Template drawing are the key to making AutoCAD simple. I always used Lee Mac's Steal from Drawing lisp to add Blocks, Layers, Linetypes, Dimension Styles, Text Styles, Table Styles, MLeader Styles, MLine Styles, Layouts, Page Setups, User Coordinate Systems, Named Groups, Views, Layer States, Scales, Materials, Named Viewports, Drawing Properties and Custom Properties All you need is to manage a template file with everything you need and you can add any and all you want to the current drawing with a single macro. Thanks Lee!

Here is something simple I threw together a while ago. Not everything you want, but should help. I started a more extreme version with more options back when people were posting they couldn't get TotalBoundary and SuperBoundary any longer. I'll try to get back on it this week, in the mean time, if you could post a drawing with some before and after it would help. I have no idea what all TotalBoundary and SuperBoundary does, it may help to explain exactly how you need to select and exactly what should be a boundary in your drawing it might might it easier.

Drawing the line would also pick up 4 lines across the block. would maybe have to do a fence ssget. and if block draw a bounding box to pick up lines but even then could be inaccurate if not a square.

This is sad news and a little concerning that no explanation is being given. On the face of it, it looks like a complete disregard for the community - I hope that's not true. What is true is that community engagement on forums like this has declined in recent years. Some of that decline is a result of AI. I know that this site has been scraped by LLM bots and, as a result, people seeking answers don't need to visit the site if an AI agent can provide the answer. Just to let you know, I have no intention of closing or suspending this forum any time soon.

@Nikon The "COND" statement will stop as soon as it meets the criteria for the square area range, so if something else meets the that area range before getting to your desired state, it will never get there. You will have to do a different comparison that is unique to the criteria. Maybe to change the criteria for the conditional statement to comparing the Length and width specifically, rather than with the area, or a combination of the area and the width, or something else, like a unique layer or color. Maybe something like this instead (you can alter to suit the fudge factor for the viewport height and width): (cond ((and (> 290.0 ViewPortHeight 300.0) (> 600.0 ViewPortWidth 650.0));; Compare the width and height directly! (vla-put-ConfigName Layout "DWG To PDF.pc3") (vla-put-CanonicalMediaName Layout "UserDefinedMetric (297.00 x 630.00мм)") ) ((and (> 290.0 ViewPortHeight 300.0) (> 835.0 ViewPortWidth 845.0)) (vla-put-ConfigName Layout "DWG To PDF.pc3") (vla-put-CanonicalMediaName Layout "UserDefinedMetric (297.00 x 841.0мм)") ) ... ;; Repeat for all desired sizes ) NOTE: You would also have to do both a landscape version and a Portrait version if you need both. Perhaps a bit more sophisticated comparison: (cond ((or (and (> 290.0 ViewPortHeight 300.0) (> 600.0 ViewPortWidth 650.0)) (and (> 290.0 ViewPortWidth 300.0) (> 600.0 ViewPortHeight 650.0)) ) (vla-put-ConfigName Layout "DWG To PDF.pc3") (vla-put-CanonicalMediaName Layout "UserDefinedMetric (297.00 x 630.00мм)") ) ((or (and (> 290.0 ViewPortHeight 300.0) (> 835.0 ViewPortWidth 845.0)) (and (> 290.0 ViewPortWidth 300.0) (> 835.0 ViewPortHeight 845.0)) ) (vla-put-ConfigName Layout "DWG To PDF.pc3") (vla-put-CanonicalMediaName Layout "UserDefinedMetric (297.00 x 841.0мм)") ) ... ; Repeat for all desired sizes (T (vla-put-ConfigName Layout "None")) ; Default to No plotter for non-standard sizes ) NOTE: I can't test this directly without a "real world" sample drawing to compare, along with your pc3 file, so I'm trying to give you the knowledge to do it yourself, which is preferrable anyway.

chr instead of string. (cons 1 (strcat (rtos (/ area 1000000.0) 2 2) "m" (chr 0178))) also might be the font your using. https://www.cadtutor.net/forum/topic/75383-text-ascii/#findComment-596226

@pmadhwal7 Looks like you had this same problem in 2019. MLEADERS were suggested to you then and you didn't try the tools offered? I did the following with a LEADER to MLEADER conversion very quickly:

100% setenv is writing strings to your windows registry. not good if you are doing that for all variables. might want to check to see what else you have been writing there. HKEY_CURRENT_USER\Software\Autodesk\AutoCAD\R##.#\ACAD-####:###\Profiles\<<Unnamed Profile>>\Variables tho setenv will persist even after reboot. overkill for most variables need in lisp. like @pkenewell said you should be good with just global variables. that holds while the drawing is open but make them unique. if you need to hold a variable in the drawing itself. use ldata that will persist in the drawing. so you can close and reopen it.

