  1. Hi! First of all, This is my first post here and I'm not an EXPERT in english, so I will try to explain as good as possible. I'm using Inventor 2012 and AutoCAD Mechanical 2012. In Inventor I have a piece in which it was applied the punching tool (Custom one) it works Perfectly, but when I export it to autoCAD it comes with too many points or vertex, I know if I draw it in autocad I wont have that problem, what that's why we use a Punch Tool, to simplify things and get things easier and always the same. Re-draw is out of the question, unless its the ONLY solution.. We use two CNC Plasma Machine, one of them uses the Software CamBAM and it can edit the vertex and simplifies it and jobs done, but it cant export the job to .dwg or .dxf.. and the second and new machine (the one i'm having trouble) uses FastCAM software, it has something similar to adjust the vertex but, the real problem is within the FastNEST.. Either way, the best solution is to fix the drawing in autocad. EDITPOL doesnt work, as it just joins it, I need to make less points.. I could Upload the file if needed. I'd Really Appreciate any help given. Thanks and Again sorry for my many typos.o:)
  2. Dear all, I'm a newcomer I already read the forums a few times and found answers all the time, but sadly its not that time. My problem is te following: I got a 61MB big drawing which i should modify. Sadly my computer isn't fast enough to handle that much information. I attached an example which shows why the file is this big. (Sadly i'm not able to upload this in dwg, because the example file which i made also takes 5MB of free space... ) There you can see that loops are made from much-much more lines than needed. If i could unite lines which has the same X or Y coordinates that would come out in a smaller file size and lesser CPU capacity. Do we have any command which does something like this? Do you have any other idea how to correct this kind of thing? Any help is appriciated. Thanks in advance! The picture about the problem:
  3. Hi All, I have a non-square polyline and I would like to either shrink or expand it by, for example, 1 mm in all directions. The scale command doesn't work because that keeps all of the ratios the same which I don't want to happen. I'm using AutoCAD 2013. Thanks in advance for any suggestions.
  4. I work as a boat designer and often require calculating total length of polyline & centre of gravity (both open & closed polylines). I have a snippet below to show the sample code I am currently using - this only works with a group of lines - it doesnt work with polylines. Currently everytime I have to calculate the CG, I have to copy the polyline over, explode it & select the lines to calculate the CG. The logic is as follows - assuming we have 3 segments on the polyline(A,B,C) : Centre of Gravity of Polyline = (Len of A multiplied by Centroid of A + Len of b multiplied by Centroid of B + Len of C multiplied by Centroid of C) divided by Total Length of polyline I am new to LISP & although have some background in other programming languages, find it is relatively difficult to write the code, the syntax being very different. I found a similar code ( TotalADD Total Addition by Andrea Andreetti & modified to come to the below code). It would be ideal if I can select a group of polylines (using select similar) and run the command to get a text table in autocad with CG & total length calculated for set of polylines on different layers. But I am not sure how this can be achieved. Would you be able to help or am I asking for too much ? any guidance will be much appreciated. (if (eq (vla-get-objectname n) "AcDbLine") (progn (setq itemlinelength (+ itemlinelength (vla-get-length n))) (setq StartPoint(vlax-safearray->list (vlax-variant-value (vla-get-startpoint n)))) (setq x1 (car Startpoint)) (setq y1 (cadr Startpoint)) (setq EndPoint(vlax-safearray->list (vlax-variant-value (vla-get-endpoint n)))) (setq x2 (car endpoint)) (setq y2 (cadr endpoint)) (setq xmid (* (+ x1 x2) 0.5)) (setq ymid (* (+ y1 y2) 0.5)) (setq xmom (* xmid (vla-get-length n))) (setq ymom (* ymid (vla-get-length n))) (setq itemxmoment (+ itemxmoment xmom)) (setq itemymoment (+ itemymoment ymom)) ) ) (setq totxcg (/ itemxmoment itemlinelength)) (setq totycg (/ itemymoment itemlinelength)) (setq tlength (rtos itemlength 2 ) (setq totxcg (rtos totxcg 2 ) (setq totycg (rtos totycg 2 ) (acet-ui-status (strcat "Length: " tlength "\n" "X CoG Pos: " totxcg "\n" "Y CoG Pos: " totycg "\n" )
  5. Hi to all, Please someone knows one lisp to get length of a PL (polyline) and write it above this PL in associative and dynamics form? As the Picture. If the length is changed the text follow these data. Thanks in advance.
