I did some more tests today and found that when the end segments were parallel, they didn't get added to the line. So I added support for that. This one was easy because the _cornerOffset function already checks for parallel segments and I just had to add a flag to inform the offset loop. And I found another example which it has a hard time on with concentric arcs, attached below. But that will be for another day since I have no more time for that this week. AxisExple3.dxf

Hi everyone, I’ve been working on a small production tool in AutoLISP/VLISP for AutoCAD / Civil 3D and thought it might be useful to share here for anyone doing a lot of section or profile sheets. ## What problem it solves On corridor / section jobs we often end up with several paper-space viewports that all need to: - Use the same scale and twist - Stay aligned to a centerline / path (alignment, guide polyline, etc.) - Be re-centered after design changes The usual manual workflow for us was: 1. Set up one “master” viewport with the correct scale, twist, layers, etc. 2. Copy that viewport across the layout for each station/section. 3. Manually PAN/ZOOM/DVIEW in each viewport to center the correct station along the path. 4. Repeat that pan/zoom step any time the design or alignment changed. It works, but it’s tedious and easy to make mistakes when you have a lot of sheets. ## What SectionSync LITE does SectionSync LITE is a compiled VLX that: - Lets you pick a polyline path (e.g. alignment, section chain, etc.) - Associates multiple paper-space viewports with positions along that path - Updates the view center of each viewport so it “follows” the path - Preserves the existing viewport scale and twist - Can be re-run after design changes so you don’t have to manually re-pan everything It was written mainly with Civil 3D section/profile sheets in mind, but it’s just working with standard AutoCAD viewports and a polyline. ## Technical notes - Written in AutoLISP/Visual LISP and compiled to VLX for distribution. - Uses vla/vlax functions to read and set viewport center, width/height, and twist. - Path positions are based on cumulative distance along the selected polyline. - No reactors or custom objects – it just runs on demand and updates existing VPs. ## Demo + download Short demo video: https://youtu.be/l1JRbz4_owQ Download / more details (there’s a built-in 5-run / 7-day trial so you can test it on a real project): https://autolispwizard.gumroad.com/l/civabs If anyone is interested in the implementation details (polyline parameterization, handling UCS and VP twist, etc.) I’m happy to discuss approaches or share pseudo-code for the core parts.

mhupp, I want AutoLISP code to do that.

Great! Thanx! It did gave me an error after the first page so I changed one of your subs a little. added this line : (and blkRef (vlax-method-applicable-p blkRef 'Name)) (defun set-block-contents-color (blkRef layer color / blkDef) (if (and blkRef (vlax-method-applicable-p blkRef 'Name)) (progn (setq blkDef (vla-item (vla-get-Blocks doc) (vla-get-Name blkRef))) (vlax-for ent blkDef (vl-catch-all-apply 'vla-put-layer (list ent layer)) (vl-catch-all-apply 'vla-put-color (list ent color)) ) ) ) )

AutoCAD is very bad at running a LISP in one file to read another file, it is not something I have looked at with xrefs, however this might give you a starter, listing any xrefs in the current file - I was looking at this to do something different and is in the folder "finish this one day"... so the code might not be 100%. ;;https://forums.autodesk.com/t5/visual-lisp-autolisp-and-general/grab-all-xref-names-and-paths/td-p/1661552 ;;(defun filepfil ( / Doc LayoutCol EndList) ;; Returns a list of list of all the Xrefs and Images with their paths within a drawing.

Use CLASSICXREF will display a window for you to look thought. for the ones that you suspect to be circular switch to overlay.

Using Bricscad dwg has a solid, finds trace. Or do you mean (setq ss (ssget "_X" (list (cons -4 "<NOT") (cons 0 "3DSOLID,TRACE") (cons -4 "NOT>")(cons 410 (getvar 'ctab)))))

@mhupp this may be useful, it captures command errors so after loading your lisp. You type say p2-3 on command line. Can do say p1-2, Pr3-2, prec1-0 and so on. ; test trap a command used as variable input ; BY Alan H 2019 ; now 2025 ( (lambda nil (vl-load-com) (foreach obj (cdar (vlr-reactors :vlr-command-reactor)) (if (= "fillet-reactor" (vlr-data obj)) (vlr-remove obj) ) ) (vlr-command-reactor "fillet-reactor" '((:vlr-unknowncommand . fillet-reactor-callback))) ) ) (defun fillet-reactor-callback ( obj com ) (setq com (car com)) (alert com) ; do the split com into ; (Change_Prec X X)) ) ; defun (or fillet-reactor-acdoc (setq fillet-reactor-acdoc (vla-get-activedocument (vlax-get-acad-object))) ) Thinking more maybe only check p12, prec10

K updated my code as well. tho this seems to not work well with BricsCAD. moved the vlax-put to only update when the if statment is true. change_prec_fields_update.lsp

I've modified my latest code to introduce current precision and search in the Mtext

@Saxlle just a comment a bit hard to see what is going on in video maybe use a screen area rather than full screen. Win 11, Shit+Window+R allows screen area record. Drag window area then start / stop. This may be useful rather than a list box can tick one or all choices, add an All option so one click. Examples in code. Multi toggles.lsp

(ssget "_X" (list (cons 0 "~3DSOLID")))

And with this syntax? (sssetfirst nil (ssget "_X" '((0 . "*") (-4 . "<NOT") (0 . "3DSOLID") (-4 . "NOT>"))))

Nice test @PGia, thanks! For some reason I didnt consider closed polylines in the _checkOffset function, so I added an extra check there. Should work as expected now: Not sure about the short corner. The lines are so narrow the centerline is pushed back out of the point. Seems to be logical to me but it does feel intuitive. Narrow indents don't get much love from the centerline. So "inlets" don't have enough influence on the shape of the line. What would the expected result be? Below makes sense since there is not enough space to go into the indent. Or are you maybe something like this where the line splits and goes into the hole:

Maybe this kind of solution can be interesting (to use a multiple selection, use Shift+Left mouse click, to use a single selection, use CTRL+Left mouse click): ; ************************************************************************** ; Functions : CHRENLAYERS ; Description : Select Layers To Change It To UPPERCASE Or LOWERCASE ; Author : SAXLLE ; Date : December 04, 2025 ; ************************************************************************** (prompt "\nSelect Layers To Change It To UPPERCASE Or LOWERCASE!\nTo run a LISP type: CHRENLAYERS") (princ) (defun c:CHRENLAYERS ( / old_echo dcl_id fname fn laylist lay items rval acad name) (vl-load-com) (setq old_echo (getvar 'cmdecho)) (setvar 'cmdecho 0) (create_dialog) (collect_layers) (setq dcl_id (load_dialog fname)) (if (not (new_dialog "Laylist" dcl_id)) (exit) ) (action_tile "cancel" "(cancel)") (start_list "ls") (mapcar 'add_list laylist) (end_list) (action_tile "ps1" "(read_items) (to_uppercase)") (action_tile "ps2" "(read_items) (to_lowercase)") (start_dialog) (unload_dialog dcl_id) (vl-file-delete fname) (gc) (princ) ) (defun cancel () (done_dialog 0) (terpri) (prompt "Application running were finished...")

Have a look at (setq lays (layoutlist)) there is no Model in the list created saves a few if and buts. Can use also (setvar 'ctab "Model") so no Doc required.
