For example, if I move a marker like 'EL. 1'-0"' up by 2', it correctly updates to 'EL. 3'-0".' However, it doesn't handle negative values as expected. If I move 'EL. -1'-0"' by 2', it changes to EL. -3'-0"' instead of the correct EL. 1'-0". Another example is if I move EL. -5'-0" up by 2', it should update to 'EL. -3'-0",' but instead, it incorrectly changes to EL. -7'-0". Thanks in advance for your help.

Also, if you have suggestions for alternatives other than just combining all the commands, I’d love to hear those too. Thanks in advance to all.

Hello everyone. This is my first time posting but i have enjoyed a lot of your great work. I use a lot a field about object/polyline/length - decimal 0 (copy it to different polylines and than get their lenghth) and i am tired of changing object from dialogbox. Is there an easy way (lisp or other) to change the object directly and get its length:):)

Hi all, I need some help from pros, but my English is not good . I'm use this 1 command to align the text with custom insertion point and evenly distributed, the issues are listed below, 1. When I select the text entities with green window (snap-1) it reorder all text entities by itself (snap-2), I might select a group of texts labeled 5 to 7 first, then select another group from 1 to 4, and finally include text labeled 8. However, when I look at the selection afterward, the order is not what I expected (snap-2); it seems to rearrange itself instead of keeping the sequence I selected them in.

Hi all, Again I have found a lisp Lee Mac made that copies a field into a dimension, "copyfield", but it requires that the field already exists... So is there a way to create a field from an attribute in a block and then insert the field directly into a dimension? Thanks in advance.

Hello good afternoon, First of all, I apologize but I don't have any kind of training in programming and I try to get by with the tools I have at my disposal (forums, YouTube, AI,...) I am a topographic engineer and I needed a lisp that would draw the grid the way I wanted, I have already developed much of it using the methods mentioned above but now I am stuck in creating the coordinate text. According to my analysis, it must be the justification of the text, I say this because even doing an isolated test on the creation of the text (entmake) the justification remains by default. The following image is a representation of the final result. I'll leave my humble lines of code attached so that a kind soul can help me Thank you for taking the time to read the post Grid__.lsp

I have difficult time finding a command that would match a block's attribute (text height, text rotation, and text scale) with a source block. I had found a LISP routine that would match the block itself with a source block but it did not include attributes. I don't need to match attibute values, just the properties. I'm using AutoCAD 2012 with regular blocks (not dynamic)

Suppose that there are discrete texts in different places of the layout, for example, apple, orange, banana, lemon.

I have drawing with a bunch of blocks with attributes tags. Among the attribute tags the following three are of importance: ID Next Previous The ID attribute values are already entered in the blocks and are unique. I would like to have a lisp that will enable me to sequentially pick the blocks and fill in the Next and Previous attributes tags with the ID values. Attached is sample file showing the starting point and expected end result. Any ideas how to go about making this lisp? EDIT: I have been able to modify a lisp from @Lee Mac as fist step. But it only works in forward direction i.e to fill in Previous attribute. Im thinking that to get the functionality to fill in "Next", we cannot use single item selection, we will have to use list selection to get the iD of next block and fill in the current block in "Next" Attribute. So the operation sequence will be Start lisp> Click all blocks one by one> hit Enter Any help in achieving this will be welcome.

I am looking for a routine to sort contour lines. I am using 3d polylines that I import from Global Mapper. My problem is all of the lines are on one layer. Ideally, I would like to pick a starting elevation (polyline) and have the routine select every 5th contour up and down. Once then are all selected, I can move them to a new layer (like TOPO-INDEX). Some of these sites are hundreds of acres and have significant elevation changes. To do this by hand is VERY time-consuming (and easy to miss some contours). I am not a programmer, but this seems like the type of task that is ideal for a lisp routine. Any help is appreciated.

