Another dimstyle creation question

March 6

HI

I have already read through a bunch of dimstyle threads and am continuing to do so. However, my boss is breathing down my neck so I need to get the code finished and am hoping that someone here will help.

I'm working with drawings that have a large number of unnecessary dimstyles (15 or more). What I'm working on is code to find the different scales that are used and make a linear and diametric dimstyle for each scale (linear built off of Standard and diametric built off of linear), apply the new styles to all existing dimensions and purging the old styles. I've been able to build the code that goes through all existing dimstyles, make a list of the scales and remove all duplicates from the list.

Now I'm trying to make the new dimstyles. My understanding is that the way to do this is use the vla-copyfrom code. My intension is to start with the Standard dimstyle as this is a stable base to build from and modify the system variables from there. Here's where my understanding falls apart.

For some reason I can't get vla-put-activedimstyle to accept "Standard" as an input.
So I'm trying to use vla-copyfrom right away to create the linear dimstyle then use vla-put-activedimstyle to make the new dimstyle the active style.
Then I'm running a list of setvar's that don't work for whatever reason (error: bad argument type: VLA-OBJECT "Linear-1")
Should the code get this far I've got it set to try and save the new dimstyle over itself...I'm not sure this will work.
- If it doesn't I figure that I can make a dummy code, apply all changes to it then save it under the desired name.
Then I want to run through a similar set of steps for the Diametric style

Thanks for any help that comes my way.

~~is this in your assigned area of work? or did you say ill give it a shot?~~

~~"For some reason I can't get vla-put-activedimstyle to accept "Standard" as an input."~~

~~What happens when you only have one dimstyle?~~

~~it doesn't pass this if statment (if (> stylecount 1)~~
~~so scalelist is still a blank list~~
~~(foreach scale scalelist AKA (foreach scale "empty list" AKA (foreach 0 times~~
~~skips all code to generate dimstyle~~

~~"So I'm trying to use vla-copyfrom right away to create the linear dimstyle then use vla-put-activedimstyle to make the new dimstyle the active style."~~

~~(vl-cmdf "-Dimstyle" "_S" "Standard" "Y")~~

Rather then recreate the wheel use Lee Mac's Steal lisp (look at examples you can import just dim styles)

so create a drawing template with all the styles already made and then pull from that.

(defun c:Create_dimstyles (/ Drawing styleset scalelist stylescale)
  (vl-load-com)
  (vla-startundomark (setq Drawing (vla-get-activedocument (vlax-get-acad-object)))) ; sets an undo to go back 
  ;purge maybe get ride of unused dimstyles?
  (setq styleset (vla-get-DimStyles Drawing)); Gets all dimstyles in the active document
  (setq scalelist '()); Creates an empty list
  (vlax-for style styleset; Finds the scale of each dimstyle and adds it to the beginning of scalelist
    (vla-put-activedimstyle doc style); Makes the active dimstyle
    (setq stylescale (GetVar 'dimlfac)); Gets the scale of the active dimstyle
    (if (not (member stylescale scalelist)) ;just test for duplicates as you create the list
      (setq scalelist (cons stylescale scalelist)); Adds the scale to scalelist
    )
  ); End vlax for
  ;prints are for error checking
  (princ (strcat "# of styles: " (itoa (vla-get-count styleset))))
  ;(print) ;not needed
  (princ "\nList of scales: ") ;"\n" = new line in command prompt
  (foreach scale scalelist
    (princ (strcat (rtos scale 2 2) ", "))
  ); end foreach
  ;prints are for error checking
  (foreach scale scalelist
    (Steal "C:\\My Folder\\MyDrawing.dwg" (list ("Dimension Styles" (strcat "Linear-" (rtos scale 2 2)) (strcat "Diametric-" (rtos scale 2 2)))))
  ); end foreach
  (vla-endundomark Drawing)
  (gc)
  (vla-Regen Drawing acAllViewports)
); end Create_dimstyles

Bonus points use mapcar with 'setvar to set a bunch of variables with only two lines of code.

(setq vars '(DIMASZ DIMCLRD DIMCLRE DIMEXE DIMEXO DIMFRAC DIMLFAC DIMLUNIT DIMTIH DIMGAP DIMTOH DIMTAD DIMTXT DIMTXSTY DIMTZIN DIMZIN))  ;list of variables
(mapcar 'setvar vars (list (0.130 "ByLayer" "ByLayer" 0.125 0.040 1 scale 4 "off" 0.000 "off" 1 0.125 "Dimension" 12 12))) ;set new values

The if statement is easily fixed with a >= instead of =.

As nice as the steal code is I'd like to keep everything in one package because, due to the way my company works, it's going to be passed from project to project and keeping the number of files to move as low as possible will reduce the number of errors due to people not grabbing all things. This code is specific to one project type, a big one so it's worth it, so it won't be one that will get a template. Hence trying to make a dimstyle through code.

There must be a way to do what I'm asking without having to copy and paste a dimstyle from somewhere else.

Minor quibble, it's hard to read this code when a comment starts at the end of a statement. It's like the semicolon is the end of the command, which in some languages (like Java, C++, and SQL) it is. Also the expression (strcat "Linear-" (rtos scale 2 2)) shows up six times, why not evaluate it once, assign it to a temporary variable, and use that instead?

This seems to be the proper way to use vla-put-dimstyle:

  (setq newStyle (vla-item (vla-get-dimstyles doc) "aStyle"))
  (vla-put-dimstyle doc newStyle)

because why should it be simple?

That should get you back on track, but if not, check back with us.

You could start from scratch.

