You are here: Home / AutoCAD / Automatic AutoCAD dimension. Name: HTLDimSpace; Description: This command will automatically space a dimension at 3/8”. This has nothing to do with your nice Lisp pushed macro.

AutoCAD Visual LISP / AutoLISP :: Continuous Dimension Lisp That Alternate Its Position

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.

AutoCAD Visual LISP / AutoLISP :: Changing Text In A Dimension

I want to override the measurement in a dimension with a string of text using a LISP command.
E.g. 'select dimension'
type new text for dimension
replace dimension measurement with new text. I can get the entity and its values, buy not sure which value to change for the 'text override'.

AutoCAD Visual LISP / AutoLISP :: Draw Rectangle Dimension?

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!

AutoCAD Visual LISP / AutoLISP :: Select Last Created Dimension?

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.
(command 'DIMLINEAR' pause pause pause)
(setq last_dim (entsel (entlast)))
(setq oldunits (getvar 'lunits')) (setq oldprec (getvar 'luprec'))
[Code]...

AutoCAD Visual LISP / AutoLISP :: Dimension Styles Colors

Is there any way to change the colors of the dimensions styles, including dimension lines, extension lines and text to 'by layer'
I found a code to change the colors, but only affects the current dimensions in the drawing and the styles do not change.

AutoCAD Visual LISP / AutoLISP :: Get Coordinates For Dimension Arrowheads?

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?

AutoCAD Visual LISP / AutoLISP :: How To Dimension Between Two Points In A Selection Set

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:
(defun c:test (/ sel1 TC)
(setq sel1 (ssget 'X' '((8 . 'VPOINTS'))))
(setq TC (polar (entget (assoc 10 (ssname sel1 0))) (dtr 180.0) 9))
(command 'DIMLINEAR' (entget (assoc 10 (ssname sel1 0))) (entget (assoc 10 (ssname sel1 1))) 'V' (polar TC (dtr 180.0) 9) ')

AutoCAD Visual LISP / AutoLISP :: Set Dimension Style To Annotative Off?

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.

AutoCAD Visual LISP / AutoLISP :: Dimension Color By Layer

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.

AutoCAD Visual LISP / AutoLISP :: Line Length To Dimension Override?

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:
(setq dimselected (entsel '
Select Dimension:'))
(setq newlength dist)
(command 'dimedit' 'n' newlength dimselected ')
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'.

AutoCAD Visual LISP / AutoLISP :: Additional Counter For Layer Dimension

if my attach lisp can add sort of counter that how many dimensions, leader and multileaders have been move to layer 'dimension'..

AutoCAD Visual LISP / AutoLISP :: Any Way To Extract All Dimension Text At End Into Excel

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?

AutoCAD Visual LISP / AutoLISP :: Dimension Export Routine Modification?

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.

AutoCAD Visual LISP / AutoLISP :: Add Calculated Text To Ordinate Dimension

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?

AutoCAD Visual LISP / AutoLISP :: Auto Dimension Closed Polyline

Is there a command or a lisp that will automatically dimension each side of a closed polyline at once? See attachment for image.

AutoCAD Visual LISP / AutoLISP :: Dimension Building - Labeling Multiple Lines At Once

How to write an AUTOLisp program to label building dimensions. With Civil3d 2013 preventing me from labeling multiple lines at once, creating building labels to dimension complex building exteriors is much more complicated than it needs to be. Lisp Routine that Generates a MText or Dtext dimension centered on a line and offset to be clear of the line. the layer for this piece of text would always be 'DIMS-BLDG' and the text style will always be 'L50s.'
the text doesn't have to be organized as it is in this example. the main focus is the layer being correct with the foot mark, precision set to xx.x and oriented to the line.

AutoCAD Visual LISP / AutoLISP :: Routine To Alert To Overlap Dimension Lines?

Sometimes someone dimensions a floor plan and starts one direction and then 'goes back ' the other way over the top of the dimension they just placed, which causes the dimension lines to overlap, which in turn shows incorrect distances when viewing on paper. Any lisp routine that can alert you to the fact that there are overlapping dimension lines (not the extension lines) in a drawing by changing them to color White or something? I have pasted a routine that we use which changes all dimenions with 'modified text' to color white. That way I can see if someone just typed in the dimension distance they wanted instead of what was actually there.
(defun c:dc (/ dim_length)
(setq ssmod (ssget 'X' (list (cons 0 'Dimension')(cons 1 '~'))))
(if ssmod
(progn
(setq dim_length (sslength ssmod))
(command 'Change' ssmod ' 'P' 'C' 'w' ')

AutoCAD Visual LISP / AutoLISP :: Double Click Dimension For DIMRND Override

I want to doubleclick on a dimension and have the DIMRND override appear
I can't figure out what command I need to customize the doublclick CUI

AutoCAD Visual LISP / AutoLISP :: Creating Stacked Fractions For Dimension Override

I wrote the code below (allow the user to pick points in different viewports and then override an existing dimension's text with the difference in X values. The (hopefully) last issue is that the fractions should be vertically stacked and at 100% text size.
(defun c2text ()
(command 'mspace')
(setq p1 (getpoint 'Select left point '))
[Code]..

