  1. hi i am making a wiring to autcad blocks using polyline and then i make fillet to smooth the angle, what i need is after making all wiring i want to trim the wire that is pathing internally thanks in advance for any help the snapshot picture at
  2. HELLO AGAIN CADTutor! I have a problem of weather of not you can change the accuracy of the calculation of areas in AutoCAD 2011. In my line of work, we need to find the areas to exact precision, though it seems that my AutoCad is messing with the calculations and rounding up. E.G AREA - .017666 and turns it into .002 I calculate the Area thorught the usage of Polylines, and or the area command when i need to. Can anyone please help me find some insight on to this, mabye to change it to give me EXATE AREA!? Any and all help is greatly appreciated, those who are deemed awesome get a virtual cake, and the cake is NOT a lie....
  3. I need help to calculate area of multiple closed polyline shapes. In my drawing I could have hundreds of shapes as shown in the picture. I want to find total of the shaded area by adding the area of the outer shapes. Then subtracting the area of the Inner shapes. Maybe there is a better way to do it? Any help would be appreciated. Thanks.
  4. Hi, I'm a french user of AutoCad, so I hope my english will be great. I work in public work. For a new project, our client gives us : *___a large amount of plan representing *____________"pull box" (burried in the ground) *____________section of cables connected to the pull box. *___for each plan, we have an excel table which give us for each section *____________the start pull box *____________the finish pull box But we don't have the length of section in this table. We have a lot of plans and for each plan, there are lot of section. Pull box are block with attributes section are polyline. We are looking for a code who can extract the length of all section of a plan Is there someone here who can help me? a lisp code that is almost the same that i'm looking for ? something i can adapt ? Thank you in advance. If you have question, don't hesitate.
  5. I'm having issues in a particular drawing with moving a single polyline. I'm trying to move one polyline, but it instead moves all connecting polylines and some nearby polylines. My specific example: I have a layer for the existing house, a layer for a hedge, and a layer for a fence. The polyline for the hedge is currently touching the polyline for the house and the fence polyline is next to it (but not touching). When I click on the hedge and try to pull it away from the house (whether from the end grips or midpoint) it will also try to move the polyline of the house that it's touching and the polyline of the fence that is closest to the hedge. When I try to move it using the MOVE command, the same thing happens. I've tried shutting down CAD and turning it back on, opening it on another computer, flattening the entire drawing, and copying everything and pasting it into a new file. Nothing has worked so far. Any ideas on how to fix this?
  6. I'm making a polyline arc and would like the arc to go the other way. What button do I press to make that happen? I stumbled upon it one day, but have forgotten the button. Anyone know?
  7. Could someone help point me in the right direction here? I want to filter a selection of polylines (contour lines) by their Z value (ie filter to get only 10' or 5' or 2' contours). I assume I need to test the Z value to see if it is a muliple of 10, 5 or 2, etc... Any hints on hhow to get this sarted? Thanks
  8. Morning all, I am very very new to autocad and trying to solve an issue I have at work regarding line types not showing up correctly. I have several .dwg files which I attach using XREF so that I can ensure I have the latest versions combined. The problem is that the line types do not show up correctly. After looking up on google I have found that this is a problem due to it being a 3d model rather than it being flat. I managed to half solve the issue by inserting each drawing into one, then exploding the whole image. Then changing the scale in the bottom right to around 1:200 to make the line types visible. My problem is this ends up being alot of work as the separate drawings can be updated daily. Is it possible to have all the drawings Xref'd in and to be able to have the scale changed to be able to read the line types? I tried to save the XREF setup as a template, then just bind all the drawings into one, explode and change the scale. But for some reason this doesnt work for me. I end up with just solid lines, rather than line types. I don't think it helps that the drawings are made up of several lines, all of different length. (This I have been told is why the scales do not appear correctly) I have been shown one method to work around this, which is to open the Xref drawings, explode them, then take each section of line and manually change each scale to the biggest that shows up. A very painful process when I might need to do it everyday!!! Any help would be appreciated.
  9. I need to know how to get the start and end points of a polyline. I'm a rookie at this and just learned how to pull out the start and endpoints of a line and when I went to do it to a polyline I was completely lost. Another question: I use a comand that takes a line and turns it into a perforated line with each segment being a separate poly line. It creates them all in order down the line. Immediately following this command, would there be a way to call the first poly line created to extract its data, without manually selecting it?