Or using the method proposed by @Stefan BMR we could automate in lisp like this: (enter the distances when the cursor is on the tracking line to get the desired angles) (defun des_vec (lst col / lst_sg) (setq lst_sg (list (cadr lst) (car lst))) (setq lst (cdr lst)) (while lst (if (cadr lst) (setq lst_sg (cons (cadr lst) (cons (car lst) lst_sg))) ) (setq lst (cdr lst)) ) (setq lst_sg (cons col lst_sg)) (grvecs lst_sg) ) (defun c:pl90-45 ( / old_set p1 p2 lst_pt msg) (setq old_set (mapcar 'getvar '("GRIDMODE" "ANGDIR" "ANGBASE" "POLARANG" "POLARMODE" "AUTOSNAP" "SNAPANG" "ORTHOMODE"))) (initget 33) (setq p1 (getpoint "\nPick start point: ")) (initget 33) (setq p2 (getpoint p1 "\nReference start angle: ") lst_pt (list (list (car p1) (cadr p1))) msg "\nGive distanve in the direction of cursor: " ) (mapcar 'setvar '("GRIDMODE" "ANGDIR" "ANGBASE" "POLARANG" "POLARMODE" "AUTOSNAP" "SNAPANG" "ORTHOMODE") (list 0 0 (angle p1 p2) (* 0.25 pi) 3 2 (angle p1 p2) 1) ) (initget 303) (while (and (setq p2 (getpoint p1 msg)) (/= p2 "C")) (cond ((/= p2 "U") (setq p2 (list (car p2) (cadr p2))) (mapcar 'setvar '("AUTOSNAP" "SNAPANG" "ORTHOMODE") (list 10 (angle p1 p2) 0) ) (setq p1 p2 lst_pt (cons p2 lst_pt) msg "\nGive distanve in the direction of cursor or [C/U] for Close or Undo : " ) ) (T (setq lst_pt (cdr lst_pt) p1 (car lst_pt) ) ) ) (redraw) (des_vec lst_pt 7) (initget 302 "C U") ) (entmake (append (list '(0 . "LWPOLYLINE") '(100 . "AcDbEntity") (cons 8 (getvar "CLAYER")) '(100 . "AcDbPolyline") (cons 90 (length lst_pt)) (if (= p2 "C") '(70 . 1) '(70 . 0)) ) (mapcar '(lambda (x) (cons 10 x)) lst_pt) ) ) (mapcar 'setvar '("GRIDMODE" "ANGDIR" "ANGBASE" "POLARANG" "POLARMODE" "AUTOSNAP" "SNAPANG" "ORTHOMODE") old_set) (prin1) )

fixed an error with substr to only remove the first char of the string. and added your + option.

@mhupp great code no reason why input could not be 7.7;-12;22.8;12;-5.9;21.6;-0.5;\3.5;8;2.5;\1.5;13.8 in this case each leg is separated by a semi colon, or more often a comma is used. Could type in say notepad and copy and paste to a getstring. The reason for the paste rather than type direct would be if made a mistake you UNDO fix in notepad and do again. Use "parse to list" defun. @Ataim what do you think about that idea ?

If I understand correctly your request, I think you can get the same with the right settings. Just aim the desired direction and specify the distance.

Your points will fall on the grid lines not inside the boxes created by the grid lines.

In other words, you are having trouble understanding the concept of interpolation, correct? The mathematical interpolation of contours goes like this. Let's say we have two spot elevations A & B. A = 32.7 and B = 54.0. The distance between A & B = 50 feet. We want to know where our 40-foot contour would fall between spot elevations A & B. First obtain the total elevation difference. This is done by subtracting A from B. 54.0 minus 32.7 = 21.3. Next, we want the difference in elevation between our 40-contour interval and the nearest spot elevation which in this case is A or 32.7. That works out to be 7.3. Now we need to calculate the distance (let's call this "d") we need to go from spot elevation A to our 40-foot contour. That takes the form of: d/7.3=50/21.3 or d=7.3*50/21.3 = 7.3*2.347 = 17.13 or the distance, in decimal feet, to our 40-foot contour. Got all that? Good. Now go start interpolating.