Hi guys, I've been trying to figure out a way to insert a new block in a project that already has one with the same name. I would like to have something asking me if I want to keep the old one or replace/overwrite with the new one. Keeping the placement of the old block in the project. I know that AutoCAD keeps the old version on a block if it has the same name as the new one, having to remove all instance of the block and purge all. Why wouldn't AutoCAD asked me ; [There is a block with the same name in your project, Would you like to; Overwrite, Rename, Cancel] Just like in file explorer on desktop. Anyway, maybe I'm asking to much let me know guys if you have a suggestion, either a LISP or a command that I'm not aware of yet in AutoCAD.. Thanks

I've tried this lisp command that ChatGPT gave me but with little to no success; (defun c:BreakAndShorten ( / pt line break_length startpt1 endpt1 startpt2 endpt2) (setq break_length 2.5) ; Set your desired shorten length here (2.5 mm in this case) (setq line (car (entsel "\nSelect the line to break: "))) (setq pt (getpoint "\nSelect the break point: ")) (if (and line pt) (progn (setq startpt1 (polar pt (angle pt (vlax-curve-getStartPoint line)) (- break_length))) (setq endpt1 pt) (setq startpt2 pt) (setq endpt2 (polar pt (angle pt (vlax-curve-getEndPoint line)) break_length)) (command "BREAK" line startpt1 endpt2) (setq line1 (car (entsel "\nSelect the first segment to shorten: "))) (setq line2 (car (entsel "\nSelect the second segment to shorten: "))) (if line1 (command "LENGTHEN" "DE" (- break_length) line1)) (if line2 (command "LENGTHEN" "DE" (- break_length) line2)) ) (alert "You must select a line and a break point.") ) (princ) ) In sum, I want to break one line at a point and then shorten the 2 segments by 2.5mm so it has a 5mm gap without using multiple command everytime

Hello, I am searching for a lisp that can export the lengths of all selected polylines and export them to either Excel or an AutoCad table. I have found and tested around 20 lisps but so far cannot find the right one. There were only 2 that look promising, maybe they could be modified? One was by Lee Mac and the other Jimmy Bergmark. I can post the 2 Lisp if needed. The lisp would need to have you select multiple polylines and give the total lengths of each polyline in the order that they were selected in. Then the data would either appear on an AutoCad table or Excel. Thanks for any help that can be provided.

Hi, i have multiple polylines in a series and block are placed on them. i want to select the polylines between two selected blocks. sample file is attached. Thanks, Srikanth select_between _two_blocks_sample.dwg

Hi guys I'm not sure that this is possible but hey you guys know a hell of a lot and surprise me often. Is it possible in lisp to look inside a text file and remove some text from between 2 keywords? For example The text filename would be the same as the cad file, but it's on another network location. I can create a variable that concatenates the file name and location. This I know I can do lol. Then I want the lisp to open the file find Keyword1 and keyword2 (always the same and only ever 1 of each in the file, also there would always be text before and after the keywords which should be kept intact). Then remove any text that lies between them. And finally resave the file. I've done some searches but I keep getting results for editing text inside of cad, which isn't what I'm after, or recommending using other programming language, but I've no idea how to do that. Which is why I'm pinning my hopes on this.

Hello everyone, I'm wondering if it is possible to create a lisp that could attach several images to AutoCAD 2010 at the same time and create a new layer that has the same name like an image for each image. I downloaded georefimg app that put an image in certain place in AutoCAD based on world file but it is necessary to do this for each image separately. In case of this app first thing to do is attach one image to CAD and afterwards I can use georefimg to choose an image (that was inserted before) in order to put this in proper section. But it could be faster and more efficient if I would attach many images equally in random place and after that use this georefimg for all images. If someone has some idea how to prepare sth like this I'll be grateful for any suggestions in this case. Best wishes, Jakub

Can anyone help me to write a code ?? Which Identifies each closed polyline (rectangle) on the "ss-bor" layer. Finds the text entity (content) of text on the "ss-pre" layer which is within (rectangle) on the "ss-bor" layer . Selects all entities on the "ss-part" layer within the (rectangle) on the "ss-bor" layer. Creates a block using the text value from the "ss-pre" layer as the block name, including all selected entities from the "ss-part" layer within the (rectangle) on the "ss-bor" layer. and loop though each (rectangle) on the "ss-bor" layer and make block of each as above mentioned.. For information i have attached my dwg file G27.dwg

