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.

I'm interested in where this topic will be going with the different "side quests" like islands and inlets. In the mean time I kept going, trying to fix my version and after a lot of testing/debugging I changed to code again. Now it is working as expected on all of the examples I have found! ;| ; Calculate centerline between two polylines - dexus ; Function checks intersections of the offsets of two lines to create a middle/avarage line. ; https://www.cadtutor.net/forum/topic/98778-hybrid-parallel/page/7/#findComment-677877 ; Version / Date - Change ; 0.01 [19-11-2025] - Initial release ; 0.02 [27-11-2025] - Added corner support on negative side of crossing polylines ; 0.03 [28-11-2025] - Extra check using vertex to closest point as distance ; 0.04 [28-11-2025] - Added error function ; 0.05 [01-12-2025] - Improved distance check to prevent zigzag lines ; 0.06 [01-12-2025] - Check if offset can be used before adding points ; 0.07 [01-12-2025] - Improved side check on 3 points ; 0.08 [04-12-2025] - Don't compare startpoint to offset when eiter of the polylines is closed ; 0.09 [05-12-2025] - Add points for parallel end segments ; 0.10 [18-12-2025] - More checks for deleting lines and added dedicated function ; 0.11 [08-01-2026] - Support for multiple output lines of the offset function ; 0.12 [08-01-2026] - Bulges are transformed to lines to handle cocentric arcs ; 0.13 [08-01-2026] - Rewrote the _avarageAngle and _diffAngle function |; (defun c:cl (/ corners ent1 ent2 gap index loop maxlen offset offsetdistance org1 org2 parallel pts sides ss start te0 te1 te2 tmp1 tmp2 LM:ProjectPointToLine LM:intersections _addPoints _avarageAngle _checkOffset _checkSortDirection _copyPolyline _cornerOffset _deleteTmpLine _diffAngle _doOffset _getAnglesAtParam _polyline _side *error*) (defun *error* (st) (if (wcmatch (strcase st t) "*break,*cancel*,*exit*") (redraw) (princ (strcat "\nOops!

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?

I don't really see the point of the dynamic mode in your function, especially if you want to snap to objects. This would seem to me to be sufficient and would resolve the osnap.

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.

I have a dump LISP called TakeADump, maybe I need this to go along with it!

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

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”

This is one I was looking at yesterday, sharing here because I am really 12.... 'WipeBottom' will move the defined entity types to the Bottom or Top draw order in a selected block definition. Define the entity types and move direction in the code. Made up because I wanted to split out the selection part of the examples online and use the 2nd part via LISP without user interface. Via LISP I only wanted it to process a single block at a time - selection set processing can be from the calling LISP. Examples out there mostly from Lee Mac - see his website or the link in the code. But apart from that I really wanted to use the LISP command name.

My first comment is when you hard print the pdf you have to pick a paper size so why would you not just pick a paper size to start with ? I do not understand the Custom scale size needed. In the world you are normally metric or imperial paper sizes. You can easily with a lisp etc plot a standard sheet size in a layout that has a Viewport at the correct scale. I think that is the step your not understanding, many example code does exist. For me a couple of choices make multiple layouts at scale walking along a pline, make multiple rectangs in Model at a scale matching viewports and title blocks in layouts. In this image select a title block and scale pick on Model and correct layout is made. A rectang is drawn in the model showing the result so you can accept or erase and run again. You can move and rotate the rectang before making the matching layout.

Must have deleted from my other post, But how grread works I don't know if you can use snaps. every time you move the mouse it updates the point and calculation. maybe Tsuky knows of a way.

The question was AutoCAD and was 12 years ago. To add, not much help just stating a program has a feature without any other context. Though there is the ability to adjust linetypes in MicroStation, the usual remedy is to break the line in most cases, same as AutoCAD.

Have you looked into fields? When you edit a text object, you can type Ctrl-F to bring up the fields dialog. Pick a category, such as Date & Time, and pick the data you want to insert. To match your example, choose Date and a format. That field will be inserted into the text, like any other characters, but highlighted and with the corresponding data. There are many more pieces of data you can use. Once you put fields into your template, you may never have to change a title block again.

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

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.

I post the 3d house image often and a version of that software was available for Intellicad back in the 90's, there was no VL lisp in those days. It was very good then and seen as a competitor to LT,

Some really cool stuff here

test with wxPython

Note that you can use my Layer Director to preset & reset a layer (including layer creation) for both standard and custom commands: https://lee-mac.com/layerdirector.html

A simple script made with notepad. Open dwg1.dxf qsave dwg1 close Open dwg2.dxf qsave dwg2 close Open dwg3.dxf qsave dwg3 close Open dwg3.dxf qsave dwg3 close The dwg1 would be like "C:\\mydxfiles\\project123\\dwg1" There are various ways to make a list of dwg names, how many are we talking about ?

