I'm new to LISP in autocad. The code shown below draws circles (with radius of 1) in a sloped line. What I don't understand is the value of "a" does not increase in increments of 1. The center of the circle drawn in autocad is (1,1) , (1.7071,1.7071) , (3,3) , (3.7071,3.7071) , (5,5) ... Can someone pls. explain why?
(defun c:wwq ()
(setq a 0)
(while (< a 10)
(setq a (+ 1 a))
(setq pt1 (list a a ) )
(command "circle" pt1 1 )
)
)
While using the AutoLISP command function, you have to care about active object snaps.
One way is to force object snaps to "none" within the (command ...) expression:
(defun c:wwq (/ a pt1)
(setq a 0)
(while (< a 10)
(setq a (+ 1 a))
(setq pt1 (list a a))
(command "_circle" "_none" pt1 1)
)
(princ)
)
Or, you can deactivate every osnap by setting the OSMODE system variable to 0 at the begining of the code and retore the previous value at the end (to be really safe, this method should need and error handler to insure the the previous value is reset in case an error occur during the code execution).
(defun c:wwq (/ a pt1 os)
(setq a 0
os (getvar 'osmode)
)
(setvar 'osmode 0)
(while (< a 10)
(setq a (+ 1 a))
(setq pt1 (list a a))
(command "_circle" pt1 1)
)
(setvar 'osmode os)
(princ)
)
Another way is to use the entmake function which is faster and do not care about osnaps.
(defun c:wwq (/ a)
(setq a 0.0)
(while (< a 10.0)
(setq a (+ 1.0 a))
(entmake
(list
(cons 0 "CIRCLE")
(list 10 a a 0.0)
(cons 40 1.0)
)
)
)
(princ)
)

I'm creating some AutoLisp commands for my team, and now that I'm finished, the code breaks apart in their computer and I can't figure out why. Works fine in mine.
The idea of the code is to stretch a polyline and update the block attributes that is grouped with.
The code asks to select the block, the actual width of the polyline and the fraction that is is supposed to take (ex: 0.75 to reduce to 75%).
Then, and here is were the problem starts, select the sides to stretch. On their computers, he does not allow to select, it simply jumps ahead.
(defun c:MRV (/ a b c d e)
;ungroup
(command "pickstyle" 0)
;variables
(setq blk (entsel "\nSelect block to modify: "))
(initget (+ 1 2 4))
(setq a (getreal "\nWidth?"))
(initget (+ 1 2 4))
(setq b (getreal "\nNew module fraction? (>0;1<)"))
;distance to reduce
(setq c (- 1 b))
(setq d (* a c -0.5))
(setq e (* -1 d))
;stretch
(command "stretch" pause pause "" "0,0" (polar '(0 0) (/ pi 2) d))
(command "stretch" pause pause "" "0,0" (polar '(0 0) (/ pi 2) e))
;open layer
(setq LayerTable (vla-get-layers (vla-get-activedocument (vlax-get-acad-object))))
(if (and (tblsearch "LAYER" "MC_BLOCO_INFO_AREAS")
(setq layname (vla-item layertable "MC_BLOCO_INFO_AREAS"))
(= (vlax-get-property layname 'lock) :vlax-true)
)
(vla-put-lock layname :vlax-false))
;change attribute
(setq l (cons "CAMPO_6" (rtos b 2 2)))
(LM:SetAttributeValues (car blk) (list l))
;close layer
(setq LayerTable (vla-get-layers (vla-get-activedocument (vlax-get-acad-object))))
(if (and (tblsearch "LAYER" "MC_BLOCO_INFO_AREAS")
(setq layname (vla-item layertable "MC_BLOCO_INFO_AREAS"))
(= (vlax-get-property layname 'lock) :vlax-false)
)
(vla-put-lock layname :vlax-true))
;update block width
(command "regenall")
;regroup
(command "pickstyle" 1)
(print "Modulo modificado.")
(princ)
)
(defun LM:SetAttributeValues ( blk lst / enx itm )
(if (= "ATTRIB" (cdr (assoc 0 (setq enx (entget (setq blk (entnext blk)))))))
(if (setq itm (assoc (strcase (cdr (assoc 2 enx))) lst))
(progn
(if (entmod (subst (cons 1 (cdr itm)) (assoc 1 enx) enx))