Can someone help me out with changing the attributes of a block using a list. The block is used in a leader. The block has 7 attributes, but my list doesn't always contain 7 variables. I have tried to implement Lee Mac's code dynamicblockfunctions, but I keep getting the error "too few arguments". I would like to import the leader when the calculation is done, and for the block to then automatically change the attributes to the variables in the list. Here's my current code: (defun c:testKRIS ( / *error* dch dcl des mv d1 d2 d3 d4 d5 d6) (defun *error* ( msg ) (if (and (= 'int (type dch)) (< 0 dch)) (unload_dialog dch) ) (if (= 'file (type des)) (close des) ) (if (and (= 'str (type dcl)) (findfile dcl)) (vl-file-delete dcl) ) (if (and msg (not (wcmatch (strcase msg t) "*break,*cancel*,*exit*"))) (princ (strcat "\nError: " msg)) ) (princ) ) (cond ( (not (setq dcl (vl-filename-mktemp nil nil ".dcl") des (open dcl "w") ) ) (princ "\nUnable to open DCL for writing.") ) ( (progn (foreach str '( "ed : edit_box" "{" " alignment = left;" " width = 20;" " edit_width = 10;" " fixed_width = true;" "}" "" "test : dialog" "{" " spacer;" " key = \"dcl\";" " : ed" " {" " key = \"mv\";" " label = \"MV:\";" " }" " :boxed_column { " " label = \"Diepte vd buizen\";" " :row {" " : ed" " {" " key = \"d1\";" " label = \"A:\";" " }" " : ed" " {" " key = \"d4\";" " label = \"X:\";" " }}" " :row {" " : ed" " {" " key = \"d2\";" " label = \"B:\";" " }" " : ed" " {" " key = \"d5\";" " label = \"Y:\";" " }}" " :row {" " : ed" " {" " key = \"d3\";" " label = \"C:\";" " }" " : ed" " {" " key = \"d6\";" " label = \"Z:\";" " }}" " }" " : boxed_row" " { " " label = \"BOK berekeningen\";" " :column {" " : ed { key = \"res\"; label = \"BOK:\"; is_enabled = false; }" " : ed { key = \"res2\"; label = \"BOK2:\"; is_enabled = false; }" " : ed { key = \"res3\"; label = \"BOK3:\"; is_enabled = false; }" " }" " :column{" " : ed { key = \"res4\"; label = \"BOK4:\"; is_enabled = false; }" " : ed { key = \"res5\"; label = \"BOK5:\"; is_enabled = false; }" " : ed { key = \"res6\"; label = \"BOK6:\"; is_enabled = false; }" " }" " }" " : button" " {" " key = \"cal\";" " label = \"Calculate\";" " }" " spacer;" " ok_only;" "}" ) (write-line str des) ) (setq des (close des) dch (load_dialog dcl) ) (<= dch 0) ) (princ "\nUnable to load DCL file.") ) ( (not (new_dialog "test" dch)) (princ "\nUnable to display 'test' dialog.") ) ( t (set_tile "dcl" "Calculate Area") (action_tile "mv" "(setq mv $value)") (action_tile "d1" "(setq d1 $value)") (action_tile "d2" "(setq d2 $value)") (action_tile "d3" "(setq d3 $value)") (action_tile "d4" "(setq d4 $value)") (action_tile "d5" "(setq d5 $value)") (action_tile "d6" "(setq d6 $value)") (action_tile "cal" (vl-prin1-to-string '( (lambda ( / m x y z a b c lijst_results ) (setq lijst_results '()) (set_tile "res" "") (set_tile "res2" "") (set_tile "res3" "") (set_tile "res4" "") (set_tile "res5" "") (set_tile "res6" "") (setq m (distof mv)) (if m (progn (setq lijst_results (append lijst_results (list (strcat "mv: " (rtos m 2 2))))) (if (and d1 (setq a (distof d1))) (progn (setq lijst_results (append lijst_results (list (strcat "A: " (rtos (- m a) 2 2))))) (set_tile "res" (rtos (- m a) 2 2)))) (if (and d2 (setq b (distof d2))) (progn (setq lijst_results (append lijst_results (list (strcat "B: " (rtos (- m b) 2 2))))) (set_tile "res2" (rtos (- m b) 2 2)))) (if (and d3 (setq c (distof d3))) (progn (setq lijst_results (append lijst_results (list (strcat "C: " (rtos (- m c) 2 2))))) (set_tile "res3" (rtos (- m c) 2 2)))) (if (and d4 (setq x (distof d4))) (progn (setq lijst_results (append lijst_results (list (strcat "X: " (rtos (- m x) 2 2))))) (set_tile "res4" (rtos (- m x) 2 2)))) (if (and d5 (setq y (distof d5))) (progn (setq lijst_results (append lijst_results (list (strcat "Y: " (rtos (- m y) 2 2))))) (set_tile "res5" (rtos (- m y) 2 2)))) (if (and d6 (setq z (distof d6))) (progn (setq lijst_results (append lijst_results (list (strcat "Z: " (rtos (- m z) 2 2))))) (set_tile "res6" (rtos (- m z) 2 2)))) (print lijst_results) ) (alert "Vul maaiveld waarden in.") ) ) ) ) ) (start_dialog) ) ) (*error* nil) (princ) )

