  1. Hi all, I am trying to write a LISP routine to list all the vertices of selected MPolygon. I have one MPolygon and 5 polylines. The sample drawing is attached. Basically, I want the program to create vertices on the MPolygon where the polylines touch the MPolygon (meaning there is no gap between them) and store the coordinates of all the vertices into a variable. Thank you Best wishes, Jes G sample_MPoly.dwg
  2. Hi all, I found this LISP routine by Tony Hotchkiss from here. If I understood this correct, it works with LWPolyline, Polyline and Point. For some reason it does not work will all polylines on my drawing.

Or maybe my drawing can be modified using another LISP routine. In addition, I want the program to output two files. The first file would be the XY coordinates of all points of the polylines with number (kind of identification). For example, The second file would include the points and distances between them. For example, Thank you Best wishes, Jes G Sample.dwg
  3. Hello there, Merry Christmas! I am new in LISP and I don't know where to start from. For clarity, please refer to the snapshot provided. I am not quite familiar with AutoCAD terminology though, but I'll try to explain my problem clear. Basically, we have polylines and points having their coordinates (these small blue rectangulars). What we need to do is: Find the closest on the polyline from the "blue rectangular" Create the vertex on THAT point Export to Excel files the following parameters: number, Coordinates of each vertex, distances between them, '1' if the line contains newly-created vertex The output files are expected to look like: 1. XY_Coords.xls: Node X Y 1 359.898 163.788 2 358.514 164.124 3 358.423 164.131 4 358.354 164.119 5 358.26 164.07 6 358.198 164.005 7 358.153 163.91 8 355.136 152.963 9 354.962 152.691 2.

  4. Hello, there, I am trying to find a LISP routine which will find the closest point on a polyline from a selected block reference. This routine finds the closest distance between two objects by selecting both objects, but it does not seem to work with block reference. After it finds the closest point, how to create a new vertex on that point? Thank you in advance Best wishes, Jes G
  5. Hello everyone. This is my first time posting but i have enjoyed a lot of your great work. I use a lot a field about object/polyline/length - decimal 0 (copy it to different polylines and than get their lenghth) and i am tired of changing object from dialogbox. Is there an easy way (lisp or other) to change the object directly and get its length:):)
  6. Hello guys, Someone knows if's possible I fill up one area, as the picture, with one polyline oriented (or as a guided line), informing the lisp code the initial point, the radius of return line, and the space limits (as the limits line), horizontal or vertical to guide the lines until the whole area it's completely filled up?... Thanks in advance...
  7. Hello, I'm using Lee Mac cad lisp program "PolyInfo V 1.3." for exporting polylines vertex coordinates. But for full work joy I need some modifications. URL for program: http://www.lee-mac.com/polyinfo.html URL for code: http://www.lee-mac.com/lisp/html/PolyInfoV1-3.html As you saw the program exports a lot of information about the polyline. So i want to modify the code that will export just polyline start vertex points x and y coords in two columns ( my cad version information exports to txt file ). The result should look like this: ________________________________ Polyline starts points x 649542.45 649542.35 649542.28 Polyline starts points y 495232.54 495232.23 495232.41 ________________________________ Can someone help to figure out which part of code I must to modify to get the result i want? Please.
  8. (Here is a link to the original post I am referencing) Hi Guys, I found this awesome lisp by Renderman/Black Box and I have run it a few times and it worked great those times. Then I tried to run it to convert maybe 20 wipeouts at once and a bunch of them disappeared. I would really like to be able to use this one time once I finish drawing all the wipeouts and not after everyone, but I also don't want to risk some failing to convert and having to redraw a bunch of them.

  9. I am hoping this will be a simple fix, but searching for the answer has turned up nothing. If I offset a self-intersecting polyline, it trims the offset anywhere that it crosses the original polyline. I am looking for a way for the offset to continue through self intersections untrimmed. My hope is that the self-trimming is a "feature", and that there is a way to turn it off, perhaps through a system variable or something. If not, the only way I can think to fix it is to write my own custom offset which doesn't sound very efficient. ps. Although I'm posting this in the general autocad area, I'm open to solutions that require autolisp. The reason I'm looking for this answer is to be used in an automated routine once I get past this hurdle. ***edit*** I found this thread , but it doesn't give a solution (aside from "use an ancient version on AutoCAD").
  10. Dear folks, There is an idea to get things easier in my workflow but I need check if it is possible or not. There are over 100 closed polyline objects on the model and each has a unique ID written in its Hyperlink value (like X_D_YYYY) And each of these polylines has a block placed in the enclosing area with an attribute. My aim is to get the Hyperlink from enclosing polyline and populate the block attribute with that value. You may find an example as DWG at the attachment. Regards. get-Enclosing-polyline-data.dwg