What should be happening:
When the AutoCAD STRETCH command issues the prompt for a selection of objects selected using a crossing window (crossing the segments that are to be stretched), the prompt is a standard selection prompt and the STRETCH command will subsequently obtain information about how the selection was acquired in the same way as you might using the AutoLISP ssnamex function.
As such, I would suggest supplying the STRETCH command with a selection set which has already been acquired using a crossing window selection method.
For example, you might define a function such as:
(defun mystretch ( dis / pt1 pt2 sel )
(while
(and
(setq pt1 (getpoint "\nSpecify first point of crossing window: "))
(setq pt2 (getcorner pt1 "\nSpecify opposite point of crossing window: "))
(not (setq sel (ssget "_C" pt1 pt2)))
)
(princ "\nNo objects were found within the crossing window.")
)
(if sel
(progn
(command "_.stretch" sel "" "_non" '(0 0) "_non" (list 0 dis))
t
)
)
)
You can then evaluate the above function with the distance that you wish to stretch the objects in the Y-direction, e.g.:
(mystretch 10.0)
Or, using the variables in your code:
(mystretch d)
(mystretch e)
The function will then return t (True) if the user has supplied two valid points and the STRETCH command has been issued - you can test for this in your program before proceeding.
Using this approach you can ensure that the user has supplied two points defining a crossing window which intersects one or more objects prior to issuing the AutoCAD STRETCH command.
The use of the ssget crossing mode string (C) also ensures that you are always supplying the STRETCH command which has been obtained using a crossing selection method.
You may also wish to refer to this answer regarding the use of the _non object snap modifier and also the _. command prefix in the above example code.
I have a lisp written that involves setting a variable, then selecting points inside of a loop. Once I decide that I am done selecting points, I would like to be able to revert that variable back to what it was originally when I press the escape key.
eg.
(defun c:df ()
(setq oom (getvar "osmode")) ;store current state
(setq type(getint "\nEnter Type: 1 For Horizontal, 2 For Vertical : "))
(setq startpt (getpoint "\nChoose Start Point : "))
(setq ptx (+ (nth 0 startpt)10))
(setq pty (+ (nth 1 startpt)10))
(setvar "osmode" 2); change state state
(while
(setq nextpt (getpoint "'Pick Mid: ")) ;make selection
(if (null nextpt) ((princ "\nNull Value Error.") return))
(if (= type 1) (command "dimlinear" startpt nextpt "H" (list 0 pty) ))
(if (= type 2) (command "dimlinear" startpt nextpt "V" ptx ))
(setq ptx (+ 5 ptx))
(setq pty (+ 5 pty))
)
;do after escape key is pressed.
(setvar "osmode" oom) ;revert state back to original.
)
I have found possible leads to do with "User Input Errors" but couldn't really get anything to work. To my understating, when escape is pressed lisp just exits and doesn't finish executing.
Thanks in advance.
AutoLISP considers a cancellation an error.
You can therefore manage the cancellations with an error handling. AutoLISP provides the *error* function that can be locally redefined.
In addition, I would like to make a few recommendations:
do not use the type symbol for a variable, it is the name of a built-in AutoLISP function
declare the variables locally (imperatively the *error* function)
use getkword and initget to let the user choose an option.
(defun c:df (/ *error* oom option startpt ptx pty nextpt) ; local variables
;; *error* local redefinition
(defun *error* (msg)
(if (/= msg "Function cancelled")
(princ (strcat "\nError: " msg))
)
(if oom
(setvar "osmode" oom)
)
(princ)
)
(setq oom (getvar "osmode")) ;store current state
(initget 1 "Horizontal Vertical")
(setq option (getkword "\nChoose an option [Horizontal/Vertical]: "))
(if (setq startpt (getpoint "\nChoose Start Point : "))
(progn
(setq ptx (+ (car startpt) 10))
(setq pty (+ (cadr startpt) 10))
(setvar "osmode" 2) ; change state state
(while (setq nextpt (getpoint "'Pick Mid: ")) ;make selection
(if (= option "Horizontal")
(command "_dimlinear" startpt nextpt "H" (list 0 pty))
(command "_dimlinear" startpt nextpt "V" (list ptx 0))
)
(setq ptx (+ 5 ptx))
(setq pty (+ 5 pty))
)
(setvar "osmode" oom) ;revert state back to original.