Just use a point and insert Field in Mtext and format it how you want. When copying both point and text it will keep the new copied items linked. Regen to update the coordinates.

You can also use fields with selection of points? (defun make_field (ent / pt obj) (setq pt (trans (cdr (assoc 10 (entget ent))) 1 0)) (mapcar '(lambda (lx) (apply '(lambda (ins_point value_field att_point txt_height dwg_dir name_layer txt_rot / nw_obj) (setq nw_obj (vla-addMtext Space (vlax-3d-point (trans ins_point 1 0)) 0.0 (strcat "{\\f@Arial Unicode MS|b0|i0|c0|p34;\\Q15;" "%<\\AcObjProp.16.2 Object(%<\\_ObjId " (itoa (vla-get-ObjectID (vlax-ename->vla-object ent))) value_field "}" ) ) ) (mapcar '(lambda (pr val) (vlax-put nw_obj pr val) ) (list 'AttachmentPoint 'Height 'DrawingDirection 'InsertionPoint 'Layer 'Rotation) (list att_point txt_height dwg_dir ins_point name_layer txt_rot) ) ) lx ) ) (list (list (mapcar '+ (trans pt 1 0) (list (getvar "TEXTSIZE") (+ (* (getvar "TEXTSIZE") 1.25) (getvar "TEXTSIZE")) 0.0)) ">%).Coordinates \\f \"%lu2%pt1%pr3%ps[X:,]\">%" 4 (getvar "TEXTSIZE") 5 "Id-XY" rtx ) (list (mapcar '+ (trans pt 1 0) (list (getvar "TEXTSIZE") 0.0 0.0)) ">%).Coordinates \\f \"%lu2%pt2%pr3%ps[Y:,]\">%" 4 (getvar "TEXTSIZE") 5 "Id-XY" rtx ) (list (mapcar '- (trans pt 1 0) (list (- (getvar "TEXTSIZE")) (+ (* (getvar "TEXTSIZE") 1.25) (getvar "TEXTSIZE")) 0.0)) ">%).Coordinates \\f \"%lu2%pt4%pr3%ps[Z:,]\">%" 4 (getvar "TEXTSIZE") 5 "Id-Z" rtx ) ) ) ) (defun c:point-xyz_field ( / htx rtx AcDoc Space ncol ss n) (initget 6) (setq htx (getdist (getvar "VIEWCTR") (strcat "\nSpecify the height of the field <" (rtos (getvar "TEXTSIZE")) ">: "))) (if htx (setvar "TEXTSIZE" htx)) (if (not (setq rtx (getorient (getvar "VIEWCTR") "\nSpecify the orientation of the field <0.0>: "))) (setq rtx 0.0)) (vl-load-com) (setq AcDoc (vla-get-ActiveDocument (vlax-get-acad-object)) Space (if (= 1 (getvar "CVPORT")) (vla-get-PaperSpace AcDoc) (vla-get-ModelSpace AcDoc) ) ncol '(96 174) ) (foreach n '("Id-XY" "Id-Z") (cond ((null (tblsearch "LAYER" n)) (vlax-put (vla-add (vla-get-layers AcDoc) n) 'color (car ncol)) ) ) (setq ncol (cdr ncol)) ) (while (null (setq ss (ssget '((0 .

Yes. I know. I already mentioned that this problem could arise on some long segments during turns. I didn't want to delay posting again to fix this. But I already have an idea of how to solve it. I'll post the solution as soon as I can.

I tested the code. All the points are equidistant, but there are two long segments where the equidistance is drastically broken. In the last screenshot Dexus attached, you can see approximately where the center line should be in that area. The center line returned by the GLAVCVS code is shown in magenta. And the approximate location where it should be is shown in red. I've attached an image of this

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

When you are trying tricks like these AutoCAD is very fussy that you do things correctly, in your block there are no actions that match up with you linear parameters, there also needs to be an object selected for those actions, watch that second video you linked too at about the 5.30 minute position your parameters also need to be set as a list of defined measurements. This is a tricky subject to get the hang of, but well worth the effort. And a tip it is much easier to keep your linear parameters horizontal and stacked above each other as in that video it just makes it easier to see what is what and keep your actions organised as well.
