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.

Attempt number 2: This code is intended to always return a centerline whose points are all perfectly equidistant from the margins. This should happen in all cases where two LWPOLYLINEs are provided, one for each margin. The case of islands has not been considered yet. The resulting centerline is geometrically dense. This can probably be simplified in a future version. The approach taken in this code has been to obtain points from the normals and the bisectors of each margin, which are then combined at the end to build a list of points. Therefore, it is a fragmentary and massive approach. For this reason, the code is not very fast. However, there is another, more elegant approach, based on dynamically relating the geometry of both margins. It is more complex, but it would also be faster, and the error margins would be “bridgable”. If this thread has enough life in it, I may feel sufficiently motivated to finish it. That’s all for now. ;|*********************** CENTER-LINE ************************* ************************ G L A V C V S ************************* ************************** F E C I T *************************** |; (defun c:CLG (/ PI/2 lst e1 e2 l1 l2 lp lp1 lp2 p0 p> p< r1? x m a tol autoInt? ordenaPts interCpta ptEqd) (defun autoInt?

Their IT department even has a slogan (and I'm not kidding here) : You name it , we block it

The reason I clean the drawing is I once wrote a program to generate instrument loop diagrams from an excel file. I found the most stable and easy way was not to use a script but stay in the current drawing and from there save(as) each loop. I also made use from templates and also had the option to update the drawing in stead of generating the entire drawing. But at some time some templates had been given an update to a block definition and to be certain the latest version was used I had to make sure the old block was purged. Overkill , some times yes , but in my case it worked as it should. In this case , dxfin , probably overkill , but it doesn't hurt either. I tested it on Bricad 22 and the dwg extension was no problem, it worked as it should. The recommendation from the annoying paperclip oh , sorry , AI its called these days , to pimp the filename and use vla-saveas is not wrong though. Just didn't need it on my computer. Had it gave me an error I would have fixed it but it worked right from the start for me.

Obviously, this has now become something more than just the search for a solution to a single user’s problem. First of all, I should say that I myself was also reluctant to accept the concept of equidistance advocated by @GP_ and @dexus For the simple reason that applying this principle forced me to accept that the centerline should be the same in these two drawings. Equidistance requires ignoring those areas of the margins that do not geometrically affect the axis. This, which initially caused me some resistance, I eventually came to accept conceptually when I realized that it could serve as a criterion for defining what is a “recodo/inlet” and what is not. So I have abandoned my previous approach and adapted it to this new situation. Having made this clarification, I must say that this concept of equidistance makes the calculation of a centerline more feasible. I’ve been running some tests with Dexus’s latest code, which is the best so far. However, I’ve discovered some “holes” that I hadn’t noticed before. I’m attaching a few images showing this. In my view, these are conceptual errors rather than geometric limitations. And what can we consider “geometric limitations”? I believe that, in any case, every vertex of the centerline must be equidistant from both margins. If this is not the case, the result is not correct. However, the intermediate regions along each segment may be subject to geometric limitations depending on the desired precision. Therefore, in bends or turns, the points taken within the adjustment or “problematic” segments may deviate (within a tolerance) from strict equidistance. The goal, therefore (in my opinion), should be to achieve equidistance at every vertex and to remain within a tolerance in the intermediate zone of each segment. After everything written here so far, some might wonder: is it really possible to obtain a centerline that meets these requirements? As far as I’m concerned, I’m running some tests. GusanoAcad.mp4 I’ll post something over the weekend

I'll this topic a "wrap" Thanks to all here! rlx: I also have worked at my last company of fifteen years within a very locked down IT environment. Here and now, I am free! One caveat here is that there are limitations in acquiring additional Microsoft tools i.e., Power Platform tools, etc. due to the complexity introduced from being a client of an widely known commercial web hosting service. Happy, happy, happy! Clint

Use this and simply switch: *dist* (- *dist*) To: (- *dist*) *dist*

@Danielm103 ""with mtext, you have to use a fixed width font" I agree, Monotxt.sHx I think was what I used. monotxt_.ttf EXTRA FONTS A-Z.txt Banner heading3.lsp

I think with those big side offshoots you need to break the river into multiple plines so you would have two or more centrelines lines in that situation. As suggested by @SLW210 The problem will be how to work out the break offset shape.. Ps image dummied up.