  10. Hi All I have been searching for a way of exporting multiple polyline or spline coordinates to txt file and all I can find is ones that write out as a single continuous list of coordinates with nothing denoting which one is which. I really need it to be able to export each polyline as a group, and I would also love for it to be able to include the number of points and name of the layer eg: polyline 'number of points' 'layername' 0.0 0.0 0.0 1.0 1.0 0.0 2.0 2.0 0.0 polyline 'number of points' 'layername' 0.0 0.0 0.0 1.0 4.0 0.0 2.0 8.0 0.0 and so on..... Any help with this would be much appreciated
  11. Hi, im working on a project for university and it involves using .shp files, which i've imported fine, however the problem is that when i draw a line or polyline then save the file, close the program, reopen the file, the polyline appears for a split second while opening but then it disappears once the shape file loads. the polyline is on an active layer and i cant find it even when i untick the shape file in the task pane box so that there is nothing else in the drawing window. Any help would be greatly appreciated!
  12. Hi, Is there any way at all to draw a new polyline - from the endpoint of another polyline, and have it automatically join as one polyline from the existing section?? I know this can be done via PEDIT, but its so laborious and soo many clicks, and I have alot of segmented Polylines that I need to consolidate when I draft. Any assistance would be greatly appreciated! Thanks! Matt
  13. I have a great request. I need to scale some polyline contours from ground to grid coordinates. Using the scale comand this works, but the Z value is scaled as well. The thing is, I want to scale the X and Y only, not the Z. So far the only way to do this is to create a block, scale it, then explode. This takes a lot of time that to me seems unnecessary. So this is what I was thinking for a lisp routine that can do what I need. Select a polyline (contours) Scale the polyine to some factor. Reset the Z value to the orginal value before scaling. I hope this makes sense. Haha. Anyone willing to tackle this?
  14. howdy, I found this code: (defun c:ppav () (vl-load-com) (setq *model-space* (vla-get-modelspace (vla-get-activedocument (vlax-get-acad-object)))) (setq obj (vlax-ename->vla-object (car (entsel)))) (setq c (vlax-get obj "Coordinates") i 0) (repeat (/ (length c) 2) (setq x (nth i c) y (nth (1+ i) c)) (vla-addpoint *model-space* (vlax-3d-point (list x y 0.0))) (setq i (+ i 2)) (setq temp (osnap (list x y) "mid")) ; I added this (command "point" temp) ; and this ) (princ) ) and added the two lines to try and get points set on the midpoints of the pline segments....but it does not work as intended. Some midpoints are set on the wrong segment and 1 extra point is being set. Can Anyone Help? thanks Ray

    Polylines have only one handle

    I am working in LT 2008 and the program spontaneously started making polylines with just one handle. I am picking the button on the tool panel, not doing anything different. I am working in a complicated floor plan from a client working out square footage of various areas. When I draw a polyline in an open space I get handles at each corner, but if I trace over existing lines on locked layers there is only one handle at the start point. I have been working on this drawing for several days and the issue just started today. Any solutions would be appreciated. Please note, I am a user of AutoCAD (15 years), not a programer so talk down to me, I won't be offended.
  16. Hello all, I want to put a text about the polyline. Now I do the steps listed below. 1. polyline with Len2Fld.lsp read. 2. edit text for the street, material and diameter. 3. text-align with DTCurveV2 9.lsp. (Thank you very much Mr. Lee McDonnell.) It is a procedure if a large enough clusters with 50,000 inhabitants. The above-mentioned wish to edit in a single pass. -polyline-read length, choose the material and diameter (from a list) and finally to have an open field where you enter the street name or other (can be 2 to 3 fields to fill). Attach to a water network example I apologize for my English. I'm use Acad2008. Best Regards. Sample Water Network 3.dwg
  17. I've heard that you can reduce file size using polyline instead of line while drawing (or vice versa... don't remember) Could you advice please, is it true and what exactly should be used. I think, why we would need the line tool at all if polyline more convenient... unless I am missing something... ?
