I'd like to run one command that allows the user to draw a polygon viewport then sets that VP to 1/8"=1'-0".
It can be nearly accomplished with a macro, but falls just short because the polygon vp requires an unknown number of clicks, so there is no way to know how many pauses for user input in the macro.
I am adapting a routine by Alan J Thompson found here for placing an outline of a paperspace viewport in modelspace.
I have added some lines for making a suitable No plot layer with appropriate linetype, and wanted to make the lwpolyline have a thickness dependent upon the viewport scale.
My paperspace viewport scales are set for printing via Zoom - 1/50XP for example to get a 1:50 scale plot (or 0.02XP)
Having selected the relevant viewport, I wanted to be able to determine the vp scale, but am unsure how to extract this information from the viewport entity itself.
The routine was as follows:-
(defun xpfact ()
(- (car (trans '(1 0 0) 2 3))
(car (trans '(0 0 0) 2 3))
)
)
--
calculation a viewport scale of 1"=30'.
I've looked around and only find nearly what I looking for. For 1"=20' I have a value of 0.004167 Paper Units = 1 Drawing Units, but what is the formula to calculate 1/30"=1'-0"?
I have a series of drawings that are currently in modelspace. What I have to do is
1) Insert a new border in paperspace.
2) create a viewport and place the view in modelspace into it.
I am trying to use the command -vports but get an SPPROCESSQUEUE error wghen I use lists such as this:
(command -vports (list 0.625 23.59375) "" (list 35.4375 2.625) "")
I've had a simple lisp I've been using for years that suddenly disappeared. It required that you identify a block name, tag name, and the value that you want the tag to be. All of this is performed via command line, so it is scriptable. Since I lost it, I've been experimenting with -attedit. This command comes frustratingly close to what I'm looking for, except it only appends an existing tag, or replaces a specific string within the tag; I can't get it to replace the entire tag, regardless of its value.
1> Any lisp routine that does what I describe?
or
2> How to make -attedit replace a tag value without regard to what the value currently is (like a * wildcard)?
I have double line pipe drawings but i have to change distances between of this lines in entire drawing and i was thinking that maybe there is a lisp code which can create new double line according to my specify dimensions ...
example :
Distance between lines : 100 mm
------------------------
------------------------
here is what i want to do :
1. select double line
2. specify new distance ( for example 200 mm)
3. lisp will create center line middle of the selected lines ( maybe it can ask me that this center line will be permanently or not )
4. lisp will create new double line from this centerline according to my specific distance
5. new double line layers will be the same with selected old double line
and this lisp has to work for double arc or quarter circles too.
I need a lisp that creates a polygon of N points, so to enter a only the distance between these points, after choosing N points in the drawing for approximately creating polygons.
View 7 Replies View RelatedI'd like to get areas from all closed loop polygons of my drawing and save them.
From my point of view, the function would be to:
- hatch every polygon of my drawing
- for each hatch do
- extract area and put it in an array with the variables (name of polygon and area).
And then is it possible to save it in a DWG or DXF file in order to reuse these areas by another program ?

I have a window schedule lisp routine that places a 6-sided polygon around text that label each window. I want to change the code so that its a circle instead of a polygon. Here is the code line that needs to be modified:
(command "polygon" "6" "fro" (cdr (assoc 10 (entget templine)))(strcat "@38,-" (rtos (+ (* linecount 18) 14) 2 0)) "C" "6")
I am working on automating page setups in model space and am looking for a way to set the plot scale equal to the annotation scale for scaled drawings with
(setvar "filedia" 0)
(setq a (getstring (getvar "cannoscale")))
(command "-plot" "YES" "MODEL" "" "" "" "" "" "" !A "" "" "" "" "" "" "_Y" "_N")
Setting the plot scale with !A causes the lisp to fail. However, when running each prompt through the command line individually, !A works fine. what is missing?
How would I go about this. if a two blocks or polygons are overlapping area?
A good method or the algebraic formula for a function to tell me if a point is inside a polygon or block's area?
I really need a auto lisp that do lines/polyline on line edges creating a polygon like the example.
View 8 Replies View RelatedI would like to find a lisp that changes the scale of something that has an annotative scale and deletes all other scales in the object scale list. Often i have many different scales of existing dimensions or objects. i waste a lot of time opening the annotation object scale dialogue box, selecting add, finding my scale and deleting the old scale.
View 3 Replies View RelatedI need to delete a specific block from current opened drawing by LISP command.
for example removing XREF attached is very easy:
(COMMAND "-XREF" "D" "FRAME")
I can remove "FRAME" XREF from drawing. Now, I want to delete a/all block with "TB12" name with same action!
(command "BlockDelete" "TB12")
so, how can I delete a/all block with specific name in current drawing?
How would one modify
(= (cdr (assoc 0 data)) "ATTRIB")
in order to filter for a certain attribute tag named MYTAG
I am working with a custom LISP routine which reports out to a CSV file, an attribute extraction file - but I need my routine to ONLY evaluate blocks which have the MYTAG attribute tag. Then, if it passes that first check, it evaluates another list of Tags within those blocks - a list of tags which I have specified elsewhere in the code.
I am trying to modify my existing code as little as possible, and I think that if I do it at the line (which I've pasted above) - that will "pre-qualify" my selection set....
ATTACHED LISP IS THE FILE I AM WORKING WITH --- THE ACTUAL LINE I WANT TO MODIFY IS AT:
"(while (eq ENSUB "ATTRIB")"
I'm trying to regen a viewport with Visual Lisp, with this code
(setq acadobject (vlax-get-acad-object))
(setq activedocument (vla-get-activedocument acadobject))
when I issue the next code
(vla-regen activedocument acActiveViewport )
I get the following error
*** ERROR: AutoCAD: AutoCAD is currently busy.
What is missing in my code?
I have some code that starts a new drawing with a specific template from a lisp routine
(defun ghd:load_newdwg (template / ae-acad-object newdwg)
(setq ae-acad-object (vlax-get-acad-object))
(setq newdwg (vla-add (vla-get-documents ae-acad-object) template))
(vla-put-activedocument ae-acad-object newdwg)
)
The template location and file is stored in variable clienttemplate (and is not the standard template path set under options). All works okay except if I close the new drawing, when I return to the previous drawing that was current when the new drawing was created (i.e. the drawing that the routine was run from). I get the following error:
Command: ; error: Exception occurred: 0xC0000005 (Access Violation)
; error: Unknown exception occurred
; warning: unwind skipped on unknown exception
I assume this has something to do with the original routine not closing/finishing before switching to the new drawing. This is the last line of the routine:
(cond ((= startnewdwg 1) (ghd:load_newdwg clienttemplate)))
I need a lisp which is i can draw a line or pline with circle in every 30 meters ( circle diameter and total line or pline length will be optional )

