I did not know that was a feature, sorry about that!!

This one is great! I'd love to see the updated one when its ready. I didn't realize I had tried it with the other version, but this one works great. Thanks again

oh posted at the same time as pkenewell :-)

first of all , if is a built in command so c:if I don't think works second , yes and no are variables not functions so you could use (setq yes "\nYes") and then use (eval yes) better would be : (defun c:whatif (/ inp yes no) (setq yes "Yes" no "No") (if (= (setq inp (getint "\nValue: ")) 1)(eval yes)(eval no)) ;;; or (if (= (setq inp (getint "\nValue: ")) 1)(princ "\nyes")(princ "\nNo")) (princ) )

If you want to use an IF statement with a variable that could be something or NIL, simply use this construct: (defun C:IF () (setq i (getint "\nEnter a Number or ENTER for nothing: ")) (if i ;<-- If not nil (progn (princ (strcat "\nYou entered the number " (itoa i) ". ")) T ) (progn (Princ "\n You did not enter anything. ") nil ) ) ) Conversely if you want to check for a NIL condition: (defun C:IF () (setq i (getint "\nEnter a Number or ENTER for nothing: ")) (if (not i) ;<-- If nil (progn (Princ "\n You did not enter anything. ") nil ) (progn (princ (strcat "\nYou entered the number " (itoa i) ". ")) T ) ) )

Yes, that had some issues, I think I have that sorted, but not ready to repost. Still working on adding the DCL to it. It happens to me all of the time. No worries!

I have recently updated a batch of blocks changing all labels from text to attributes, the idea being to stop them mirroring. After competing this task I find that the attribute text still mirrors. I think it is because the attributed blocks are nested. Is there any way to stop this? The attached block shows the issue. jam2.dwg

Hi This is a pretty complex block attached. All the parts are spaced out at mo while I am getting things working, once done they are all moved in line. We make beams 2,3,4,5&6m lengths. To make up 7m we use 4+3, to make up 8 we use 5+3, 9-5+4, 10-6+4, ....13-6+4+3 etc etc. i have defined the available viz states Issue is we terminate the beam ends in 1 of 3 ways also we run beams lengths upto 50m at times. Only 1 viz state allowed in autocad (although i did see a link containing a block with multiple viz states but i think that involves some pretty high end programming skills), so I have been playing with using dummy parameters. It works well (attached). My issue is that I need to create many many hundreds of lines of data to encompass the full range I am looking for . jam1.dwg

After being stuck on this subject for a while, I know the answer is "don't use variables for the actions of an if statement" but I am still bothered as to WHY it does not work. I assume it has to do with the way the if function evaluates, but I cannot figure it out myself. I apologize in advance for the long read. For example, I created a short routine to give a positive or negative response dependent on whether or not the user input equals 1: (defun c:if (/ inp) (setq inp (getint "\nValue: ")) (if (= 1 inp) (print "You Did It!!!!!!!!!") (print "You FAILED") ) (princ) ) This routine works- I provide the action for the T or nil outcome within the if statement. However, if I assign variables instead: (defun c:if (/ inp yes no) (setq inp (getint "\nValue: ") yes (print "You Did It!!!!!") no (print "You FAILED") ) (if (= 1 inp) yes no) (princ) ) The routine doesn't know what to do with itself regardless of user input. It returns the nil outcome twice regardless of whether or not the user input value equals 1. I do not understand why it skips to the nil outcome if the statement is true.

After seeing your post I realized I was trying it with the wrong LISP. I was trying it with TMTMS and that was giving me the results that had the space and wasn't numbering anything. Just tried it with this one 'FNRSEQ' and it works perfectly. Thank you so much for this.

Thanks for this, learned something new, much cleaner and easier. I tried your suggestion, but didn't work, I also did some more testing and the reading of the data is done properly, the appending of the new content is done properly, and then I think the problem occurs when creating safearray using value 17 or in other words using VisualLisp variant data type vlax-vbByte, which is unsupported according to this post. So the value that has been returned from vlax-variant-type performed on result of reading with (LM:ReadBinaryStream (findfile "../AppAutoLoad.app") nil) is 8209 which is value of vlax-vbArray(8192) combined with vlax-vbByte(17), but since the vlax-vbByte data type seems to be unsupported I guess that I can't recreate the variant of the same type (8209) anymore?

Thank you very much! I'm not sure if I understand you, you mean reading excel directly using AutoLISP? I never tried to do anything with excel and LISP together. When I have data in excel I use VBA and calling LISP scripts from VBA. The sample data set attached - there are 4 columns, file, bhd_ins - block handle that needs to get the "data injection", bhd_type and bhd_line - are the names of attributes in that block. The block handles in the sample set correspond to the real handles on the sample drawing. The content of bhd_type and bhd_line is made up, but that won't make a difference. sample_drawing.dwg handle_table.xlsx

FWIW, you can change this: (mapcar 'ascii (MM:strToLst text)) To: (vl-string->list text) An untested suggestion: where the variant is concerned, rather than using hardcoded variant & safearray datatypes, try querying the types of the original variant & safearray using: vlax-variant-type vlax-safearray-type

Thanks for advice, I tried that already but no success, it seams like is not possible to write to binary files using standard write-line command. That's why I went from this solution from Lee Mac which is using ADO Stream object and it works fine when reading with LM:ReadBinaryStream and then writing the result of that function (whic is vlax-variant) back to the file using LM:WriteBinaryStream, but when I try creating my own vlax-variant object and write it back to the file it doesn't go as expected. Yes. it does, I'm using them in my code, but problem occurs while building vlax-variant object which is needed for writing data back to the file, somehow only zeroes are written and I can't figure out why.