  18. Hello, I am working in AutoCAD 2010 and am looking for a LISP routine to report the area of counterclockwise polyline loops as a positive value and clockwise polyline loops as a negative value(as with the right hand rule). For example, if I have a poly line that crosses over itself multiple times creating several loops of different areas with the majority of the area coming from clockwise loops I would want the total area reported as a negative value instead of the absolute value that is reported in the propertes of the line. Does anybody know of anything that fits the bill? Thanks
  19. Hi. I use wipeouts a lot. Is there any way to automatically create an outline around a block that can be converted to a wipeout? Some of our blocks are complex, and it takes a fair amount of time to create. Thanks in advance!
  20. Hi everybody. I am new to lisp, so I need your help. I have a diagram with different lines. I need to select each line separately and change a color and a line weight of it. I have one problem right now. here is the example of my selection set line (setq ssLine (ssget "X"(list (cons 0 "LWpolyline")(cons 8 "0")(cons 62 253)))) I want to keep everything the same except the last CONS (cons 62 253). I want it to take a value of a color from a object that I will select in my drawing. First, I need some command or variable to prompt me to select a line. After that, I need my selection set to change the last cons from color 222 to a color of the selected object. Thank you, AB
  21. I started developing a lisp that will check all the polylines in a drawing for either the x or the y coordinate to be equal and change the color of each polyline that does not meet the criteria to red from "bylayer". I am having trouble with looping through each object sequentially and also the loop comparison of each vertex within the current object. Where I am trying to get to again is to check that all polylines within an architectural type of drawing are square and to alert which ones are not. I'm not a lisp expert so bear with me. If you want to correct my syntax great, or tutor me on what I'm doing so dreadfully wrong--even better. Thanks, Randy (first post) The code so far: (defun C:perp() (defun A1() (setq eFilter(list (cons 0 "polyline"))); entity names into a list (ssget "X" eFilter) ); ends defun A1 (defun B1() (setq eLen(length eList)); gets length of list ); ends defun b1 (defun D1() (setq Lwn 0); variable initial definition (setq e 0); ditto (repeat eLen ; repeat for length of entity list (setq e1(car (nth n e))) (if (= e1 10) (progn (terpri) (princ (cdr(nth n e))) ); closes progn ); closes if (setq Lwn (+ 1 Lwn)) (setq a (cdr (nth n e))) ); closes repeat ); closes D1 (defun Esub() (trace Esub) (setq coordLen(length e1)) ); closes Esub (repeat coordLen; repeat for length of coordinate list (defun G1() ;parse coordinates into xa ya xb yb (setq a (cdr (nth coordLen e))) (setq b (cdr (nth (+ coordLen 1) (+ e 1)))) ) ; ends G1 ;---------------BEGIN SUBROUTINE H1---------------------- (defun H1() (setq xa(car a)) (setq ya(cadr a)) (setq xb(car b)) (setq yb(cadr b)) ); closes H1 (defun H2() (= 0 (- xa xb)) (= 0 (- ya yb)) (T (Command "chprop" "p" "" "c" "red" "")) ); closes h2 ); closes repeat )
  22. Does anyone have a lisp routine that can create a polyline from a given area & one given x or y distance? We have a list of room areas that we must have the exact SF & fit several of these rooms into an existing floor plan. It is very tedious to change a vertex to get the SF.
  23. Hi, I need to transfer some plumbing (or piping) from Autocad to a another program for specialist analysis. This analysis requires that I have the piping as 1m length pieces. I have found lisp code to measure the line and place a marker (block) every 1 metre, and also have a program to extract the block co-ordinates to a text file (which then allows me to reload the line into the the third party app). However this process cuts all the corners, so my re-constituted line is not exactly what i started with. I need a lisp code that measures the polyline, but also places the block marker at the vertex's of the polyline. As a secondary item is it possible to use text as the block, and modify the text so that it extends 1,2,3,... alond the line, - this would assist me ensure that the line is re-constituted correctly in the third party app - particularly when I want to do several lines at the same time. I've some experience with Autolisp way back at R10, and again R12, but not touched it much in the last 10 years. So I think I could modify code provided, to suit R2006, if you prefer to answer in code only tested on R2010 etc.. Cheers!
  24. Hi, i'm still a beginner in lisp and need some help. I want to use some algorithms to simplify a 2D polyline but I don't know how to store the coordinates of each vertex in a different variable. thank you in advance
  25. I have a drawing that, at some point, was changed to have a default polyline global thickness of 15 regardless of any plot styles. I can change each pline manually to be 0, but new ones are always 15. How do I go about changing the default so I don't have to deal with these silly thick lines?