AutoCAD Visual LISP / AutoLISP :: Set Dimension Text Fill Color To Background

I would like to set dimension text fill color to 'background' instead of, you know, dimensioning my drawings properly.
I have this code I got on these forums and it works well except for the 'TextFillColor' variable. I can't find the correct color number or syntax for 'Background'. It's currently set to 0 which produces ByBlock, and any number I put in there corresponds to the AutoCAD color number (1 = Red, 2 = Yellow, etc.)
If you have a better routine that you could post that works for me too. Or maybe you could just do my work for me? Even better.
(defun c:test (/ obj num cnt)
(vl-load-com)
(setq ss1 (ssget '((0 . 'Dimension')))
num (sslength ss1)
cnt 0)

AutoCAD Visual LISP / AutoLISP :: Adding Numbers In Sequence Underneath Dimension Lines

I have an opportunity to make a good impression at a new job, but ive never had the initiative to learn how to write a lisp routine. at my work we make walk-in coolers and freezers. these coolers are modular with a standard wall piece measuring a certain length. these wall sections have to be numbered sequentially. is there any way to automate this? sometimes we get change order from the client and it means going back and manually changing multiple texts (sometimes in the hundreds), but i thought if there was a way these wall sections could be scheduled somehow that when a new wall panel is inserted in the beginning of the sequence it would update everything after it automatically.

AutoCAD Visual LISP / AutoLISP :: Add String To Each Item In List Using Lisp

I have a list ('temp.dwg' 'temp2.dwg') and would like to add the string 'insert text here' into each item in the list resulting in ('insert text heretemp.dwg' 'insert textheretemp2.dwg'). how would i go about doing that using LISP?

AutoCAD Visual LISP / AutoLISP :: Opening Drawings With Default Visual Style Set To 2D Wireframe

Is there a way to programatically set a visual style before a drawing actually opens?
We have some huge models and people seem to forget to change their visual styles back to 2D wireframe before saving and exiting drawings. Some models will crash on some workstations when trying to open in a rendered mode.
I found a lisp with a function that looked to set viewport visual styles. But it does not seem to be supported anymore. --> (vla-put-VisualStyle vport 1)

AutoCAD Visual LISP / AutoLISP :: Write A Lisp Routine That Invoke The Mleader Command

I'm trying to write a lisp routine that, when I invoke the mleader command, osmode is set to 'nearest' & orthomode is set off. I then would like the original settings to be returned.
attached is what I have written so far:-

AutoCAD Visual LISP / AutoLISP :: Visual Effect Settings?

Lisp that switches back on Selection Preview i.e. thickens and highlights lines when you hover over them?I don't know why, but they are always unticking the boxes.

AutoCAD Visual LISP / AutoLISP :: Combinations In DCL?

Is it possible to execute a certain command based on multiple selections withinin a dcl? for example: two radio colums, one with selections A and B, and a second with selections 1 and 2. is it possible to program commands based on user selections from each column? ex: if A and 1- do a command. A 2- do a different command, etc..
I tried :
(action_tile 'key1' '(setq A t')
(action_tile 'key2' '(setq B t')
(action_tile 'key3' '(setq 1 t)(done_dialog)')
(action_tile 'key4' '(setq 2 t)(done_dialog)')
(if
(and (a) (1)
)
(command ..
but was unsuccessful. no matter which combination was selected, the command under all combinations would run.

AutoCAD Visual LISP / AutoLISP :: Get Attribute Value

I am trying to find a lisp that would get an attribute value (tag name = NBR_5) . I'm trying to run a simple routine that would let the user place the value from the titleblock attribute as text on a drawing. I see a ton of articles regarding getting attributes but I am not well versed in programming.

AutoCAD Visual LISP / AutoLISP :: Nil At The End Of Command

I have a routine that work fine, but I receive a nil at the end of command. How to fix that?

AutoCAD Visual LISP / AutoLISP :: 3D Point From X And Y?

I'm trying to find acceptable point values to feed to the vlax-3d-point function for a vla-addmtext function. With vanilla lisp I just provide the point as x y = '7/32' '2-3/8'. So I assumed that I could drop a 0 in for the z like: (VLAX-3D-POINT '7/32' '2-3/8' 0).
Then I thought I was going to be tricksy and try (vlax-3D-point (getpoint)) believing that I could pick the point and get what I need to feed the function, but yet again, no deal. The command line gave me:
node
of #<variant 8197 ..>
Nothing I can use in my code. So how do I find the point in a format that vlax-3d-point will like?

Another great tips from Hai Le (@ThatCADguy).

This double click feature allows the user to space an individual dimension (accordingly to the MMI 3/8” spacing standards) by double clicking a neighboring dimension. The following steps will guide you through a series of instructions to create this feature.

By default, DIMSPACE command allows you to input the distance manually or choose auto. Auto distance will give you distance 2x of text height. Now we will see how you can change it to 3/8”. The are various ways to place this custom command, like in toolbar, ribbon panel, or context menu (right click). In this tip, we will use it in double click action.

1) Execute the Customize User Interface dialog box by typing ‘CUI’ into the command line.

2) Create a new command. If you are not familiar with creating new command in CUI, refer to this article: Exploring AutoCAD CUI: Creating a command.

3) Fill out new command Properties. (See image below)

• Name: HTL_DimSpace
• Description: This command will automatically space a dimension at 3/8” times the scale factor from a selected dimension. (Optional)
• Command Display Name:
• Macro: ^C^C_dimspace;(SETQ DS (GETVAR “DIMSCALE”)G:TS (* 0.375 DS));

4) Find the Double Click Actions tab under Customization in All Files and drag your new command from the Command List into the option labeled ‘Dimension.’

Now try to double click a dimension then click another dimension as base. You will see the dimension space is adjusted to 3/8” (or 0.375).