I want to change the values of a dynamic block within a lisp. This lisp contains a calculation. I used .dcl for this. My dynamic block has 7 attributes: maaiveld, HOOGTE1, HOOGTE2, HOOGTE3, HOOGTE4, HOOGTE5 and HOOGTE6. My lisp code has 7 values: m, a, b, c, x, y and z The order of these outputs are important. a, b, and c are sewer pipes that arrive in the cewer, and x, y, and z are pipes that depart from the sewer pit. So if there are only 2 pipes, we only have to use a and x. This makes it difficult. I can't just set HOOGTE1 to a, HOOGTE2 to b, HOOGTE3 to c, etc. If I do it this way, it will leave a gap in my leader. I hope this is even possible. I provided some screenshots of my calculator and of the leader, and the problem of the gap. Maybe I just need to create a more complex dynamic block, so that I can just connect the hoogte1,2,3,... to a,b,c,... I really don't know. code: (defun c:testKRIS ( / *error* dch dcl des mv d1 d2 d3 d4 d5 d6) (defun *error* ( msg ) (if (and (= 'int (type dch)) (< 0 dch)) (unload_dialog dch) ) (if (= 'file (type des)) (close des) ) (if (and (= 'str (type dcl)) (findfile dcl)) (vl-file-delete dcl) ) (if (and msg (not (wcmatch (strcase msg t) "*break,*cancel*,*exit*"))) (princ (strcat "\nError: " msg)) ) (princ) ) (cond ( (not (setq dcl (vl-filename-mktemp nil nil ".dcl") des (open dcl "w") ) ) (princ "\nUnable to open DCL for writing.") ) ( (progn (foreach str '( "ed : edit_box" "{" " alignment = left;" " width = 20;" " edit_width = 10;" " fixed_width = true;" "}" "" "test : dialog" "{" " spacer;" " key = \"dcl\";" " : ed" " {" " key = \"mv\";" " label = \"MV:\";" " }" " :boxed_column { " " label = \"Diepte vd buizen\";" " :row {" " : ed" " {" " key = \"d1\";" " label = \"A:\";" " }" " : ed" " {" " key = \"d4\";" " label = \"X:\";" " }}" " :row {" " : ed" " {" " key = \"d2\";" " label = \"B:\";" " }" " : ed" " {" " key = \"d5\";" " label = \"Y:\";" " }}" " :row {" " : ed" " {" " key = \"d3\";" " label = \"C:\";" " }" " : ed" " {" " key = \"d6\";" " label = \"Z:\";" " }}" " }" " : boxed_row" " { " " label = \"BOK berekeningen\";" " :column {" " : ed { key = \"res\"; label = \"BOK:\"; is_enabled = false; }" " : ed { key = \"res2\"; label = \"BOK2:\"; is_enabled = false; }" " : ed { key = \"res3\"; label = \"BOK3:\"; is_enabled = false; }" " }" " :column{" " : ed { key = \"res4\"; label = \"BOK4:\"; is_enabled = false; }" " : ed { key = \"res5\"; label = \"BOK5:\"; is_enabled = false; }" " : ed { key = \"res6\"; label = \"BOK6:\"; is_enabled = false; }" " }" " }" " : button" " {" " key = \"cal\";" " label = \"Calculate\";" " }" " spacer;" " ok_only;" "}" ) (write-line str des) ) (setq des (close des) dch (load_dialog dcl) ) (<= dch 0) ) (princ "\nUnable to load DCL file.") ) ( (not (new_dialog "test" dch)) (princ "\nUnable to display 'test' dialog.") ) ( t (set_tile "dcl" "Calculate Area") (action_tile "mv" "(setq mv $value)") (action_tile "d1" "(setq d1 $value)") (action_tile "d2" "(setq d2 $value)") (action_tile "d3" "(setq d3 $value)") (action_tile "d4" "(setq d4 $value)") (action_tile "d5" "(setq d5 $value)") (action_tile "d6" "(setq d6 $value)") (action_tile "cal" (vl-prin1-to-string '( (lambda ( / m x y z a b c ) (set_tile "res" "") (set_tile "res2" "") (set_tile "res3" "") (set_tile "res4" "") (set_tile "res5" "") (set_tile "res6" "") (cond ( (or (not mv) (= "" mv)) (alert "Please enter a maaiveld value.")