This should achieve the desired result without overriding nested width formatting - (defun c:mtw ( / enx idx sel str wid ) (initget 6) (cond ( (not (setq wid (getreal "\nSpecify new width factor: ")))) ( (setq sel (ssget "_:L" '((0 . "MTEXT")))) (repeat (setq idx (sslength sel)) (setq idx (1- idx) enx (entget (ssname sel idx)) str (assoc 1 enx) ) (entmod (subst (cons 1 (addupdatewidth (cdr str) wid)) str enx)) ) ) ) (princ) ) (defun addupdatewidth ( str wid / ps1 ps2 ps3 ) (cond ( (= "" str) str) ( (and (setq ps1 (vl-string-search "{\\W" str)) (setq ps2 (vl-string-search ";" str ps1)) (setq ps3 (vl-string-search "}" str ps2)) ) (strcat (addupdatewidth (substr str 1 ps1) wid) (substr str (1+ ps1) 3) (rtos wid 2) (substr str (1+ ps2) (- ps3 ps2 -1)) (addupdatewidth (substr str (+ ps3 2)) wid) ) ) ( (strcat "{\\W" (rtos wid 2) ";" str "}")) ) ) (princ)

I think the real-world situation may be more complex than what we’ve seen here so far. I took a look at the links that @SLW210 attached and decided to test the Lisp codes proposed up to this point. I looked through my drawings for something that could serve as an example for this problem, but it was like looking for a needle in a haystack. So, in the end, I decided to look for something in the real world that clearly corresponds to this issue — something like this: So I drew those margins and tested all the codes that have appeared in this thread so far. The result was… this! In the drawing, you can see the ones that managed to reach the end. However, the codes by BIGAL, GP_, GLAVCVS, and MarkoRibar couldn't even do that. Here’s the drawing AxisExple4.dwg

Just use: (command "_.OFFSET" dist ent "_non" offsetpt "") And you no longer need to worry about OSMODE.

You would still need Visual Studio or similar and packages installed. Even for Visual Studio Code and LISP, I get PowerShell errors due to IT blocking it as well as the need to download the extension. Main issue is just lazy IT departments not wanting to due proper security, every issue I have had a work shows "improper server configuration" and/or "improper firewall configuration" when searching the issue. Anyone using Autodesk products (maybe other programs as well) has to manually override the proxy server on each restart of their computer or we have licensing issues. I had to to do all of the leg work on getting that issue resolved. Unfortunately that's just how many IT "professionals" are trained, "when in doubt, block it out". I normally don't have issues getting programs installed, just usually they are in no hurry to get it done. Autodesk is partly to blame, should be a better way to get apps, add-ons, etc. than needing an IT install. Even Microsoft, why do I need to update Windows and MS Office tools separately and need IT to allow use of PowerShell? To be honest though, I am just the AutoCAD guy, so they don't understand how programming with other tools is relevant.

If you want to change the offset direction, you just need to change the 'i?' parameter used to call 'sDir' from 'nil' to 'T' (as indicated in the code comment). Nikon2.mp4 PS: The video shows the execution of the code with 'i?' set to 'T'.

I tested the code on your drawing and it works correctly. Perhaps you didn't use it correctly. Nikon1.mp4

Yikes! Working with your arms tied.. No way I could work effectively without my tools, I would at least need autohotkey. Last company I worked for, I automated their whole system, mostly because I was lazy and I wanted to eat donuts all day. AutoCAD ships with .NET, nothing to install, I would be rolling some goodies for sure. “We At ACME corporation stifle innovation by making everyone think inside the box”

For most things I do this is my default option, rarely need to do much other than that and if I do, drag and drop.