  6. Hi everybody, this is my first post. I need a Lisp to generate a polyline from existing points. The polyline should be created from all the points at the edge of the cloud of points generated by a 3d scanner. The points are in 3 dimensions, but they could be flatted to zero. The polyline can be close or open: it does not matter. Any idea? Thank you folks in advance. dave:acad:
  7. Hey guys, I'm trying to get the four corners of a rectangle in modelspace set to variables and I'm having a hard time with it. I'm able to get the four corners into a list, but I'm having a hard time setting each coordinate to a variable. The issue I'm having at this point is that the second variable duplicates the coordinate values. The first variable Here's what I got so far... (defun c:test (/ ptlist x y) (setq ptlist (massoc 10 (entget(car(entsel))))) (defun c:massoc (key alist / x nlist) (foreach x alist (if (eq key (car x)) (setq nlist (cons (cdr x) nlist)) ) ) (reverse nlist) ) ;end (princ ptlist) (setq x (car ptlist)) (setq y (cadr ptlist)) (princ) (princ x) (Princ) (princ y) ) I got part of this code from here When I draw in a rectangle in modelspace and I use this code, this is what I'm getting. Command: TEST Select object: ((18.2488 -11.0958) (23.6419 -11.0958) (23.6419 -5.32136) (18.2488 -5.32136))(18.2488 -11.0958)(23.6419 -11.0958)(23.6419 -11.0958) So it builds the list and sets the first variable right, but it duplicates the second. Thanks in advance! e: I haven't added in error trapping yet, just trying to figure this out first.
  8. Does anyone know of a field expression or lisp routine that will allow me to display a count of the number of polylines on any specified layer? I would like the number displayed to be able to update as I add polylines to the layer, just as an area field expression would update on regen. Thanks very much
  9. Hi I am using AutoCAD 2014 'Architecture workspace' and I use the Properties palette a lot to change the attributes of linework to display linetypes/global thickness/scale etc. However, when I click on the model item (eg. polyline) the Properties palette doesn't change to inform me what the properties are of that item. Instead, it stays the same as the default properties type. Also, things like Global Width/Length/Area etc do not show in the Properties box - is there a way of loading or changing this as I believe I might have the wrong Palette loaded etc ?? Is there a way to load a new palette? Please help? Cheers Paul
  10. Evening All I work as a design assistant for a West End Set Designer who loves working in forced perspective & vanishing points. My question is how do I slice/trim a 3d polyline that runs through a solid. I basically want to cut the line once it touches the face of the solid. I would be also happy to add a node. Attached is a small example of the working file. Look forward to your responses Cheers James EXAMPLE.dwg
  11. Hello, I am working on a tunnel alignment. I have to draw multiple closed 3d polylines from AutoCAD Points (which form the tunnel sections from the excavation). I use the 3POLY command and then the option "PN. Is it possible to write a script (or a lisp routine) that repeats this process? For example, I wrote this script 3POLY 'PN 1-10,1 (1 row blank) 3POLY 'PN 11-20,11 It draws the first closed 3dpoly (from point numbers 1 to 10 and closes to 1) but it not continues to second 3poly. Thank you in advance
  12. I have been searching for a very long time and i hope you can help me this way cause i found nothing. The thing is, i have a polyline and set its thickness but i need something like 3DFACE which can cover those open areas on the bottom and top. Nothing ever worked, except for dividing it into million pieces and applying 3dface/loft for each, lol
  13. I need a lisp routine that can take a long polyline and delete all the arc segments, thus leaving multiple shorter polylines (all consisting only of straight segments). Can anyone help me with this please?
