thank you for your suggestion

Long time I'm nothing written in Lisp. So, I hoppe it will serve you. Also, you can saw a short video how it works. The code: (prompt "\nTo run a LISP type: yval") (princ) (defun c:yval ( / old_osmode pline spt ept spt_pline ept_pline datum_line yval_datum_line yval_start_pline yval_end_pline txt_position ang_spt_pline ang_ept_pline datum_value intersecting_lines len i int_pt_pline int_pt_datum_line dist yval_position ang) (setq old_osmode (getvar 'osmode)) (setq pline (car (entsel "\nSelect Polyline to get an Elevation:"))) (while (or (equal pline nil) (not (equal "LWPOLYLINE" (cdr (assoc 0 (entget pline)))))) (prompt "\nSelected entity must be LWPOLYLINE.

Dear Members, I have a ployline with dautm text value and datum line , I want text label of pline start vertex, intersection pont and end vertex, based on datum. If any have plz share need only y value, elevation, level of pline . Thanks See attached cad file Thanks POLYLINE Y VALUE.dwg

I made mistake, this works only for text. As for mtext, should be: entmakex with plain content and then vla-put-Textstring with the field expression.

Give this a try, allows up to 4 values. Probably needs a bit of fine tuning. Only use it with a single line dim. Can add more lines and can change width of boxes look at 20 19. ; Add more lines to a normal Dimension ; By AlanH Oct 2025 (defun c:incdim ( / obj prec ans howmany x newstr ) (setq obj (vlax-ename->vla-object (car (entsel "\nPick Dimension object ")))) (setq prec (vlax-get obj 'PrimaryUnitsPrecision)) (setq tp (vlax-get obj 'TextPosition)) (if (= (setq len (vlax-get obj 'textoverride)) "") (setq newstr (rtos (vlax-get obj 'measurement) 2 prec)) ) (if (not AH:getvalsm)(load "Multi Getvals.lsp")) (setq ans (AH:getvalsm (list "Enter values " "line 1 " 20 19 newstr "line 2 " 20 19 "" "Line 3" 20 19 "" "Line 4" 20 19 ""))) (setq howmany "Yes") (setq x 0) (while (= howmany "Yes") (setq str (nth (setq x (1+ x)) ans)) (setq newstr (strcat newstr "\n" str )) (if (or (= x 3)(= str ""))(setq howmany "No")) ) (vlax-put obj 'textoverride newstr) (vlax-put obj 'TextPosition tp) (princ) ) (c:incdim)

Another By @Lee Mac Area.lsp look on his web site. https://www.lee-mac.com/arealabel.html

Have you defined the variables 'myfilepath' and 'myfilename' somewhere? If not, these symbols will evaluate to nil, yielding the error you have described.

The answers you seek can be found in the thread entitled... "Penn Foster Student Suffering with Oleson Village Map." I know this because I contributed instructions as well as images. Many P-F students have found the thread beneficial.

Hi It's not certain that all the functions in this code will work in AutoCAD LT. Try it. (defun c:guardA (/ v nvoD f?) (setq v (member (vla-get-saveAsType (vla-get-openSave (vla-get-preferences (vlax-get-acad-object)))) (list acr14_dwg "v14" ac2000_dwg "v2000" ac2004_dwg "v2004" ac2007_dwg "v2007" ac2010_dwg "v2010" ac2013_dwg "v2013" ac2018_dwg "v2018"))) (setq f? (if (not (vl-directory-files (setq nvoD (strcat (getvar "DWGPREFIX") "EXPORTED\\")))) (VL-MKDIR nvoD) T)) (vla-saveas (vla-get-activedocument (vlax-get-acad-object)) (strcat (if f? nvoD (getvar "DWGPREFIX")) (VL-FILENAME-BASE (getvar "DWGNAME")) "-EXPORTED_" (cadr v) ".dwg") (car v)) (princ "\nDone!") (princ) )

Thanks, I found this lisp that works for me. If anyone is interested here is the link. Visibility Selection

LT is not brilliant with VLA- or VL- commands so best really avoid them for now. Perhaps not the most efficient method but try the (command "_.saveas" ...... ) method

... have you tested that...

Here are two good options from Lee Mac

Hi all, I've been trying to accomplish what I thought would be an easy thing, but despite hours of searching I can't seem to get it to work! I'm trying to create a lisp that I can run in AutoCAD LT (2025) that does a "SAVE AS" and simply adds " - EXPORTED" as a suffix onto the original filename. I'd like this to happen without any dialogue boxes popping up, and If it could have the following features it would be absolutley perfect (but these arent crucial). 1. specify the file version from within the lisp 2. save the exported versions into a folder within the same directory called "exported" (and overwrite previous versions if they exist) The closest I've gotten is using the below code to do the saveas, but it throws an error (; error: bad argument type: stringp nil) (defun c:TEST () (vl-load-com) (vla-SaveAs (vla-get-ActiveDocument (vlax-get-acad-object)) (strcat myfilepath myfilename ".dwg") ac2018_dwg) ) If anyone is able to help me out I'd very much appreciate it

Another simple way is to entmake the mtext with a plain content first, then apply entmod DXF1 with field expression for the mtext.

You're welcome!

Are you using AutoCAD 2010 as shown in your profile? I do not believe this is an issue in newer AutoCAD versions, I am not sure what version it was fixed though. UPDATE: From the posted thread, looks like AutoCAD 17.1 update or maybe AutoCAD 2018 had the fix. AutoCAD 2023 Help | SELECTIONOFFSCREEN (System Variable) | Autodesk You'll probably need to keep searching and see what workarounds people came up with before the fix.

That LISP the is not original AFAIK. It is a couple of functions, you need to call for it with a LISP to make the settings, etc. Several places to get the correct QlSet.lsp and example LISPs to use it.

Have a look at lee-mac dynamic block properties there is a get current visibility name in there, also get all visibility names into a list.

Look at (getvar 'extmax) & (getvar 'extmin) these are the size of your dwg wether your zoomed or not.

Something I have done for attributes in a block is pop up a dcl with the current attribute values so there is no reason why could not do the same just set a maximum number of lines 1 2 3 4 etc. If you leave a line blank that would be considered end of multi line input. It uses my library Multi getvals.lsp to make the dcl. Some example code can be changed to work with a Dimension.

Look for Notepad your Acad.pgp make code even shorter. This the bat file I use. d: cd\alan\lisp findstr %1 *.lsp

You can private message me if you are after a custom program.

Hi everyone When I open a dwg file and use the attached lisp to change the Qleader settings, no changes are made to the settings. Please fix the problem for me. qlset.lsp.lsp test.dwg