This rather curiously named LISP was in my library "doesntworkentmakedimstyle"

I have commented out the parts that were stopping it from working. Maybe I should rename this "thisdoesworknowbutneedssomethinkingDimStyle"

I think this is the complete list to entmake a dimstyle - not everything in this list is necessary, and it created a dimstyle "Dim_Name" just then for me.

The if statement is easily fixed with a >= instead of =.

Yes, but their is always going to be at least one dimstyle so why have the if statement if its always going to be true.

--Edit

Steven you could make it so you have declared variables to call to make the dimstyles

(defun doesntworkentmakedimstyle (Name Scale /)
  ...
  (cons 2 name)   ;Dim style name
  (cons 144 scale) ;Dim style scale
  ...
  

called with
(doesntworkentmakedimstyle (strcat "Linear-" (rtos scale 2 2)) scale)
;scale might have to be set as a double so 1.0 insted of 1

Thanks CyberAngel. It took me a bit to get things sorted but those two lines of yours were the jumping point I needed.

Noted about the comments. I'll switch for my next bit of code.

Incidentally, by "vla-put-dimstyle doc newStyle" did you mean "vla-put-ACTIVEdimstyle doc newStyle"? I ask because I could get the code to work without the change and I'm hoping that I'm not missing something.

Now I just need to figure out how to set the line colours to be "bylayer". (setvar "DIMCLRD" "Bylayer") doesn't work. 0 is "Byblock" and any number after that is a colour.

Thank you again. This is a big leap forward.

Here's the code for anyone that might need it:

(defun c:Create_dimstyles ( / acadObj doc styleset stylecount scalelist stylecount style stylescale scale unique-scalelist currentDimStyle lstylename dstylename standardstyle)
  (vl-load-com)
  (setq acadObj (vlax-get-acad-object))
  (setq doc (vla-get-activedocument acadObj))
  
  (setq styleset (vla-get-DimStyles doc)); Gets all dimstyles in the active document
  (setq stylecount (vla-get-count styleset))
  (setq scalelist '()); Creates an empty list
    
  (if (>= stylecount 1); Checks if there is more than one dimstyle
    (progn
      (vlax-for style styleset; Finds the scale of each dimstyle and adds it to the beginning of scalelist
        (vla-put-activedimstyle doc style); Makes the active dimstyle
        (setq stylescale (GetVar "DimLFac")); Gets the scale of the active dimstyle
        (setq scalelist (cons stylescale scalelist)); Adds the scale to scalelist
      ); End vlax for
      (setq scalelist (vl-sort scalelist '<)); Sorts the scales from smallest to largest
      (setq unique-scalelist '())
      (foreach scale scalelist; removes duplicates
        (if (not (member scale unique-scalelist))
          (setq unique-scalelist (cons scale unique-scalelist))
        ); end if
      ); foreach
      (setq scalelist (reverse unique-scalelist)); rea
    ); end progn
  ); End if
  
  ;prints are for error checking
  (princ (strcat "# of styles: " (itoa stylecount)))
  (print)
  (princ "List of scales: ")
  (foreach scale scalelist
    (princ(strcat (rtos scale 2 2) ", "))
  ); end foreach

  ;prints are for error checking
  
  (foreach scale scalelist
    ;Create Linear dimstyles
    (setq lstylename (strcat "Linear-" (rtos scale 2 0))); Define the style name
    (vla-add (vla-get-dimstyles doc) lstylename); Create a new dimstyle with the above name
    (setq lstyle (vla-item (vla-get-dimstyles doc) lstylename)); Define a variable for the new style
    (vla-put-activedimstyle doc lstyle); Sets the new style as the current dimstyle

    (setvar "DIMEXE" 0.125); Extension line extension
    (setvar "DIMEXO" 0.040); Extension line offset
    (setvar "DIMFRAC" 1); Fraction format
    (setvar "DIMLFAC" scale); Length scale
    (setvar "DIMLUNIT" 4); Length unit
    (setvar "DIMTIH" 0); Text inside alignment
    (setvar "DIMGAP" 0.000); Text offset
    (setvar "DIMTOH" 0); Text outside alignment
    (setvar "DIMTAD" 1); Text vertical position
    (setvar "DIMTXT" 0.125); Text height
    (setvar "DIMTXSTY" "Dimension"); Text style
    (setvar "DIMTZIN" 12); Tolerance zero suppression
    (setvar "DIMZIN" 12); Zero suppression

    (vla-copyfrom lstyle doc)

    ;Create Diametric dimstyles
    (setq dstylename (strcat "Diametric-" (rtos scale 2 0))); Define the style name
    (vla-add (vla-get-dimstyles doc) dstylename); Create a new dimstyle with the above name
    (setq dstyle (vla-item (vla-get-dimstyles doc) dstylename)); Define a variable for the new style
    (vla-put-activedimstyle doc dstyle); Sets the new style as the current dimstyle

    (setvar "DIMTAD" 0); Text vertical position
      
    (vla-copyfrom dstyle doc); copy the new dimstyle over itself to keep the changes
  ); end foreach
  
  (setq standardstyle (vla-item (vla-get-dimstyles doc) "Standard")); Define a variable for the new style

That's what I was thinking, make it into a little LISP function and when you call it send the info it needs to create the dim-style as required.

I'd have to check, some things are -1 for by block if you need that as well - need to check though

Good point. I modified it to be >= 2 so that it would go if there is more than the standard style. The other option that jumps to mind is make the condition to look for at least one style that is not labeled "standard".

As I understand it, vla-put-dimstyle adds a style to the dictionary, while vla-put-activedimstyle only makes it current... which shouldn't work if it's not in the dictionary to begin with.

But if AutoCAD uses it that way, it's the right command.

I checked, and activedimstyle does set the current style, as you'd expect. If I get some time, I'll check the other one.