  14. Hello. I have a drawing with a few layers, and in two of them i would like to know if it is possible to move one vertice of a polyline (in layer AR_COLECTOR_GR_200), and automatically move vertices of the polylines (in layer AR_RAMAL_LIGACAO_PVC_125) snaped to the other polyline in layer AR_COLECTOR_GR_200. The same happens when i have to move objects in layer AR_CAMARA_VISITA_NORMAL and then, i have to manually move objects connected to them in layer AR_COLECTOR_GR_200. This happens because i have gps points and i have to move objects in layer AR_CAMARA_VISITA_NORMAL to those points, and then update the position of AR_COLECTOR_GR_200 and AR_RAMAL_LIGACAO_PVC_125. Check the attached file to better understand my problem. The doubt is to know if there is any method available to go from step 1 to step 4 without having to make those updates manually Thanks for any help TestFile.dwg
  15. Hello guys, well i have a homework for the exams and i have no time, so i need your help. The question is, how i can measure the exact length of an arc (or a polyline) ? See the pic.
  16. Hi guys For some reason I can't extrude this polyline. I'd drawn it as a bunch of splines at first, but then I found out that they weren't joined together. I traced over all the individual splines with one spline, and then deleted everything underneath. It still won't extrude. Can anyone tell me why? I tried a bunch of things--pedit, joining, etc. Nothing. When I click 'extrude,' the command thing says 'select objects to extrude or [MOde]:'. I clicked my spline and it highlighted, and then I hit enter. The message doesn't change. Any suggestions?
  17. Hi there all, I am new here so forgive me if my question is vague or likewise is a bit over the top. I have been sent a client's construction drawing for a care home where i need to design the sprinkler installation. The majority of the rooms have got the same head positions within them, but they have all got a slightly different angle as the building is shaped like a banana. Unfortunately its not a uniform radius that i can tell as the one side is larger than the other. So my question is this. Normally, on a square building, I drop in construction lines along the bedrooms so that i know my sprinkler heads are all the same distance off a wall, and I only need to line up one side. However, with this building being a curve, and the wall angle being slightly different on each room, how do I place an angled construction line or polyline to act as my set out line for my heads. Ive been looking at the drawing and various forums now for the past 2-3 hours and still haven't seen an answer that helps greatly. Thanks in advance, Richard
  18. Is there any way to find out the Maximum vertical distance between two polylines?
  19. Does any body have any idea how can we find out the Text and Polyline intersection location using Autolisp? It will be better if we can mark error circles on a perticular layer on the intersection. Thanks in advance
  20. Hi, Earlier today I was joining some polylines and during the command AutoCAD temporarily froze. After a short time it resumed and I completed the task. However, after this some other polylines which have a thickness applied took on a 'wire-framed' appearance (see attached image where one of these lines has been selected). Now, I've had this happen before, but always been able to easily fix it with a regen or re-launch of the file or AutoCAD itself, but now that is not working. I even rebooted my PC but this did not help. It seems this only affects the file I was working on, an older copy of the file displays the same lines as normal. So, has anyone encountered this and is there a 'fix'?
  21. Hi all, I have a small question here. Is it possible in autoCAD (or via lisp) that when I draw a polyline and when I reach the first point again (from where I have started), the command terminates and give me a closed polyline. And if I dont reach to the first point, it automatically closes to the first point. This is just me make sure I'm not keeping the loop open for hatching? Any help is appriciated.
