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

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

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

Have you tried to turn off Object Snaps before you run the script? It looks to me as if your line is snapping to adjacent end of line points instead of plotting the listed coordinates.

I moved your thread to the The CUI, Hatches, Linetypes, Scripts & Macros Forum. Your script is missing the blank line at the bottom, so it needed that for enter at the end. Other than that, I ran it in AutoCAD 2000i on my home computer and they all look like your bottom image.

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.

Like a lot here just remember teaching your children how to drive, no did not crash into things, but went around a roundabout, hands everywhere trying to turn, change gears and me praying as we chugged out.

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.

Ok its simple to use vpoint to set your view angles, code is part of a view choice lisp. (if (= look "R")(command-s "-vpoint" "1,0,0")) (if (= look "L")(command-s "-vpoint" "-1,0,0")) (if (= look "F")(command-s "-vpoint" "0,-1,0")) (if (= look "B")(command-s "-vpoint" "0,1,0")) (if (= look "P")(command-s "-vpoint" "0,0,1")) (if (= look "3")(command "_.vpoint" "-1,-1,1")) If you want auto 3 viewports then you need to ask what scale and pick say a point in model so the views can be based around that point. I would use a layout with a title block.
