Hey @BIGAL, I used a "base point" to avoid determinanting is the polyline drawn CCW or CW, easier, and then calculated new position of the polylines based on choosing "Left or Right", which means the "X" coord will change in that side. Also, I supose that the polyline can have many vertexes and drawed randomly (not only straight lines). Bassicly, this is the one of the concept how it can be done. I figured out the easiest way is sorting by the Lengths of the polyline, from min to max, to get a proper order. Can't wait to see your solution, maybe find something interesting inside the code .

@Saxlle Thanks for the code. It’s working based on the concept. Please check the DWG file. I’ve worked on Option 1 and Option 2. In Option 1, I planned the left-side spacing as per your video input, all settings are done, but the output line looks different. Please advise on this. Option 2 is another concept where the top side moves up and down, similar to the left and right adjustments line shifting.dwg

Thought we were getting tolled when i saw @GP_ GIF had to double take on the original posted dwg.

Hi @Saxlle started to do something found the plines are drawn in a CCW or CW direction for left right so I am going to set that to one direction I look at the length of 1st and 3rd section to work out which end to change, so no need for Left or right. The start point is (/ offset 2) left or right. So don't need user enter base_point. I just worked out the new X values for the pline and use (vlax-put obj 'coordinates pts) to redo the pline no need to actually draw a new pline. use (vlax-get obj 'coordinates) for the XY values of the pline. Yes need a ssget but looking at a drag over the plines for offset order. So yes would do twice for sample. NOTE my code is based on the sample dwg provided, got about 1/2 way when posting this, hopefully later today will post my attempt.

If your trying to get the levels shown by the Brown lines color 11 you will end up with a mess of overlapping text. In this image looks like a road etc so want levels. Civ3D at times lacks some functionality, it looks like you have used a built in grid option for plotting long section etc. You may be better off going back to your CAD dealer and ask for help about how to set up CIV3D to meet your needs. I know in other add on software can use different methods to set what points get levels plotted, A lot of times the complexity of using CIV3D is a problem and finding the solution is difficult. Maybe post this question into the CIV3D forum. I stopped using CIV3D many years ago so can not help.

The issue wasn't retention of the stacking. In version 5.0c at least the height checkbox didn't remove the text overide whilst the copy of 5.0d I found did.

replace ;;----------------------------------------------------------------------;; (vl-every '(lambda ( sym msg ) (initget 6) (set sym (getdist msg))) '(ard crd erd aof eof) '("\nSpecify approach radius: " "\nSpecify center radius: " "\nSpecify end radius: " "\nSpecify approach offset: " "\nSpecify tie-in offset: " ) ) ;;----------------------------------------------------------------------;; with ;;----------------------------------------------------------------------;; (setq crd (getdist "\nMiddle Radius: ") ard (* 2 crd) ; Approach radius erd (* 3 crd) ; Exit radius aof (* 0.0375 crd) ; Approach offset eof (* 0.1236 crd) ; Exit offset ) ;;----------------------------------------------------------------------;; Tho that is pretty cool way to set a bunch of variables with lambda

Thank you For the suggestion. I believe the only solution to solve this is Lisp or similar . i need to change the text height without exploding the dynamic and sub blocks. the reason for this is that this beam block does not work alone . There are several other blocks that work alongside it . All attributed in a similar way . i need the ability to control the text height via the text style name and the only way to do this is via an intrusive script .

one work around might take some work, might work If you are happy with the text sizes being incremental se up your attributed dynamic block as you have now. Set these as a visibility status, lets say called "1-1" Add fields positioned as you like and suitably sized to be larger or smaller text, set their visibility status, lets say"2-1" or "1-2" - larger or smaller as you want. Each attribute will be linked to a field - change the attribute the field text also changes. When you insert the block and set a status then only the attribute or field should show which should be the size you want. I say should.. I haven't tried this

