Recently I coded for just the same issue for PlPath that will draw paths from both sides (top+bottom)... Then you just have to remove sufficient one and leave the one that is OK... Here is the link : https://www.cadtutor.net/forum/topic/84000-create-a-new-polyline-from-two-on-a-path-of-a-polyline/?do=findComment&comment=637865

I've got something similar that trims a polyline between points, will find it out next week

greatttttt !!! and all the options will be used ? ; Brightness = 50 ; ClippingEnabled = -1 ; Contrast = 50 etc like (setq pt (vlax-get obj 'Origin)) ??? 'Brightness 'ClippingEnabled 'Contrast ???? i am going to try before your reponse sorry my bad english !! xDDD

Using VL lisp you can get properties. (setq obj (vlax-ename->vla-object (car (entsel "\nSelect a object ")))) (setq pt (vlax-get obj 'Origin)) DumpIt.LSP

THANKSSSSSSSSSSSSSSSSSSS !!!!! Absolutely GREAT!!!! You deserve heaven my friend!! Total perfection, just what I needed!!

Whipped this up real quick. but it has two problems, well I guess 3 but could be fixed easily enough. but its the weekend. depending on if the polyline is clockwise or counter clockwise direction the start and end points could be reversed. if the polyline has arcs would need to add a bulge function if the polyline vertex 0 is inbetween points picked will draw the inverse (not the green but the purple section) entsel could be a problem to in that you can select anything. ;;----------------------------------------------------------------------------;; ;; Draw Poly Segments between points picked on an existing polyline (defun C:PS (/ pline pt1 pt2 spt ept cords ptlist i s end) (vl-load-com) (if (setq pline (car (entsel "\nPick Polyline:")) ;get entity name of polyline pt1 (getpoint "\nSelect start point: ") ;get point on polyline works best with nearest pt2 (getpoint "\nSelect end point: ") ;same as above ) (progn (setq cords (mapcar 'cdr (vl-remove-if-not '(lambda (x) (= (car x) 10)) (entget pline)))) ;Extracts the coordinates of the vertices of the selected polyline into a list (setq spt (1+ (fix (vlax-curve-getParamAtPoint Pline (vlax-curve-getClosestPointTo Pline pt1))))) ;finds the closet vertex number to pt1 (setq ept (1+ (fix (vlax-curve-getParamAtPoint pline (vlax-curve-getClosestPointTo Pline pt2))))) ;same for pt2 (if (< spt ept) ;checks to see witch is bigger # (setq s spt end ept spt pt1 ept pt2) ;if spt is smaller then ept sets Everything they way it would work (setq s ept end spt spt pt2 ept pt1) ;if spt is larger then ept revises the order so its still draw correctly ) (setq ptlist (cons spt ptlist)) ;adds spt to a list (setq i s) ;sets i to the lower value of spt or ept (while (< i end) ;loops until i isn't less then end (setq ptlist (cons (nth i cords) ptlist)) ;keeps adding poitns to the list until while loops ends (setq i (1+ i)) ;used to step to the next point ) (setq ptlist (cons ept ptlist)) ;adds the last point to the list (setq ptlist (reverse ptlist)) ;list is in revirse order so reverse it (entmake ;make a polyline with new ptlist (append (list '(0 .

Hello, I'm going to explain myself. I am attaching an image for easy reference. The idea may be the one I give or something similar. What I think is, touch 2 or 3 points as seen at the top of the image I attached, and that the routine will be able to create a new poly, but only from that yellow section, as shown in the part of below the attached image. Thanks in advance for the help !!

Hello Bro, thanks for responding, I have no idea how to see that image data. I'm a real newbie. I also don't know where the dumpit.lsp file is located. Do you think you could explain it to me please? Thank you !!