I've been using AutoLISP/CAD for a while and now I want to add a label with my name to all the open files. I've managed to iterate over all the open files, but the text command only runs in the first file. I thought it was too quick for CAD to work properly, so I added delays but it didn't work. I've checked in all the open files and the variables are shared and synced. By the way, the text is added once per open file, but only in the first one.
Here is my code:
(defun c:labeling()
(vl-load-com)
(setq docs (vla-get-documents (vlax-get-acad-object)))
(setq top (vla-get-count docs))
(setq p1 (list 10 -10))
(setq p2 (list 95 -15))
(setq p3 (list 12 -14))
(setq c 0)
(vl-propagate 'docs)
(vl-propagate 'top)
(vl-propagate 'p1)
(vl-propagate 'p2)
(vl-propagate 'p3)
(vl-propagate 'c)
(while (< c top)
(vla-activate (vla-item docs c))
(command "_rectang" p1 p2)
(command "delay" 500)
(command "_text" p3 "3" 0 "My name - year" "" nil)
;(print c)
(setq c (+ c 1))
(vl-propagate 'c)
(command "delay" 1000)
)
)
It's a bit complicated to explain in such short time I have but:
Each drawig has his own "namespace" probably it's wrong word, but nevermind.
When You run command it runs only in active drawing, but when You change active drawing You lost active lisp routine.
So it's not enought to activate drawing.
Better way is to draw by manipulate model object. for example like this:
(defun c:labeling()
(vl-load-com)
(setq docs (vla-get-documents (vlax-get-acad-object)))
(setq top (vla-get-count docs))
(setq p1 (list 10 -10))
(setq p2 (list 95 -15))
(setq p3 (list 12 -14))
(setq c 0)
(vlax-for ThisDoc docs
(setq Space (vlax-get-property ThisDoc 'ModelSpace ) )
(Rectangle Space p1 p2 )
(setq txt (vlax-invoke-method Space 'AddText "My name - year" (vlax-3d-point p3 ) 3 ))
(setq c (+ c 1))
)
)
(defun Rectangle ( Space P1 P2 / lpts pts poly )
(setq lpts (append p1 (list 0 ) (list (car p1 ) (cadr p2 ) 0 ) p2 (list 0 ) (list (car P2) (cadr p1) 0 ) ) )
(setq pts (L2v lpts vlax-vbDouble ) )
(setq poly(vlax-invoke-method Space 'AddPolyline pts ) )
(vlax-put-property poly 'Closed :vlax-true )

(setq iCount (1+ iCount))
)

)
Here is the Code;

(setq Tcntr (+ Tcntr 1))
)
)
)
(setq TNumF Ttvm)

I want to get the Total area for all Region and Solids in Block (Tobjs) into variable TNumF, if it matches the condition,
it give an error: bad argument value: AutoCAD command: #
please help
Thanks in advance
It's because % is entity as vla-object, but command needs entity, so try this code:
(command "_.AREA" "_O" (vlax-vla-object->ename % ))
I've got a working batch-file that runs a script on a bunch of drawings.
The script is supposed to run a lisp-function but that function appears to only run after the main function has ran.
since I don't know much about lisps, I'll try to give the information I have.

One of the other functions is AR_LIST, which is the one I need to run on each file the batch-file opens, in a script.

the script only needs to run this command, close the drawing, and don't save.
so I tried (test.scr)
(ar_list)
quit
n
but that gives me the error:
Command: (ar_list)
bad argument type: stringp nil
I think the ar_list needs something from the defun c:areas , but I don't know what. The ar_list works after entering areas in the command bar.
So I also tried
areas
(ar_list)
quit
n
, but that opened the areas dialog box, does not close it, blocking the loop.
Also, when I cancel the dialog box, the ar_list works, but it again opens the areas dialog box. I think the code repeats itself in the script.
Any help would be very welcome. I received related help on here
stringp nil give us sugestion that some variable which should be text string in fact is nil. Probably because it reads value from dialog control (which is unavaliable while dialog is not active).
there is few places which may cause such problem:
we don't know what happes in ge_dir ge_dwg ge_puntlist vindpos ar_write
ar_write Maybe want to write something to dialog?
variable dwgnaam is used as string but never initialized in this function, (maybe somewhere else it is?)
(setq depname (cdr (cadadr (assoc -3 (entget (ssname sel num)'("COSBI")))))) (if (not (wcmatch depname "*island*")) if selected entity not contains XData "cosbi", it can be problem, but if I'm not wrong, there is other error message.