Most of the members here have real jobs as well and provide help as their own busy schedules allow. I do not believe anyone was being rude, just nudging you along to do a little work for yourself.

Thank you all for the replies. Lee & Tsuky, Your code works perfectly for me. Steven P, thanks for explaining what was happening under the hood, made perfect sense. As always, I appreciate it greatly!!

Hi @PGia, wow, you managed to find another example that fails. Good stress testing! The reason mine fails is because it ignores the offset lines that are split in two or more parts. But some of the parts are still be usable and should be used. I looked into fixing this and managed to add those lines, but this resulted in some other problems so I didn't update the code on the earlier post yet. The zigzag problem is coming back on your example. The result below. I really need to find a solution for that, but it looks like I might have to use a path finding algorithm which would slow down the code a lot. Sorting the points by distance on the offset line is not enough anymore.

Yes ! Your first step is get a copy of lee-mac dynamic block properties.lsp. I like others have used his code with great success. You may need to get all property names first, so you can then get in turn that property value, eg "Distance1", the current visibility state is much easier to get. If you get stuck just post again. https://www.lee-mac.com/dynamicblockfunctions.html

Just a follow up. I posted that long before I knew the importance of making sure that the Author of the code is noted as well as where I found the code. All credit goes to Gilles Chanteau. I have no idea where I found that code... It is probably somewhere here on cadtutor. I have since, started making sure that ifo is included as a header in the file, that way it doesn't look like I am trying to take claim for it and also, if/when something stops working I know where to go to address the issue. ~Greg original posting of code: https://www.theswamp.org/index.php?topic=29339.msg350137#msg350137

Obviously we don't have your batch LISP - I guess your company paid for this and so you are not going to be popular sharing that for all online. LISPs can be added to scripts - both as a command and as code. There are others out there such as ScriptPro and Lee Macs Script Writer which will do this. BigAl will often post snippets of scripts here to batch process files - last one he did was in the last week or so ago. You could even set this up as a stand alone script to do just the one task (see BigAls last example....) The first step for all is to get a LISP working as you want and well on a single file and then to do it as a batch (first time running the batch with a new LISP, perhaps check carefully that it doesn't do anything unexpected on other files). Plenty of examples out there to change layer names from one to another - have a look to see if you see one you like to use, or if there isn't am sure we can put one together - and use what is above as a started if you want to have a go, I think all the code you need is in the examples, just need to think how to change them to your needs

Good day everyone! I've discovered new (old?) the possibilities of a true rectangle. It is very convenient to work with him! The only drawback is that the rectangle is unstable. You can create it and work with it only in the current file. If you then close and open this file, the properties of the true rectangle are lost. Is it possible to make it stable so that its properties are preserved? https://autocadtips1.com/2011/11/20/autolisp-make-a-real-rectacgle/ AutoLISP: Make a Real Rectangle Posted on November 20, 2011 by AutoCAD Tips A long time ago, AutoCAD used to make Rectangles and polygons as their own entities. When you made a rectangle and then did a LIST <enter> on it, it would show as a rectangle. Nowadays, these objects are those objects in their geometry but are made of polyline entities. So modifying these objects is sometimes hard. that’s where this routine steps in to help. This routine lets you create a rectangle and even after you continue working elsewhere in your drawing, you can come back to that rectangle and modify that object and it acts like how rectangles used to act in AutoCAD. Here’s how: TREC <enter> to start “True RECtangle” Create a rectangle how you normally create one When needed, this routine will let you drag a single corner and the rest of the rectangle’s geometry will adjust accordingly to keep its geometry as a rectangle. TrueRect.lsp

Based on the title of your thread, here's an existing program to match dynamic block properties: https://www.theswamp.org/index.php?topic=44444.msg496892#msg496892 Where mirroring text in blocks is concerned, here's some food for thought: https://www.theswamp.org/index.php?topic=46271.msg513250#msg513250

Don't use CIV3D much anymore but there is the command IMPORTSTYLES if I have the command name correct can choose what is imported from another dwg.