    Recognize multi-object shape

    Hi, I converted a pdf file into dwg. In this new file a point has become a group of 2D polyline and not a sigle entity. This conversion is necessary because I have to work in autocad. My problem is that I have to search in this dwg all of this "points" and write a text next to. Is possible to write a VBA program for autocad able to do this? If the point was a single point, it wouldn't be a problem, but in this case...I dont' know!
  12. Hi, Can anyone help me to write a lisp function to sort the points (assume the intersection points) on a polyline? With my code, I have a polyline object and a set of intersection points on it. I need to calculate the cumulative distance between those points and vertex points consecutively. Thanks,
  13. So I'm having an issue joining some polylines I have in order to make a dimer shape (two circles meeting at one point, with two lines connecting them). I started by making the circles, followed by two lines extending from circle to circle. I then trimmed the lines to get the attached geometry. However, I cannot join the shape, and was wondering how this could be done. Thanks! Dimer_Help.dwg
  14. While running in Line command I'm able to snap along the way, snap my running line to itself at each sub prompt: "Specify next point or..." When I try this with the Polyline command, while running polyline at each sub prompt: "Specify next point or..." no snap can be acknowledged. My Polyline won't snap to itself while running toward successive points. All Object Snaps are checked in it's dialog box. Alignment Point Acquisition is set to Automatic. Is there another setting or a system variable that needs to be toggled, maybe something related specifically to Polylines?
  15. Hello everyone, I work with a glazing company and am trying to write an AutoLISP command that will automate a large part of our job by dimensioning glass panels with holes and cutout in the format that our supplier prefers. I will attach a photo here to show what I have done so far. The rectangle on the left shows what I would like the dimensions to look like. The rectangle on the right shows what my LISP routine currently does. I am having trouble writing the logic to dimension it in the way that I want. Rules it should follow are: 1) dimensions strings should be made to the corner nearest to the hole 2) if two holes are in-line, the dimension should pass through the closer hole 3) if two dimensions go to the same corner, they should stack at 3" intervals (TYP. offset set for DIMBASELINE) 4) Dimension strings should always be 3" behind the larger dimension above them (See the 5" measure at the top left) However, these rules only hold true for the "rectangle" shape option. In the final version of the routine, I am looking to have an easily expandable list of rules that I can modify and tweak per-shape. I have attached a test drawing and the current version of my LISP routine below. The code for dimensioning rules on the rectangle is found on lines 436-494. Any help figuring this out would be much appreciated. Thank you! Drawing File: autodimtest.dwg Current LISP: autoDim.lsp
  16. 1st Post, woot woot. I searched through many of the existing forums but couldn't find one that addressed this issue... I work a lot with polylines, to create design contours. I usually have a contour at the bottom or top of a hill, then I use the 'offset' command to offset the line to conform to a 3:1 slope as far as I need, to tie into the existing topo. My problem is, after offsetting all these plines, they are all at the same elevation as the original line. Is there a faster way to change the elevation than clicking on a line, entering the elevation in the properties window, clicking on a new line, wash-rinse-repeat? This is very tedious, especially with 20+ offset lines each time. Or is there a way to offset with increasing/decreasing elevations each time? Thanks
  17. I'm still learning Lisps and am in the need of a function. I'm not going to say what i need it for, i want to try and write the lisp from the input of this forum. I need to know how to store the polyline width of a user selected polyline. for example, if i select a polyline and i run my lisp, or vice versa, the lisp will store the global width of the selected polyline into memory. (setq PW (ssget "polyline width") After i get this info, i will post my lisp and what it does. After you guys can share how you would have done it instead. and it will probably be better then my way. thanks ahead of time.
  18. i am new to all of this. would love to be able to remove all or most vertex's for any and all of my artwork. as for now i need to remove them from a circle. i do not know what the codes are for or how to use them. any help, would help.. i hopesecond sign Y.dxf second sign W.dxf