Another lots of stuff inside if you know how to look, use dumpit.lsp ; IOdaRasterImage 8c6f5960 : TeighaX Interface for an additional Raster Image funtionality ; ; Property values : ; ; ; Height (RO) = 126.0 ; ImageHeight = 963.549313507815 ; ImageWidth = 3273.00877921702 ; Origin = (893.310512581778 -1166.27484437749 0.0) ; ScaleFactor = 36125.4520397692 ; Width (RO) = 428.0

Ignore multiple dwg's for moment. As you say only have title block once then its easy. (setq ss (ssget "X" '((0 . "INSERT")(cons 2 "EPCB000")))) You now have a selection set containing the block. (setq obj (vlax-ename->vla-object (ssname ss 0))) (setq atts (vlax-invoke obj 'Getattributes)) The variable atts holds all the attributes. You can then say change the value in each attribute, as you want to change many it makes it easy. You can just loop trough the attributes and change the "TEXTSTRING" the value of the attribute, you can also check for a particular attribute and say change G11 to G12. Ok next question how do you propose to supply the new values ? One way is to make a list of the new values say keep the code in a lisp file and just change the 1 line with the new answers, or keep the values in a text file change it and then run on multiple dwg's if required. This is the type of question linked to excel which can read say a row of details. The excel containing multiple dwg names.

The problem is that your hatches have their color property overidden to 255, which means they will print white. If you change your hatch color to bylayer or some other color, they should print fine.

I've been working on a project where I have used various hatch patterns to indicate sidewalks, bicycle paths and water. It shows up in my AutoCAD as shown on the screenshot, but the patterns are not appearing in either the print previews or the pdf's. Only one hatch pattern ends up showing up in the PDF, the diagonal lines underneath the street. I've tried changing "HPmaxlines" to 1000000, tried various plotters of AutoCAD and Adobe, reset AutoCAD settings. Nothing seems to work and I cannot understand why, as it shows up right there when I'm working on the file. Could anybody please take a look at the attached files and perhaps notice anything I've been missing? It would be much appreciated. The used Hatch patterns are ANSI31 scale 1 in gray (working) ANSI31 scale 1 in white (Not working), AR-HBONE scale 0.01 white (Not working), NET3 scale 1 in white (Not working) and a custom downloaded one which I applied in a second version. The issues were already there before I used the downloaded hatch pattern. Doorsnede Laan op Zuid Eindopdracht poging 1.pdf Doorsnede Laan op Zuid Eindopdracht 2 v1.dwg

Friend, almost a year later, I noticed that you had responded to me, how sorry I feel for you, I simply abandoned the idea that the XREF thing could be done. I apologize because I had not seen it. These days I will be reviewing the code. And I reiterate my APOLOGIES, please!! I forgot to mark FOLLOW TOPIC!! I am very stupid!!

Brooooo, you got it right!!!! That is the solution !! Is there a way to send you a small donation? I'm not wealthy, but I want to acknowledge your help!! You are great bro!!!

PlPath-t+b.lsp (top + bottom) is part of PLINETOOLS archive, so I am posting link where routine is posted publicly in code tag... Link : HTH. Regards; M.R.

One option would be to use a 3-point arc along with a dashed linetype.

No weld tool, I just extrude a triangle or sometimes Chamfer or Filet to smooth the connection.

I have my block EPCB000, which is my title block. I want to change all the text inside this block to new text. The drawing is a copy of an electric cabinet, but it needs new text details as it's for a new customer. Inside my block EPCB000, there are a few attributes: D12, D13, GODK_DAT, and so on. I want to update the value of those tags in bulk, and apply a few rules, such as using today's date. For example, if D12 holds the value "G11 This is a drawing", I want to update it to G12, and so on. However, I can't figure out how to read and write to those values.

Hello, I’m working on this project. I’m so glad I found this thread because I was having some trouble getting started. So far I’m almost done and I think it’s going well. I’m a little stuck on making the dimensions, I can’t seem to be able to make the arched and dash lines for the dimensions. If I could get some help I know this is old but if anyone could help I would appreciate it.