I am not good as the others but try this. It will build what you want to achieve but not exactly as what was shown in the image. Maybe other can improve the code.

Nice program as always Tharwat. I think what the OP need is create a table as attached for visual reference.

I would ask that you delete your drawings. Why? Because another student could come along and borrow them, make minor changes then submit them as their own drawings thus saving hours of labor. You do all the work and they get the credit. Not kosher at all. Follow me? Addendum: Looks like someone has already done exactly that. Again, take your drawings down. There are plenty of image files (not CAD files for students) to reference. Thank you.

The OP seems to have exited the conversation, but just for others with the same inquiry. As I have mentioned, this is mostly an issue with your PDF editor, the instructions for using the OCR should be in Foxit Help. If this is something you need to do going forward without any effort, you need to use TTF.

As most of us use Microsoft Office products I switched from using AutoCAD's Swiss Lt BT TrueType font to ArialNarrow.ttf like SLW210 suggested as it's horizontally compressed to take up less space while being even more easily readable. While hindsight doesn't fix your immediate problem finding a font that doesn't cause issues with your PDF software before you need to output one to PDF again would solve your issues in the future. I've struggled with the same issue even with the full paid version of Adobe with drawings by others usually because of SHX text with various width factors. Never do that with a DWG you want to output to PDF unless you don't want anyone to convert that text back again.

I opened your PDF in Acrobat Pro and the text was editable. This seems to be a Foxit issue, though as mentioned, you might want to use a TTF font if that's what Foxit needs. ArialNarrow.ttf is a common replacement IIRC to ISOCP.shx

Works with BricsCAD. I know you have to wrap points in AutoCAD sometimes with (vlax-3d-point pt2) not sure about entmake tho.

Thanks!! it's working fine. It's okay if it's not exactly the same from mine but as long as it can generate the table it's fine. saved me a lot of time.

Thank you I can use this as well...

yah it is... I overlooked it. All good now.

Gotcha, thx Remark

not sure what your trying to do. you can set entlast before the explode then add all the entities into the selection set. (setq LastEnt (entlast)) (command "_.explode" ss) (setq SS1 (ssadd)) ;create a blank selection set or add to an existing one. (while (setq LastEnt (entnext LastEnt)) (ssadd LastEnt SS1) )

I tried this as a test, so finds the #1234 text. It will find 123#456 also. But the lisp as suggested by @Steven P should cater for that. (setq ss (ssget "X" (list (cons 0 "*text")(cons 1 "*#*")))) (princ (sslength ss)) 12

Why not just use the built-in FIND command in AutoCAD? You just have to turn off the "Use Wildcards" option.

Have a go at adding this vehicle, they are daunting when you meet them on the road. Let alone the 3 x 19m petrol tankers. Recording 2026-03-01 183700.mp4

Such a tool would be https://www.theswamp.org/index.php?topic=58808.0

Unfortunately not with the current version, but I'll certainly consider implementing this functionality in a future version.

In PDF-XChange Editor, I could only edit the Title Border Text. All the node text isn't editable. Using OCR in PDF-XChange, it converted all 5 pages in about 15 seconds. I am using the paid-for version, so not sure if OCR is available in the free version.

Just do a google you should be able to find a ISO.TTF font there are thousands of fonts out there. You open c:\Windows\fonts and drag the TTF onto it from memory. ISO3098B ? If your lucky some one may have one already.

I can do that most of the time with the OCR (Optical character recognition) in Adobe Acrobat Pro. I thought Foxit has an OCR.

You may not have a choice here, but can you convert your text to TTF from SHX? PDF should accept that as text.

You have a Table in your images, you can change all or one cell in a table with respect to the font style. Is that what your asking for ? If so post an example table dwg. Something like this (vla-SetTextStyle Objtable (+ acDataRow) "Arial") in a lisp.

There are several LISP programs around for stripping MTEXT. Solved: strip mtext formatting - Autodesk Community Re: StripMText Issue - Autodesk Community In the MText Editor there is a down arrow on the top right, scroll down to Remove Formatting.

Not sure if this will work the way you want. I created a dummy drawing with a dummy block and a dummy attribute. When you set the attribute to Invisible, you can't see it any more, but you can edit it. I know, that's not what you want. I include it so you don't waste time trying it for yourself. When you set the attribute to Constant, you can't edit it at all. It no longer shows up in the Properties, and it doesn't show up in the block. If you change the attribute back to not constant, you can insert a new block and give it a different value, but it's still invisible and it does show up in Properties. Could be a bug? Or the way I handled it.
