Nothing I can think of that’s built in, so you would have to roll something. With lisp, you would use an event to update the attributes, i.e. attached to regen There’s more options with ARX, .NET or Python - Create your own custom field - Create an Overrule that updates the attributes on close

Bogging down? Why would it be bogged down? And you think this is simpler than just placing the LISP file in a specific folder without needing to add (load "My lisp") to your one LISP file?

I can't figure out how to draw the 3d model shown in the image sent. It is fig 15.47 shown upside down.

I can't figure out how to draw the 3d model shown in the image sent. It is fig 15.47 shown upside down.

I probably can not help, but post a sample dwg so others can look at it.

Yeah, I can easily do a lisp but I don't want to have my engineers have to run a lisp every time for this workflow. I'm trying to have detail numbers auto populate based on where the detail title is located. So if the detail title attribute is in a specific area of model space, it will always be 1/S3.0, etc

So if understand correctly you want to place a field value which says "This is inside area1 " You can certainly do as a lisp updating a value but not as a field. Not sure if you can do a COND in a field expression say looking at a multiple XY points.

I'm attempting to make a block with an attribute/field that when placed inside a pre-defined set of 4 coordinates (rectangle), the attribute field will update with a custom message. Anyone have any guidance with this? I'm guessing it will need a diesel expression, which I'm not all that familiar with. I'm hoping this is the right forum since it involves coding an expression Thanks

I'll investigate. Any suggestions?

Sorry Lee used the Start up suite for years stayed away from the Acaddoc etc, of course in Bricscad the files are different names again. Have used this for years and I think simpler as you can load custom lisp files rather than bogging down the default acad****. I dont understand you can load 50 files via one, yes ONE lisp file added to the startup suite, its just a case of having a (load "My lisp") line in the file for each lisp file. Again I refer to the AUTOLOAD function, this will get ready to load any of the 50 lisps on demand. I have 35 autoloads as part of my single custom lisp. As well as lots of defuns. By using autoload you conserve memory. Yes set the support path to point to your lisp directory and move it up to the top line.

In Bricscad its known as "BLADE".

Using massprop in a lisp is easy you just write it to a file then read what you want out of that file and display. Just always write to a known file. Just a question would the answer not be Litre's. (defun c:vol ( / ent vol) (setq ent (car (entsel "\nPick a solid "))) (command "massprop" ent "" "Y" "D:\\acadtemp\\solid.mpr") (setq fo (open "D:\\acadtemp\\solid.mpr" "R")) (repeat 3 (setq vol (read-line fo)) ) (setq vol (read-line fo)) (close fo) (vl-file-delete "D:\\acadtemp\\solid.mpr") (alert (strcat vol)) (princ) )

Rather than a field it can be done by finding the text removing not wanted part, then updating the attribute in the title block, the only stumbling block is it will work easy if the label is in a consistent X&Y location in every layout. No dwg posted so no answer. Need a few layouts.

Oh I'm not mad, I just think you're blinkered into using the Startup Suite. As I've suggested throughout this thread, I would use the acaddoc.lsp. In my acaddoc.lsp, I have the following basic code: ( (lambda ( d ) (foreach x (vl-directory-files d "*.lsp" 1) (if (/= "acaddoc.lsp" (strcase x t)) (load (strcat d "\\" x) nil) ) ) ) "C:\\YourLISPFolder" ) Then, whatever .lsp files I place in "C:\\YourLISPFolder" are automatically loaded on startup - no need to change the Startup Suite, no need to modify the acaddoc.lsp any further - just drop a file into the folder.

There is also Lee Macs Box Text function for another option...

I think this one does dynamic columns as well: mtxtWdtHt (defun c:mtxtWdtHt ( / textss ) (setq textss (ssget '((0 .

Not quite what you want but I have this line on opening a file: (setvar "MTEXTCOLUMN" 0) ;;Dynamic columns OFF Just in case someone has been using columns. Just a setting, won't alter existing texts Might be an edit - have a memory of making something up EDIT: Strip MText (SMT) clears columns... need to look at how

There is a good program for MLEADER and MTEXT, author KoMon reset_mleader_mtext.fas

Here is one I did a while back for the WIDTH only. (I'll see if I can add the height as well.) NOTE: This doesn't work well with Annotative MTEXT, and it will not work if the columns are set to "dynamic"; must be set to "No Columns". (see screenshot). (defun c:MTWID (/ _StrParse d dw obj ss tls txt wid) (vl-load-com) (vla-StartUndoMark (setq d (vla-get-activedocument (vlax-get-acad-object)))) (defun _StrParse (str del / pos) (if (and str del) (if (setq pos (vl-string-search del str)) (cons (substr str 1 pos) (_StrParse (substr str (+ pos 1 (strlen del))) del)) (list str) ) ) ) (princ "\nSelect MTEXT Objects: ") (if (setq ss (ssget '((0 . "MTEXT")))) (repeat (setq n (sslength ss)) (setq obj (vlax-ename->vla-object (ssname ss (setq n (1- n)))) txt (vla-get-textstring obj) dw (vla-get-width obj) ) (if (> (length (setq tls (_strparse txt "\\P"))) 1) (setq txt (apply 'strcat (cons (car tls)(mapcar '(lambda (x)(strcat " " x)) (cdr tls))))) ) ;; get the width of the longest text string (setq wid (apply 'max (mapcar '(lambda (x / y)(setq y (textbox (list (cons 1 x))))(- (car (cadr y)) (car (car y)))) tls))) (vla-put-textstring obj txt) (vla-put-width obj wid) ) ) (redraw) (vla-endundomark d) (princ) ) If someone can figure our a way to scale properly with annotative text and turn off columns programmatically, then it would be good to add.

There is an easier way (m-r @Lee Mac don't get mad ). Create a separate folder for files that need to be added to the startup. And in the "Load/Upload Applications" window, click "Add..." and open this folder. Select all the files in the folder and click the "Open" button. All files will be uploaded to the Startup Suite. A good idea comes after

If I understand correctly, you can't do this with standard AutoCAD tools. You need to associate each label with its perimeter and its neighboring boundary. To do this, you'll need to break each perimeter down into individual polylines. Each perimeter section shared by two labels must be a separate polyline. Start by figuring out how to achieve this.

Thank you! But my goal is a lisp that would automatically set up the width and height to match the text shown without any input from me.

I've edited the code so that, upon completion of the command, the "ListaLisp.lsp" file opens with Notepad. Try again. PS: "ListaLisps.lsp" file must have been created. Otherwise, the subsequent messages would not have appeared.

@Nikon My 2c .. place all your lisp files in a subfolder under "MYDOCUMENTS". Then you don't have to worry about permissions, AutoCAD version or usernames. (strcat (getvar "MYDOCUMENTSPREFIX") "\\LISP") Then add this to your support paths and DONE!