  19. I have a number of large files that have multiple layers with many simple objects. I wish to have a LISP program that searches the file and for certain layers, it looks for line and arcs that have the same start or end points I.E. a line has one end point that matches an arc or another line start point. Once it has found these, it converts the lines or arc into polylines and joins them together. I have a number of squares or rectangles that are constructed from simple lines and I want to end up with a closed polyline that is the same size as the original rectangle. This could also be an odd shape comprised of arcs and lines that is either open of a closed shape. I wont to convert these to polylines also (either open or closed depending on if the lines are enclosed or open). Can anyone suggest how to write this. I have very little experience of LISP.
  20. Hello to all, I have a challenge to place text markers along a polyline. As this polyline represents the trace of an linear object (in my case cable line) I would like to have at every 250m the length from the start of the line represented as "X +YYY", where X is the kilometer and YYY are the meters. Also it would be good to have the length from the start at every vertex. Can anyone help me with this, as I have no knowledge from lisp programing. Regards and thanks in advance!
  21. Hi all I'm working on some information that I have imported into LT 2017 from 12D survey software. Basically I have a road string (polyline made up of arcs) and I'm tidying it up. All I have done to this string is break it and change the layer it is on. When I go into Paper space and look at my plan layout, the broken polyline displays as though it is a full circle. In Model space it looks how it ought. I have double-clicked in the viewport and selected the circle and changed the colour for easy identification. Then, when I go back to Model space, I have a red curved polyline. No circle. I have also tried copying the polyline as a block and pasting it into paper space. It displays as it ought to. If I paste it back into Model Space, it retains its characteristics - i.e. curve in model space, circle in paper space. If I explode the polyline into its component arcs and join them together again, it begins to behave properly. This never used to happen in prior versions of CAD, and my co-worker has had a similar problem. She says it's not a consistent fault - sometimes the display behaves and sometimes it doesn't. I have run audits and purges and all sorts of fun things and have achieved nothing. It prints correctly, but the preview shows it as a circle also. Any ideas, or similar issues?
  22. Hi all, I thought there might be an intuitive/simple way to do this. I've tried the lisp routine SSX, BUT when you run the routine you can't "keep" the selection to use the PEDIT command. Is there something I'm missing here?
  23. Hello. I'm looking for a way to draw a polyline, where i enter the points with mouse clicking and when i click the final point and enter button, it writes in text the total lenght of polyline. I know that i can go to the properties and see the total lenght of the polyline and then i can use mtext to write that value near my polyline, but because i have to do that more than 1000s times, i was wondering if there is a faster way or a lisp routine. All ideas are welcome. P.S. I'm using Autocad 2009 and i'm beginner/medium user. Thank you
  24. Hi all, I am using AutoCad 2015, the problem I have is that when I select a polyline, do select similar and change the global width to 0.15 (for example) then when I save the drawing and re-open it, when I select the polyline and select similar, it says the global width is varies. I know this sounds like a rather minor problem but at work, everything gets checked and these kind of small errors do have a rather large effect on our performance rating. The strange thing about this is that it only happens for some drawings and not all drawings. Unfortunately that is all the information I really have on the problem so I hope that is enough. Thank you for your time, Josh
  25. I met a very "strange" behavior of VBA with Fillet Command send via ThisDrawing.SendCommand function. I have the function Fillet_2Line (line1, line2, r), which will apply the Fillet command to line1, line2 with Radius=R Sub fillet_2line(line1 As Variant, line2 As Variant, radius As Double) Dim text As String text = "f" & vbCr & "r" & vbCr & radius & vbCr & "(handent " & Chr(34) & line1.Handle & Chr(34) & ")" & vbCr & "(handent " & Chr(34) & line2.Handle & Chr(34) & ")" & vbCr ThisDrawing.SendCommand (text) End Sub As you can see, the function is very simple, call Fillet command from Autocad then select two lines by their handle. Use can reproduce the function without VBA by call Fillet command and select two POLILINES by their HANDLE. However, it works on LINE, but NOT POLYLINE. If I select two polylines by left click on them, it works. But if I select two polylines by their HANDLE, it does not work! Fillet 2 Line - Selected by left click - Works Fillet 2 Line - Selected by handle - Works Fillet 2 PLine - Selected left click - Works Fillet 2 PLine - Selected by handle - Does not work
