Greetings to all members of Cad Tutor, Based on the upcoming holidays and New Year, I'v made something interesting which I want it to share with you. Everything was made using a Lisp. I hope it will interesting to all of you and maybe give some inspiration to the next year to made something different and share it with rest of us . Notice (it is on cyrillic, in Serbian language): - ЗИМСКА СЛУЖБА = Winter service on roads; - СРЕЋНА НОВА ГОДИНА = HAPPY NEW YEAR; - XO-XO-XOO = HO-HO-HOO (). Happy New Year 2026 to all members, and wish you all the best and new codes . NovaGodina2026_CadTutor.mp4 Best regards, Saxlle.

@mhupp do you want a lisp version of that ? It works same way uses "*". I think it was 1990.s used it as header in lisp programs.

My 0.02¢ sprinkle some code in updates a variable through out the code. and recall it with error trapping This will show Error# 4 : bad argument type <(40)> ; expected <NUMBER> at [DXF/XED data] this error message would tell you to look after (setq x "4") for the error. (defun c:CIR (/ cen rad) (defun *error* (msg) (if (not (member msg '( "Function cancelled" "quit / exit abort"))) (princ (strcat "\nError# " x " : " msg)) ) (princ) ) (setq x "1") (setq cen (getpoint "\nSpecify center point: ")) (setq x "2") (if cen (progn (setq x "3") (setq rad (getdist cen "\nSpecify radius: ")) (setq x "4") (if rad (entmake (list '(0 . "CIRCLE") '(100 . "AcDbEntity") '(100 . "AcDbCircle") (cons 10 cen) (cons 40 ra))) ) (setq x "5") ) ) (setq x "6") (princ) ) -edit guess this is more steps then what Steven P posted. Also remember someone saying that zwcad can't use some vl commands.

Like Steven P often use an Alert so it stops and can see where it got to. I tend to test code as I make it so I don't write all the code then test, If using defuns in main code test them by using Setq to set the value of the variables used in the defun and I use copy code and paste to command line to run a few lines at a time. The obvious problem I use Notepad++, is check for open and close bracket matching as I create code. I think it was ZWCAD that wrote VBA code when using macro record am I correct ?

A couple of LISPs, PurgeZeroLengths and PurgeZeroTexts: Note that purgezerolengths has a 'less than a length' for very short lines, here set at 0.01 - comment that out with ;; at the beginning of the line if not needed. These remove orphaned lines and texts. Copy and paste to a new drawing (top left -> bottom right seletion) or wblock does a lot. If not needed delete points - don't show up on the printed page, and if not needed get rid. Bit more effort but using blocks for repeated objects can remove some bloating. If you don't need them to be polylines, explode 2 vertex polylines into lines (2nd LISP box below). Explode heavy polylines into LW polylines of you can, both smaller file sizes One I have tucked away, join perpendicular lines back together - example convert from PDF, dashes are individual lines, this will go some way to recreating them as lines - run after 2 vertex poly to line (3rd LISP box, not perfect, only does H or V lines) (defun c:PurgeZeroLengths ( / MySS DelSS MyEnt EndA EndB) ;; for within blocks (setq MySS (ssget (list (cons 0 "LINE,SPLINE,LWPOLYLINE,POLYLINE,ARC,CIRCLE,ELLIPSE")))) (setq acount 0) (setq DelSS (ssadd)) (while (< acount (sslength MySS)) (setq MyEnt (ssname MySS acount)) (if (equal (vlax-curve-getDistAtParam MyEnt (vlax-curve-getEndParam MyEnt)) 0) (progn (setq DelSS (ssadd MyEnt DelSS)) ) ) ; end if ;;If less then a length (if (< (vlax-curve-getDistAtParam MyEnt (vlax-curve-getEndParam MyEnt)) 0.01) (progn (setq DelSS (ssadd MyEnt DelSS)) ) ) ; end if (setq acount (+ acount 1)) ) ; end while (princ "\nDeleting ")(princ (sslength DelSS))(princ " lines") (command "erase" DelSS "") (princ) ) (defun c:PurgeZeroTexts ( / MySS DelSS MyEnt MyText) ;; for within blocks (setq MySS (ssget (list (cons 0 "*TEXT")(cons 1 "")))) (setq acount 0) (setq DelSS (ssadd)) (if MySS (progn (while (< acount (sslength MySS)) (setq MyEnt (ssname MySS acount)) (setq MyText (cdr (assoc 1 (entget MyEnt)))) (if (equal MyText "") (progn (setq DelSS (ssadd MyEnt DelSS)) ) ) ; end if (setq acount (+ acount 1)) ) ; end while (princ "\nDeleting ")(princ (sslength DelSS))(princ " lines") (command "erase" DelSS "") ) ; end progn (progn (princ "No zero content texts found") ) ) ; end if (princ) ) (defun c:pdfDashed2PL ( / MyEnt MySS EndA EndB LEndA LEndB Orientation acount EndPoints LineLengths) ;; Selects by layer and colour (defun LoadLineType (doc LineTypeName FileName) ;;https://www.cadtutor.net/forum/topic/76557-load-linetypes-from-lisphelp/ (if (and (not (existLinetype doc LineTypeName)) (vl-catch-all-error-p (vl-catch-all-apply 'vla-load (list (vla-get-Linetypes doc) LineTypeName FileName) )) ; end vl-catch ) ; end and nil T ) ; end if ) ; end defun (defun existLinetype (doc LineTypeName / item loaded) (vlax-for item (vla-get-linetypes doc) (if (= (strcase (vla-get-name item)) (strcase LineTypeName)) (setq loaded T) ) ) ) (setq thisdrawing (vla-get-activedocument (vlax-get-acad-object))) (vla-startundomark thisdrawing) ;;Load Line Types (LoadLineType ThisDrawing "Dashed" "acad.lin") (LoadLineType ThisDrawing "Center" "acad.lin") ;;Select Reference Line (while (= MyEnt nil) (setq MyLine (car (entsel "\nSelect reference Line"))) (if (= MyLine nil) (princ "\nPity the fool, nothing selected.
