texts containing control codes are deleted after selection... Reaction to the Command: (entget ex) ; error: invalid argument type: lentityp nil

to be or no tobe a trapezoid or rectangle.dwg @mhy3sx please check the new dwg , I made a new polyline by offset base and leg and now the lisp take it as a rectangle .

Just for the benefit of AutoCAD archaeologists who find this thread, some companies don't upgrade their software because their big clients don't upgrade. Yes, you can convert drawings when you send them out, but why take that extra step every single time you pass files? So you wind up with these clusters of late adopters, all looking at each other--"you go first" "no, you go first"--and putting off the ordeal of upgrading everyone, and every year it will become harder, until finally it's inevitable.

Thanks for the answer ! I tested DOL and it unfortunately doesn’t solve my case. That routine keeps the single longest object from the entire selection, but it doesn’t check whether objects are collinear and overlapping. In my drawings I often have a LINE and a PLINE that lie on the same line with partial overlap; draw order puts the shorter one on top, so OVERKILL keeps the short piece. What I need is: Work with LINE and LWPOLYLINE (straight segments). Group only collinear segments whose projections overlap (within a small tolerance). In each group, keep the longest and delete the shorter overlapping pieces. Do not touch segments that are merely end-to-end (no overlap). Ignore draw order. If anyone has a LISP that does this “overlap-aware, keep-longest” behavior, I’d really appreciate it

I am hoping that you might have a simple suggestion on how to restore my workspace toolbars configuration. Hopefully I won't have to uninstall/reinstall my AutoCAD and rebuild my workspace as I'm expecting to have to.

Yep, that's what it was! I realized that it was a third party add-on from a few years ago that didn't fit my needs; uninstalled through Windows. Thank you!

If you haven't solved it yet, there's another possibility: Replace '(setq en (ssname ss cnt))' with '(setq en (ssname ss cnt)) ex en)' Load the code and run it again. Then, type '(entget ex)' on the command line. If it returns the entity list, see if '(60 . 1)' appears anywhere.

Hi @p7q, If this what you want, you can try with this: (prompt "\nTo run a LISP type: DOL (DeleteOverlappingLines)") (princ) (defun c:DOL ( / ss len i ename_length_list ename ename_length) (setq ss (ssget (list (cons 0 "*LINE"))) len (sslength ss) i 0 ename_length_list (list) ) (while (< i len) (setq ename (ssname ss i) ename_length (getpropertyvalue ename "Length") ename_length_list (append ename_length_list (list (list ename ename_length))) i (1+ i) ) ) (setq ename_length_list (vl-sort ename_length_list (function (lambda (x1 x2) (< (cadr x1) (cadr x2))))) ename_length_list (vl-remove (last ename_length_list) ename_length_list) total_len (itoa (length ename_length_list)) ) (foreach x ename_length_list (entdel (car x)) ) (prompt (strcat "\nThe total number of deleted lines is " total_len "!")) (princ) ) and you will get something like this (picture 1). Note: you need to select group by group to get only line or polyline with the highest length. Best regards.

The issue is that in my case the longest object is underneath and the shorter one is on top in the draw order. When I run OVERKILL, it keeps the top-most object, which ends up deleting my longest segment. What I need is to always keep the longest overlapping segment (LINE or PLINE) and delete the shorter one, regardless of the draw order.

I haven't forgot you, I am just swamped at work right now.

How about some more information? TableBuilder sounds like some 3rd party add-on for AutoCAD. Maybe add some screen shots or something. You should be able to uninstall the TableBuilder through Windows.

Works in AutoCAD 2026. Try restarting AutoCAD, then a reset to defaults if that doesn't work.

There is an option in OVERKILL to combine co-linear objects that partially overlap. If that's not what you need, post a before/after .dwg.

Hi everyono, I’ve tried using the OVERKILL command in AutoCAD to remove overlapping objects. However, it doesn’t have a parameter to keep only the longest object when there are overlaps. I’m looking for an AutoLISP routine that can work with LINE and PLINE (polylines), detect overlapping or collinear segments, and delete all but the longest one in each group. Thanks in advance!

Hi sir, @BIGAL It's a late reply but I try to figure out the ways as you said. I just simply made a seperate command, instead reactor based approach. That is too complicated and I'm not that much expert. I have used seperate commands to update linked texts. Now I'm trying to use this on multiple sessions while open/close and reopen the DWG file. But i couldn't fix that. Kindly help with update. Also could possible to link the attribute, block inside text contents?.

It was working OK for me in your sample drawing - I am using 2022 though but would expect any changes in 2021 to be carried through to that. Looking at the LISP, there is nothing in there to delete any texts, try loading it last in case there is another LISP loaded with the same name as some of the sub routines and try again maybe

In Autocad 2015, the code worked correctly, in Autocad 2021, texts containing control codes are deleted after selection... Unformat not work in Autocad 2021.dwg

What I posted is for Acad, Bricscad etc. Not sure if Inventor has a TXTEXP, some one will comment.

You should post a sample drawing.

@mhy3sx it calculate a2 as a trapezoid , because it is not a rectangle , short side are not parallel to be or no tobe a trapezoid.dwg

Hello! I am working in AutoCAD 2007/2008 and opened my AutoCAD this morning to find myself stuck in the TableBuilder screen which is odd because I never use TableBuilder. Anyway, can someone please help me leave the TableBuilder screen and return to my home screen where all of my tool icons reside? Thank you, Dave
