPolylines within the same model that behave normally.
What I am trying to do is create a selection set of the "y" values of text. I've started by pulling out all the text on the drawing, but I need it to continue to grab only the "y" values of the text on the drawing.
I cannot determine what triggers this but the command line has stopped returning values from lisp expressions.
eg. If I type (setq fred "Hello") I would expect to see "Hello" returned. I am getting nothing. Similarly if I type !fred I get nothing. If I restart AutoCAD the problem goes away. The after some time it happens again. Is there a toggle or switch or system variable that I'm not aware of?
find duplicate Text & highlight with any color (numbers or text string) ? I have a drawing and have to find duplicate text string, file is bigger and need make this automatic find, & highlight the duplicate text.
I have a text file with a list of image tile names with their bottom left hand easting and northing see attached. I have a lisp that asks for the name of the image then should insert the image at its coordinate with a predefined scale and rotation but it isn't working so I would like an alternative method to test.
I am using 2008 and I have a dynamic block with attributes that I want to insert with the below program and have the attritute values filled in automatically. I have done this with other programs in the past and they worked great with literally no problems. They were not dynamic blocks may be the reason this does not work. Why the block will not fill in the attributes like it should. Occasionally in my testing I see a message about "units" when I am inserting the block but I have my insunits set to 0. I have attached one of the blocks I want to use. I am thinking either you cannot do this because it is a dynamic block or there is a new variable that won't let it work.
