AutoCAD Visual LISP / AutoLISP :: How To Dimension Between Two Points In A Selection Set
Nov 1, 2011
Looking to make a selection set of points that are on a specific layer, and then create a dimension between, in this case, two points. I feel like it should be very simple, but I can't get it to work for the life of me. Here is the test code I've been playing around with:
Is there a lisp that will allow me to do a continuous dimension, but will alternate the dimension position from low, high, low and high? If there is no lisp already created, how to create one?
See Continuous dimension attachment for example.
I work at a glass and glazing company and this is how we dimension mullion width and DLO. See typical window dimensioning attachment for window elevation with dimensions.
I've created a lisp that draws the boltholes of a pipe flanges, using the correct number of holes, at the correct diameter at the correct bolt-hole diameter and then rotates. Everything works seamlessly, when i do just one flange. But I've discovered that fewuently there will be mulitple times when a user will have to perform the command.
So the idea I had was to do the following:
Select all circles with (setq CirclesFirst (ssget "X" (list (cons 0 "CIRCLE"))))
Go through the code to create the new circles.
Select all circles with (setq Circles (ssget "X" (list (cons 0 "CIRCLE"))))
Remove selection set "CirclesFirst" from "Circles".
But what for some reason (command "_.select" Circles "R" CirclesFirst "") does not work.
I have a drawing that has 2D pipeline (only x and y, z value =0) and 3 topo contour lines ( with x, y and z vaules). I need to divide the the 2D pipeline into say 2000 points and then get the corresponding z values from the topo contour lines. I think it can be done by interpolating between the z values for the two apparent intersection points of the 2D line and the contour lines, the x and y values will be the same for the points that falls between these two aparent intersections. Is there any lisp out there that can do that.
how I would go about writing a function that would calculate the length of a diagonal of a rectangle using SQRT function? I've been trying but so far nothing!
I have the following code, that for some reason the last created dimension is no being selected. That's the first problem. The second (and not as improtant) problem( becasue it does work), is that I'm using the "dimedit" command. I prefer to do a swap within the dxf codes, that I treid but didn't work, so I resorted to the "dimedit" command.
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 am trying to create a lisp routine, that will check the dimension style "standard" to see if its annotative. If it is, I need it to turn annotative to off.

As a consultant we grey out architectural backgrounds for our sheets. We use the SetByLayer command to change the color of the objects in our sheets to gery out. The issue is with dimsensions. Dimension Line Color, Extension Line Color, and Text Color are all set at By Block as default and no one ever bothers to change it unless they are setting it to a specific color which is even more of a problem for us. You can edit the properties of an existing dimension and set Dim Line Color, Ext Line Color, and Text Color to by layer, I am looking for a way to automate this. Something that can search through a drawing, grab all the dimensions (even in blocks) and set everything by layer.
I need to place a circle, of a user-defined radius, as a marker at the endpoints of all lines in a drawing. how to accomplish this using lisp? It doesn't matter if they overlap; I can use OVERKILL to delete those objects.
What I have is a topo plan in 3D (All contour lines have x, y and z values). My pipeline is on x and y coordinate only. I need to get the corresponding z value for say about 2000 points on the pipeline.
I need very very often to know the angle between two surfaces to write cnc programms...At the moment i draw allways two lines normal to the line between the two surfaces an use then the angle measuring tool.Works good, faster then bks and dimensioning, but need also time and always need to delete the lines after...
Is it possible to get a lisp which ask für 1 point on the first surface, 1 point on the other surface and two points on the line between the 2 surfaces? So the lisp know 3 points of each surface and can give out the angle between... Should be allways between 0-180°
So it needs only 4 klicks to get a angle! That would be so great! Is there a lisp programmer who can make this possible?
how to use AutoLISP to draw lines between two points. I have x,y,z coordinates for the end points in an excel sheet which I can save as a text file. I need to pull the coordinates from the file and use them to draw the lines. There are 2000+ lines so it is not feasible to draw them manually.
I am trying to get the end points of an invisible line it would be the line that you offset I know all about polar I just don't know which angle to add or subtract and I will pick the point on the side I want it to be on I am going to pick 2 lines and I want them to offset invisible lines in the middle the lines are not parallel.
My goal is to be able to select a line and a dimension and then have the line's length appear as the text override for the dimension. I have the code to substitute the variable "dist" for the dimension text:
but am having problems extracting the line's length to the variable and setting setting it equal to the variable. To make things more interesting, the value needs to be in inches with fractional inches accurate to 1/16".
I'm dimensioning an old drawing with the real (measured) dimensions and with the drawing dimensions in brackets (using ' 1500 (<>)' to give '1500 (1505)' for example.
What I'd like is to also be able to put on the difference between the length I type in and the length in brackets - as this would let me see any really glaring errors that can't be attributed to user-error on the laser measure.So I could type in '1500 (<>) (X)' where X is the formula, and get ' 1500 (1505) (5)' back?
How to be able to run a script that could highlight any dimensions where the number is brackets and the typed number have a a difference of, say, 50.Or failing that, any way to extract all the dimension text at the end into excel so I can see the differences myself?
Found this routine online and am hoping to modify it to my needs, just not sure how to proceed.
It exports the text out of the dims into an excel file, the issue I have is that it automatically opens a new book every time you run the lisp with the original workbook open.
I am trying to get it to automatically insert the next set of numbers on the row below the first pull.
Currently, when I do drawings, I give my machinists drawings with each point, and they program their machines. To do that, they calculate the round part diameters, which is basically 5" - 2x<Dim>.
I'd like it if I could give them drawings with the real number, and in parenthesis next to it, 5-2x<Dim>.
I've attached a jpg of what I normally give them and how I'd like it to look. Is this something do-able via a macro or something?
We have a need to select a tangent line/polyline etc and then select two other points we would then like to have the program draw an arc through the two points and yet still be tangent to the initial line/polyline that we picked. We don't care what the radius is as we believe there is only one solution anyway. It would be wonderful if we could just use the Arc command and select start>Second Point> then just use the Tangent Osnap but I guess that is out of the question :-)
The only code that I have come across that even resembles this only allows for one point not two (STILL VERY HANDY AND VERY SLICK)

[Code]....
How does everyone else hande this? By they way... I dont care what language it is written in :-)
I am using autocad 2013 and importing PDFs into the drawing and recently the OSnap points within the pdf are missing. The PDFs are of floorplans and I was able to measure from wall to wall using endpoints and midpoints. Now I am only able to select the endpoints on the frame of the pdf.
Is there a switch that might have been turned off?