Another go. (defun c:addval ( / lst lst2 att cnt lst3) (setq inc (getreal "\nEnter increment + or - ")) (setq ss (ssget '((0 . "TEXT,ATTDEF")))) (setq lst '() tnum 0 tatt 0) (repeat (setq x (sslength ss)) (setq obj (vlax-ename->vla-object (ssname ss (setq x (1- x))))) (setq objname (vlax-get obj 'objectname)) (if (= objname "AcDbText") (progn (setq newt (+ (atof (vlax-get obj 'textstring)) inc)) (cond ((< newt 10 ) (setq newt (strcat "00" (rtos newt 2 0)))) ((< newt 100) (setq newt (strcat "0" (rtos newt 2 0)))) (setq newt (rtos newt 2 0)) ) (vlax-put obj 'textstring newt) (setq tnum (1+ tnum)) ) (progn (setq newt (+ (atof (vlax-get obj 'tagstring)) inc)) (cond ((< newt 10) (setq newt (strcat "00" (rtos newt 2 0)))) ((< newt 100) (setq newt (strcat "0" (rtos newt 2 0)))) (setq newt (rtos newt 2 0)) ) (vlax-put obj 'tagstring newt) (setq tatt (1+ tatt)) ) ) ) (alert (strcat (rtos tnum 2 0) " text changed \n" (rtos tatt 2 0) " tags Changed")) (princ) )

@CivilTechSource Yes you can make the variable global by not clearing it in the lisp routine. If you aren't familiar with what I am taking about in a lisp you write at the top this.. (defun c:lisp ( / variable1 variable2) ) If you set a value to variable3 as long as it's not in the list like variable1 is then it's consider a global variable which can be used by multiple lisps. Typically I see people use something like global:variable1 to know which is which. Hope that helps.

You mention reading from Excel, its not a problem you can read cells from CAD, so if you have multiple blocks can be done. It would be simple to add to your defun say two columns in Excel Blocknames & dwgname with path. Need a sample Excel.

A suggestion use a "\n" in the (getreal "\nEnter Rise...) this will push a new line on the command line. If the F2b is a global variable then any lisp can read it, but that is not necessarily a good idea. Its easier to do a double lisp in the cui. So load the program and call a defun passing it the f2b value. ^C^C^P(setq F2B (getreal "Enter Rise for Front to Back slopes: "))(load "mylisp")(mylisp f2b) I use LDATA when I want values stored in a dwg they stay in the dwg and can be changed.

You can have lisp in a CUI I have set a variable then load a lisp using that variable. Simple answer ^c^C^p(setvar 'textsize (getreal "\nEnter text height "))(load "mylisp") There is a textbox input trying to remember it someone else will post. It is a built in function. Or can do something like this, another DCL example is at Afralisp. ^c^c^p(if (not AH:getvalsm)(load "Multi Getvals.lsp"))(setq ans (AH:getvalsm (list "Enter text height " "height" 5 4 "2.5")))(load "mylisp") Multi GETVALS.lsp

I think we are struggling to see what you want, if you type 1-2-3 as entry its easy to split it apart based on the "-" into 3 variables . Maybe make a movie if you don't want to post the block.

Works fine on your drawing here. Post that drawing if possible, looks like something in the Mleader MText. Post the command line as well. Command: FNRSEQ Enter FIND text: 03 Enter starting REPLACE number (e.g. 01): 01 Enter line number for MTEXT/Multileader (or type 'All'): 1 Select objects: 1 found Select objects: 1 found, 2 total Select objects: Specify opposite corner: 0 found Select objects: 1 found, 3 total Select objects: 1 found, 4 total Select objects: Sequential find & replace completed.

Rather then reading the file and then writing it back with new data added just open the file in append mode. aka add the data you want at the end. ;; Example usage: ;; (MH:AppendText "C:/path/to/your/file.txt" "This is a new line of text") (defun MH:AppendText (filename text / file) (vl-load-com) (setq file (open filename "A")) 'open file in append (if file (progn (write-line text file) (close file) (princ (strcat "\nText appended to " filename)) ) (princ (strcat "\nError: Could not open " filename)) ) (princ) ) also ZWCAD might now be able to use some of the Visualisp commands like vlax- and vl-

You can add something like this to make the numbering 3 digits? like this (setq i 1 ) (foreach sub lst (setq lent (entget (last sub)) txt (strcat (if (< i 10) "00" (if (< i 100) "0" "")) (itoa i)) i (1+ i) ) (entmod (subst (cons 1 txt)(assoc 1 lent) lent)) )

This tool is great but I need the numbering to be in this format 001, 050....I mean that a zero accompanies the number la numeracion que aqui manejamos usa 3 digitos
