Some state utilities also require a specific, legacy version (Florida Power & Light, as example), so the export back is required if we want construction approval. To expedite that task, I created a Windows Shell (aka context) menu so we can simply right click --> export DWG base files from file explorer using Core Console, then send. This Shell menu (and others) gets updated as we roll out new Autodesk product versions. Cheers

the problem is that is not regognise the wrong polyogn. I prefear to do the updates to this code. This is the Mtext i want to export, nothing else.

We are thrilled to announce that AutoCAD 2026.1 and AutoCAD LT 2026.1 are now available, packed with exciting new features and enhancements designed to make your design experience more productive and collaborative. At Autodesk, we constantly strive to innovate and improve our tools based on user feedback, and these new 2026.1 releases are a testament to this commitment. We’ve made several significant updates to features that you’ll want to check out. If you’re already eager to dive into these new capabilities that AutoCAD has to offer, go ahead and open the Autodesk Access application to start your update while you read this post. Note: The 2026.1 update is automatically included in every new installation of AutoCAD 2026. Multi-User Markup – Desktop Integration One of the most significant enhancements in AutoCAD 2026.1 is the integration of Multi-User Markups within the desktop application, which allows multiple users to add markups to a single design to facilitate seamless collaboration. You can now access and incorporate markups created in AutoCAD on the web into your desktop workspace, ensuring that feedback and collaborative efforts are consolidated in one place. With AutoCAD 2026.1, these markups, made with the advanced yet easy-to-use markup tools now available via AutoCAD on the web, can now be accessed directly in the desktop application. As a refresher: multi-user markups allow you to streamline collaboration on Autodesk Docs projects by giving you the ability to collect and share feedback directly on drawings using intuitive Autodesk Docs markup tools. Although these markup tools are originally from Autodesk Docs, they are now available on AutoCAD on the web and accessible through the desktop application. In addition, the new SHARE command allows you to share DWGs stored on Docs for markup in web only, furthering the level of control you have in collaborative environments. TRACE layers enable users to markup files that continuously sync, providing flexibility for teams to review and markup changes together. This collaborative approach enables all feedback to be captured and addressed, leading to better project outcomes. This integration means that collaboration will now be much more productive, making it easier to incorporate changes and suggestions from multiple stakeholders, all while working within the familiar desktop environment. Merging “Learning” and “My Insights” Tab in App Home In AutoCAD 2026.1, the “Learning” and “My Insights” tabs have been combined into one convenient section in the App Home interface. This update eliminates the need to navigate between separate tabs, consolidating all the tutorials, tips, and personalized insights into a single, easy-to-access location. By merging these tabs, it provides a more cohesive and efficient experience. The streamlined layout simplifies navigation and reduces clutter, allowing you to quickly find valuable resources and customized insights tailored to your unique usage patterns. Whether you’re a seasoned professional or new to AutoCAD, this enhancement combines all efficiency and learning tools into one place, ensuring that you have a one-stop shop for boosting your AutoCAD efficiency. Smart Blocks UX Refinements Smart Blocks remains one of the most popular features in AutoCAD. With the 2026.1 update, we’ve made significant UX refinements to enhance its functionality. These refinements include an improved design and user interface, allowing you to create and manage Smart Blocks with greater ease. Detection Progress Indicator This new feature gives real-time updates on the status of block detection processes, allowing you to easily monitor and anticipate the completion of block detection operations. This enhancement increases transparency, enabling a more fluent and controlled workflow so you’ll know where you’re at in the process. Tooltips for Detection Actions New tooltips provide quick and informative hints regarding various detection tasks, enabling you to understand functionalities right in the product without needing to refer to external documentation. The addition of these tooltips contributes to reducing the learning curve, making Smart Blocks more approachable for both new and experienced users. New Option for Layer Assignment AutoCAD 2026.1 introduces a new option to assign block definition objects directly to layer 0. This enhancement simplifies the layer assignment process, ensuring that block definitions are organized efficiently and consistently. By assigning objects to layer 0, you can benefit from enhanced control over visibility and plot styles, leading to cleaner and more manageable drawings. These enhancements are focused on usability and performance, ensuring that you can work more efficiently. The refined UX makes it simpler to manipulate and deploy Smart Blocks within your designs, ultimately saving you time and reducing the effort needed for repetitive tasks. Seven New Productivity Enhancements AutoCAD 2026.1 now includes seven new productivity enhancements that address user pain points and significantly improve the overall user experience. Each of these new enhancements has been carefully designed to boost your productivity and satisfaction with AutoCAD. Here is a list of the included improvements. Please refer to the 2026.1 Help documentation for complete details. New VIEWPORTLAYER System Variable New REVCLOUDLAYER System Variable New TABLELAYER System Variable Increased the maximum number of active viewports Warm grip dynamic menu shortcut support REVCLOUD Arc length setting is no longer adjusted for new DIMSCALE Find and replace now works with multiline texts having “\P” line breaks Update to AutoCAD 2026.1 and AutoCAD LT 2026.1 Today If you already started your update at the beginning of this post, you should be one step closer to experiencing these features first-hand—if not, what are you waiting for?

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

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.

Thanks

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
