AutoCAD Visual LISP / AutoLISP :: Selecting Multiple Objects To Export Their Coordinates And ID
May 24, 2013
I am just starting learning lisp, And I am looking for a fast way to select multiple objects (usually circle) and export their coordinates and ID into a excel sheet through lisp programming.
As you might see in the attached drawing, the red circles are objects wanted. I have been trying to export their coordinates as well as their IDs in grids, e.g D28, Easting: Northing: . I still haven't found a good way to export ID for each circle.
As my code doesn't work, I wonder what's the most effective way to detect errors in lisp
I have this code that I wrote years ago that I want to update to select two types of civil3d objects and show them selected with grips on the screen. This function works fine
but if I add the extra object like this which I assume is the wrong syntax i only get the second type of objects. Need correct syntax I should be using for selecting more than one object in an ssget statement.
I am looking for a method to export all the GPS coordinates which have been assigned to each point along with the properties of that point to an excel csv. In our drawings, there are multiple columns and each column has four points and each point has X,Y,Z coordinates. I want to export all this information to an excel sheet.
I am trying to select multiple objects and change them. However, the following code lets me only change one at a time. Even when I select a window around obejcts, it only changes a single item.
start of Same_Cannoscale.lsp(defun C:SCS ( / anno-v ent dict cansc entsc sc-list test oce) (setq anno-v (getvar "ANNOALLVISIBLE")) (setvar "ANNOALLVISIBLE" 1) (if (= (getvar "CVPORT") 1) (princ " In Paperspace. ") (if (setq ent (ssget ":S:L")) [Code] ........
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 e.g. :
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.....
I want to get the minimum and maximum x, y coordinate values of selected lines. In other words, i want to find the top, bottom, left and right edges of a set of lines.
I have created a circle from 3topo points. Im having difficulty getting accurate elevation (z) of the center of circle (pile representation) via cad polyline listing. im getting same "z" all through out which in fact is not.
I need to draw a table with point number, easting, northing, elevation for a lot of points and need a lisp to read the xl spreadsheet and draw the table.
I'm writing function which will facilitate user to offset dimension. After enter command, he select dimension and select point near one of dimension's arrowheads. Then I'm calculating new XLinePoint1 or XLinePoint2 and replacing original.
I have everything done. I thought ... The problem is when user firstly create AlignedDimension and after that he create RotatedDimension by using continous function. After that XLinePoint1 and XLinePoint2 are not parallel to the DimLinePoint (look at image).
How can I get coordinates of points selected in red rectangles?
I know that one is specified as "dimension line defining point" but what about second? How can I get its coordinates? Or maybe there is other way to get this point?
I recently wrote a lisp routine that was supposed to get the 4 coordinates of a rectangle (LWPolyline). It worked fine in *MY* tests. But when someone else ran it, the routine operated as though the order of the points had been rearranged.
How can I get the points AND the order in which they belong?
Here's a sketch to show you what I mean. As part of my troubleshooting, I had a lisp routine draw a new pline using the points gathered by my first routine. The result of that on the left. On the right is the result of that when someone else runs the two routines.
I am having nearly 1000 drawings where I need to change the title block in a new format.
I am stuck up in moving all the entities in cordinates 15,280 (upper point) and 205,55 (lower Point) to 275,294 (upper point and correspoing lower point.
i have found the following lisp in a previous thread: (shows XY coordinates of the selected blocks)
(defun C:MyFunc (/ ss Index Ename Lst) (while (or (not ss) (= 0 (sslength ss))) (setq ss (ssget '((0 . "INSERT"))))) (if ss
[Code]....
I want this information to be added to the blocks as hidden attributes so that i can extract them by attout. The work to be done is : attout to excel, autofill an attribute (numbering) then attin.
but my problem is that i cant think of a way to number those blocks IN ORDER (ie top to bottom or left to right) unless by sorting them in excel first by their x or y coordinates
I don't have a clue where the '-450567.0' is coming from.
I'm in Model Space in 'World' UCS, and I'm confused.. why does the 'ID'd' value not reflect whats going on when I use the vla-get-coordinates approach.
There are many other LWPolylines within the same model that behave normally.
The title says it all, Im trying to find a way to select just the vertical dimensions. Quick select doesn't work because there's no difference between a vertical and a horizontal dimension, so i was wondering if there was a LISP or something else i could do to accomplish this.
I am still green at lisp creation. I would like to create a lisp to change my cannoscale to match that of an existing dimension in model space. we use tabs and therefore have many different scales for the vports in our drawings. i want to be able to type my command, have acad ask for a annotative dimension to match, i click it, then the lisp resets my cannoscale to match.
I’m trying to create a view port, which covers my entire layout (white/ page area) using the following command
(command “mview” ‘(0 0 0) ‘(297.5 210 0))
However as you will note 0,0,0 is not the very edge corner of my layout (white area) and my white area is smaller then 297.5x 210mm (standard A4 landscape size)
How to obtain the exact measurements and starting coordinates to fully fill my entire layout page (white area)?
We have several AutoCAD drawings with hundreds of block references inserted with imprecise coordinates. Now we need to dimension all elements and need to correct these positions.
I am searching for a routine to round these positions up or down towards a 5mm precision so I don't have to manually move every single block element.
Is there any way to automate the task or do you know any workaround (like inserting the elements into a drawing with poorer unit precision settings)?
Would like to be able to select mtext explode it get x y coords of last line of text then turn it back to mtext and then launch mtext at a @0,-0.5 justification TL width 5 and display the ribbon.
All seems to work except the (command ...)
Below is my attempt.
(prompt "Select Note") (setq ss (ssget)) (command "explode" ss) (setq ss (ssget "l")) ;get last line of text
(setq ent (entget (ssname ss 0)) ent1 (cdr (assoc 10 ent))) ;get x y coords (command "undo" "1") ;set exploded mtext back to mtext (setvar "lastpoint" ent1)
I'm trying to define a grid based on polar coordinates.
Can be produced using the following MATLAB n=1:50000;r=sqrt(n);t=360/((sqrt(5)+1)/2)+1)*pi/180*n;plot(r.*cos(t),r.*sin(t),'o')
I need to insert points based on the polar coordinates defined by the equations. I knew a little bit of LISP 10 Years ago, now it's a total blank. I've been trying to write a script to make this work but after 5 days I'm still without sucess.
I wrote this small program to automate plotting a drawing to pdf. Everything work fine except I cannot figure out how to allow it to let me pick where I want the file created and what I want to call it. In this routine, the "" at the 3rd from the end place will just automatically name the file and put it in the parent folder. If I replace the "" with pause, it lets me change the name, but will not let me choose the location.
What I'm looking for is for a dialogue box to pop up (explorer style) that will let me choose a location and name the file. This is what happens if you do it "long hand" inside ACAD, how to do it in the code.