  22. Hello everyone, in order to obtain a seabed profile for a school project, I need to get the Y coordinate of a polyline on several Kilometers with a fxed X step of 2m between each point. For the moment, the only manual solution I have found is to create a vertical line every 2m and to get the distance between the intersection of this line with my polyline and an horizontal line representing the mean sea level. Is there any way to automatize it because it is very long to do manually and I don't have enough time ? I did not succeed in doing this with dataExtraction. I also found on the internet a LISP file which extract the coordinates of points contained in the window. Nevertheless, I was told it is not possible to create automatically points on a curved polyline with a fixed x step. What I need at the end is an excel file of this type to use it in another software: X(m) Water Depth (m) 0 15.121 2 15.134 4 15.147 ... ... I precise I am a beginner in autocad, I have started today. Have you got any idea to solve this problem ? Thank you in advance
  23. Hi, As the thread title suggests, I want to create a segmented polyline with known angles / lengths, but I want to do this in 1 operation without having to copy/rotate/chamfer etc. I think I'm gonna kick myself when I receive an answer to this as it seems to be something I should know. I'm sure it has something to do with UCS, but I've not used it in quite some time, I am stumped and everything I have tried so far has failed.
  24. Dear Lisp Masters, I need help to do this: 1 - Insert a Multileader with a user defined block - OK, no problem. 2 - Pick to place block - OK, no problem. 3 - Pick to place arrow - OK, no problem. So far so good, then a lisp capable of: 4 - Pick to select a polyline. 5 - Collect some info from polyline such as width, lenght, layer, vertices coodinates (x,y,z) etc. 6 - Pick to select a Multileader 7 - Insert the collected info into the block attributes values. It's possible to do that? Greetings from Portugal!!!
  25. I made a very simple lisp to draw a line according to a requested slope ratio like 1:4, 1:10 ect it works fine for "normal" angles, but when it comes to ratio like 1:60 or 1:0.001 the result is inconsistent... I mean sometimes it will be displayed fine, or on the x axis (ie with no inclination at all) or will draw only a point with no length or will snap to another line (sitting very close) And all of that even if the values for the end point are correctly computed... Something else, if I draw a very long line like (1700 m) then it's always displayed correctly... If someone has an idea/ explanation I'll be very thankfull here is the code (defun C:slp( / refpt dirpt x_ratio seglen xref yref dirangle reqangle xend yend) (setq refpt (getpoint "\nPick a reference point")) (setq dirpt (getpoint "\nPick a direction point")) (setq x_ratio (getreal "\nSlope ratio 1:")) (setq seglen (distance refpt dirpt)) (setq xref (car refpt)) (setq yref (car (cdr refpt))) ;zref=0 (setq dirangle (angle refpt dirpt)) (setq reqangle (atan 1 x_ratio)) (princ (strcat "\ndirection angle: " (rtos dirangle) " requested angle: " (rtos reqangle))) (cond ( (and (> dirangle 0) (< dirangle (/ pi 2))) (setq xend (+ xref (* seglen (cos reqangle)))) (setq yend (+ yref (* seglen (sin reqangle)))) (setq endpt (list xend yend 0.00)) (command "pline" refpt endpt "") ) ( (and (> dirangle (/ pi 2)) (< dirangle pi)) (setq xend (- xref (* seglen (cos reqangle)))) (setq yend (+ yref (* seglen (sin reqangle)))) (setq endpt (list xend yend 0.00)) (command "pline" refpt endpt "") ) ( (and (> dirangle pi) (< dirangle (/ (* pi 3) 2))) (setq xend (- xref (* seglen (cos reqangle)))) (setq yend (- yref (* seglen (sin reqangle)))) (setq endpt (list xend yend 0.00)) (command "pline" refpt endpt "") ) ( (and (> dirangle (/ (* pi 3) 2)) (< (* pi 2))) (setq xend (+ xref (* seglen (cos reqangle)))) (setq yend (- yref (* seglen (sin reqangle)))) (setq endpt (list xend yend 0.00)) (command "pline" refpt endpt "") ) ) ) Thank you all