I would like to insert a block in a specific layout (eg. "LAYOUT13") using the function vla-insertblock
I have already searched the web and this newsgroup but have not found the solution.
how to quick select all the blocks from a specific layer (for instance XPTO) and export them along with their attributes, exactly as we do by quick selecting them and then, through AutoCAD Express -> Attribute Export Info, but in a script...
View 9 Replies View RelatedIs there a LISP code for disabling OSNAP for specific objects or layers? An automatic disable for multileaders would be useful when fine tuning the text placement. Trouble is you need the snap for the leader end. Maybe you could disable the snap for the text grip only.

i can calc the major and minor and i have a polar point of where it should be drawn.
i just need the code to draw the ellipse.
I currently have a LISP routine that will replace the value of a specific attribute name with sequential numbers in the order that the blocks are selected. Like TCOUNT for attributes - and it only looks for a specific attribute Tag Name called "ID".
However, what I want it to do now, instead of just putting the number into the attribute value, I want the number to be a suffix to the existing default tag value of the tag named "ID" which is "ADDRESS:" for some blocks and "ELEVATION:" for other blocks but the tag name that the routine always has to filter for is "ID". That way the user can pick anywhere on the block - not being forced to pick the tag we want to add numbers to.
What I need the new LISP to do is append a space and then a number to the existing tag value in the block, so that the result would look like "ADDRESS: 1", "ADDRESS: 2", "ADDRESS 3" or "ELEVATION: 1", ELEVATION: 2", etc. depending on whatever the default value for the tag "ID" is.
there are several hundred different block names - but they all have a Tag Name of "ID" - whose default value is sometimes "ADDRESS:" and sometimes "ELEVATION:".
If you do a LIST command on a dynamic block... AutoCAD tells you the Block Name as well as the Anonymous Block name.
How can I use ssget to snag all Dynamic Blocks that use the 'Real Block'?
I'm looking for a way to find out what all plot styles are set in drawings in a sheet set.

View 9 Replies View RelatedI'm trying to create a field in a block (titleblock) that will automaticly update when I change the viewportscale.It's mostly only 1 viewport, sometimes a second of even 3rd but, they are not important to the titleblock.
I've read aboud fields and diesel expressions. I've tried and it works. there is only 1 problem,It only works with the object (when field expresssion, object, custom scale) in this case the viewport pressent at that time.
When i use the same field with the same expressions, it does not recognize the viewport/object.Is there a way to make the field, diesel expression or even something else, work without it's need for a
object name. Perhabs that the expression gets the viewportname from a lisp, something like: (setq ss(ssget "X")) ;some thing like this Can it be done?
Further to my earlier topic for getting the viewport scale which has been nicely solved, I am looking for a way to get one of the corners of the viewport outline 'drawn' in modelspace so that I can add the name of the spcific layout Tab to which it relates in a location that suits the drawn outline.
The code that I am adapting came from the thread titled Outline projection all viewports to model..The routine appears to pick up the corners of the viewport in paperspace and tranform/translate them to modelspace co-ordinates.
(defun _trans (p) (cons 10 (PCS2WCS p ent))) (defun _cornersFromBBox (o / a b) (vla-getboundingbox o 'a 'b) (setq a (_trans (vlax-safearray->list a)) b (_trans (vlax-safearray->list b)) ) (list a (list (car a) (cadr a) (caddr b)) b (list (car b) (cadr b) (caddr a))) ) (if (setq ss (ssget '((0 .

I have redined AutoCAD's copy command alias to C, but to also do other things, like set a few important variables in the background. One of the lisps I've incororated are making new viewports, that also create layers that are visibly specific to the viewport being created.
We were tasked a while ago to do an easy job of copying entities (dimensions, text and what not) in a layout. The problem is, users are copying the viewports too, which is bit more ineffificent than using the create viewport command I developed.
Is there a way to see if a selection set includes (0 . "VIEWPORT") entities? If the check returns nil, well then all is good. If the check returns "true", then I can prompt the user that a "VIEWPORT" entity is selected. I can then exit the command, or ask the user if they are sure they want to copy the "VIEWPORT" entity.