Coming back to this one: Annotative Text, I find that I have to create the text style and then add the extended data to convert it to annotative text Handy that this can have an if loop in it and be used to create either normal or annotative if you want to adjust it: (defun c:MakeAnnoFont ( FontName FontStyle / Height NewFontEnt exdata newent ) (setq Height 0) (setq NewFontEnt (entmakex (list '(0 . "STYLE") '(100 . "AcDbSymbolTableRecord") '(100 . "AcDbTextStyleTableRecord") (cons 2 FontName) '(70 . 0) (cons 40 Height) '(41 . 1.0) '(50 . 0.0) '(71 . 0) (cons 42 Height) (cons 3 FontStyle) ;; Font style to include suffix e.g. '.ttf' or '.shx' '(4 . "") ))) ; end entmakex, end list, end setq ;;Add xdata - annotative text (regapp "AcadAnnotative") (setq exdata '((-3 ("AcadAnnotative" (1000 . "AnnotativeData") (1002 . "{") (1070 . 1) (1070 . 1) (1002 . "}") ) ; new extended data— )) ) (setq newent (append (entget NewFontEnt) exdata)) ; Appends new data list to entity's list. (entmod newent) ; Modifies the entity with the new definition data. (princ) ) I don't use a lot of annotative dimensions to make a LISP worthwhile, but reading this week I think the method is the same, create the dimension and then add the xdata to it afterwards.

You have no idea how long I have been looking for a LISP that does this!!! I tried to hard code some of the values but I am messing it up somewhere (and I don't have enough knowledge of LISP to debut it...). Can someone please let me know how to change the code to put into it the following: (setq ard (* 2 crd)) ; Approach radius (setq erd (* 3 crd)) ; Exit radius (setq aof (* 0.0375 crd)) ; Approach offset (setq eof (* 0.1236 crd)) ; Exit offset Basically, I just want one prompt for the middle radius, the rest are calculated with the above formulas.

Calculating an axis using angle bisectors a) Attempt number 1 (it was my first impulse, but I came up with a better one later) Advantages: - Pure LISP: doesn't depend on Express Tools, - It's faster Disadvantages: - The result isn't as good as @GP_'s "c:CPL" - It only accepts LWPOLYLINES and ignores arcs Basically, the approach is to obtain angle bisectors on each polyline, extend them to the other reference polyline, and use their midpoints. The result is acceptably good, but not as accurate as c:CPL.

As I said at the beginning, there's a better approach, using angle bisectors, which I'll publish later.

If I get any time at home, I'll do some testing in AutoCAD 2000i.

Try mine...

There may be different versions at the Swamp as well. John Uhden has a few versions.

@symoin Can you please explain the logic of getting an elevation from "Profile-sample.dwg"? It is kind different from the picture which were you posted above. If I am not getting wrong, from picture below, the elevation need to looks like this (so, the equidistant need to be equal?): Best regards.

HI~there First of all, thank you to anyone willing to help me. I need a LISP routine. Command name: CCW (Column Cut Wall) The workflow is: first select the yellow layer (columns), then select the green layer (walls). The routine should trim all wall lines that are inside the closed polylines on the column layer, including cutting and removing any wall lines that overlap with the column boundaries. lisp request.dwg

I know of and have previously tried StripMtext V5.0c which didn't remove the height override. Some additional searching and the second version of v5.0d I found does remove the height override! Located here, message 54 - Solved: strip mtext formatting - Page 3 - Autodesk Community Previously the version from John Uhden removed my stacking formatting which I wanted to keep. Thanks for your help!

Here is the profile sample PROFILE-SAMPLE.dwg

It's true... sorry I'm curious to see if there are any differences.

Yes, I added (acet-load-expresstools) Answered by me. Gian's (as well as the other LISPs) still want to cut some corners short, etc. IMHO. @mhupp's actually does some of the corners better, though "off" in other places. I believe Civil 3D has something to do this, but it may not be much better. If I get more time I'm still going to work on improving mine.

Normally the final result is a polyline, maybe you don't have ExpressTools loaded, try: (or acet-flatn (load "FLATTENSUP.LSP"))

HI, I’m working on a CAD drawing that has several parallel polylines, and I’d like to space them out evenly by a fixed distance, but only from their start points. For example, all the lines begin from point No. 1, and I want to distribute only between line 1 and line 2, keeping the rest aligned. The goal is to spread them equally on the opposite side, similar to how the “Distribute” option works in TEXTALIGN, but for polylines instead of text. It would be great if the spacing value (for example, 0.2 ft or 0.5 ft) could be entered by the user. Does anyone know if there’s an existing LISP routine for this, or something close? Any tips or examples would be really helpful. line shifting.dwg