@Nikon Like I said - "For What It's Worth". Note also you can shorten the steps slightly by using the PERP object snap.

@Nikon FWIW - you can use the midpoint grips to drag the rectangle in straight directions to keep it square.

It can be done, but it requires creating a custom object using ObjectARX (C++).

Ugh I think I watched your video too fast. I haven't had much time to do anything slowly lately I believe object reactors only survive the current drawing session. You must consider that the reactor was created relative to an object name, and object names change between drawing sessions.

Inside the "initget" you use "Screening_50.ctb Fill_Patterns.ctb" with "_", and inside the "getkword" you use "Screening 50%.ctb/Fill Patterns.ctb", which is not equal as it in "initget". Everything must be equal. So, according from your's "initget", the "_" can't be in use, because it's in use for localization (for eg. "_RECTANG", "_LINE", etc.). From this link you can find this: Keyword Specifications The string argument is interpreted according to the following rules: 1. Each keyword is separated from the following keyword by one or more spaces. For example, "Width Height Depth" defines three keywords. 2. Each keyword can contain only letters, numbers, and hyphens (-). One of the possible solutions is to use this: (initget 1 "Monochrome.ctb acad.ctb Grayscale.ctb Screening50.ctb FillPatterns.ctb") (setq plotstyle (getkword "\nChoose plot style [Monochrome.ctb/acad.ctb/Grayscale.ctb/Screening50.ctb/FillPatterns.ctb] <Monochrome.ctb>:")) (cond ((equal plotstyle "Screening50.ctb") (setq plotstyle "Screening_50.ctb") ) ((equal plotstyle "FillPatterns.ctb") (setq plotstyle "Fill_Patterns.ctb") ) ) Best regards.

Python, makes Batch processing a bit easier sometimes import traceback from pyrx import Ap, Db def capcaseLayers(db: Db.Database): lt = Db.LayerTable(db.layerTableId()) for name, id in lt.toDict().items(): l = Db.LayerTableRecord(id, Db.OpenMode.kForWrite) l.setName(name.upper()) def processDb(fpath: str): sdb = Db.Database(False, True) sdb.readDwgFile(fpath) sdb.closeInput(True) capcaseLayers(sdb) sdb.saveAs(fpath) #add new command @Ap.Command() def caplayers(): try: for fpath in Ap.Application.listFilesInPath("E:\\temp", ".dwg"): processDb(fpath) except Exception as err: traceback.print_exception(err)

The PIP is here ‘pip install cad-pyrx’ https://pypi.org/project/cad-pyrx/, the project is here https://github.com/CEXT-Dan/PyRx It’s an amalgamation of BRX and ActiveX APIs. There’s some stuff for BIM as well.

Like @rlx this is a hard coded plot pdf using preset values, our dwg's used layouts one title block. the code is hard coded for a A1 sheet plotted as a A3 size. We just walked through the layouts and plotted. So does not matter what current plot settings are as they are ignored. We had multiple devices PDF, A1, A3 Color, A3 B-W. So code for each. (setvar "textfill" 1) (setvar "fillmode" 1) (COMMAND "-PLOT" "Y" "" "Plot To PDF" "Iso full bleed A3 (420.00 x 297.00 MM)" "m" "LANDSCAPE" "N" "W" "-6,-6" "807,560" "1=2" "C" "y" "Acad.ctb" "Y" "n" "n" "n" pdfName "N" "y" )

maybe just something simple as : (setvar "filedia" 0) (command ".-plot" "No" "" "" "" (strcat (getvar 'dwgprefix) (getvar 'ctab) ".pdf") "No" "Yes") (setvar "filedia" 1)
