AutoCAD Visual LISP / AutoLISP :: Add Nil - Stop While Loop?
Oct 22, 2013
I am have trouble trying to figure a couple of things in the following code.
First - in the IF statement if "SD" is >= ask "Specify LAST strata number". How do I add nil?
Second - After I "Specify the LAST strata number", How do I stop the loop?
(defun C:22 () (setvar 'osmode 0) (or $S (setq $S 10)) (setq S (getdist (strcat "
Specify scale [Inches equal a Foot] <"(rtos $S 2 2)">: "))) (if (= S nil) (setq S $S)) (setq $S S) (or $BD (setq $BD 7)) (setq BD (getdist (strcat "
Specify boring depth in feet <"(rtos $BD 2 2)">: ")))

I am trying to put together a loop to enter a number greater than the previous number entered. Below is my mockup and I just cannot get it.
(defun c:22 () (while (setq d (getreal "
Specify diameter: ")) (setq $d d) (while (if (<= d $d) (progn (prompt "
Specify greater diameter.") (setq d (getreal "
Specify diameter: ")) ) ) ) (setq p1 (getpoint "
Specify point: ")) (command "CIRCLE" p1 d) ))

I have a little LISP I have been working on that creates a text object as a "label" for 2D ductwork our company does. It makes a field for the mlinescale as the duct width, combines with user input for duct depth, and prompts user for location to place the text. The routine is functional...however, I would like to tweak two things that I cannot figure out.
First, I would like the command to continue until the user escapes, similar to the "multiple" command in AutoCAD. I have tried adding a while loop to the majority of the routine..which works until the user escapes...then my error handler undoes everything.
Second, when asking for user input, is it possible to ask for user input without a default the first time, but thereafter remember the input as a default?
Below is the code in question...not including error handler, etc. :
(if (= ducttemp nil)(setq ducttemp 12))
(initget 6)
(setq ductdepth (getint (strcat "
Enter duct depth in inches <" (itoa ducttemp) ">, or Esc to end: ")))
(if (= ductdepth nil) (setq ductdepth ducttemp) (setq ducttemp ductdepth))

I am just a begineer for auto lisp. I wrote my first program, but got stuck, I am unable to get out from while loop if i Press "enter".
(defun c:arsh ()
(while
(setq p1 (getpoint "
pick point :"))
(setq l 1500)
(setvar "osmode" 0)
(initget 7)
(setq p2 (polar p1 (dtr 0) l))

I have a parent directory with x-amount of folders contained inside. I say X-amount because I would like to keep adding or deleting folders as time progresses. I want the folders contained within this parent directory do be read into a lisp variable and then be printed to the command prompt till every folder is displayed by name, then the loop may stop.

i am writing something that will draw consecutive lines with a rubberband to be used as a leader from a block's insertion point. this:
(WHILE
(SETQ LN (GETPOINT "
Select Next Point (ENTER to Finish) : "))
(COMMAND "LINE" (GETVAR "LASTPOINT") LN "")
)
works, but does not include the rubber band. i tried:
(WHILE
(SETQ LP (GETVAR "LASTPOINT"))
(SETQ LN (GETPOINT LP "
Select Next Point (ENTER to Finish) : "))
(COMMAND "LINE" LP LN "")
)
which includes the rubberband, but will not exit the loop. The last break source in VLIDE shows that
(GETPOINT LP "
Select Next Point (ENTER to Finish) : ") is casuing an error. Placing
(SETQ LP (GETVAR "LASTPOINT"))
outside the loop causes all lines to be drawn from the same point rather than the endpoint of the previous line.

I am looking for a way to extract (filter) all polylines, and loop a lisp based on the number that are found within a "W" selection window.I am frustrated getting "malformed list" or errors, even after defining "n" for repeat.The code I have so far looks like this:
(defun cWW (/ p1 p2 sspw myObj ss)
(setq p1 (getpoint "
Pick first corner: "))
(setq p2 (getcorner p1 "
Specify opposite corner: "))
(if
(setq sspw (ssget "W" p1 p2 '((0 . "*POLYLINE")))
[code].....
Without the (repeat () portion, it was working ok with selection window, however it only would run the commands for a single polyline. What needs to be done without overhauling the code? The lisp has worked on a drawing-wide basis, however needs to run on only on user-windowed polylines since there are other polylines within the drawing which are attached to layouts via viewports.

I am trying to create an mtext entity using entmake with different text height, text style and underlining. I have a subroutine that works fine. However - I would like to use different text height, text style and underline for the Title Text vs the following lines.
Here is the subroutine I already have -
(defun Create_MText (MT_PMS MT_Layout MT_Layer MT_Style MT_Justify MT_Point MT_Rotate MT_Size MT_Width MT_Title MT_Body / )
(setq FSC_MText
(list
(cons 0 "MTEXT")

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.

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?

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)

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.

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.

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?

I use Spell Check regularly and I always check the entire drawing. I would like to add to the Spell macro so that when I pick Spell from the toolbar it goes past the Check Spelling window and begins checking the entire drawing.
I believe I need to insert Alt S into my macro to select Start from the window to begin the check. Is there a character or series of characters that will represent Alt in a macro?

I upgraded from Autocad 2004 to 2012 recently and my lisp file doesnt work anymore.
what it's supposed to do is when looking at the layout tab that you want you can switch to the model space location of the same zoom as the layout tab without messing with the layout zoom.
(defun c:msp ()
(setq cm (getvar "cmdecho"))
(setvar "cmdecho" 0)
(command"view" "d" "tmp")
(setvar "tilemode" 0)
(command"pspace")
(princ "Click TWICE on desired VPORT: ")
(command "mspace" pause "view" "s" "tmp")(princ)
(setvar "tilemode" 1)
(command "view" "r" "tmp")
(setvar"cmdecho" cm)

Is there a command that is the opposite of starting an application to open up a file? Like:
(startapp "PlaySound.exe" (findfile "CuckooClock.wav"))
Instead of starting an application, how to shut all of its instances down. Let’s say I have iTunes and/or Internet Explorer w/ a few tabs open and I can close them down without getting to the application to terminate it the usual way.
Naturally,
(endapp "iTunes.exe") doesn’t work :-))

I have a drawing that has 2D pipeline (only x and y, z value =0) and 3 topo contour lines ( with x, y and z vaules). I need to divide the the 2D pipeline into say 2000 points and then get the corresponding z values from the topo contour lines. I think it can be done by interpolating between the z values for the two apparent intersection points of the 2D line and the contour lines, the x and y values will be the same for the points that falls between these two aparent intersections. Is there any lisp out there that can do that.

The following gives me the first folder string, with no back-slashes, that the drawing exists in.
(setq FirstFolder
((lambda (/ tmpDir tmpPos)
(substr
(setq tmpDir (getvar "dwgprefix"))
(+ 2 (setq tmpPos (vl-string-search "\" tmpDir)))
(- (vl-string-search "\" tmpDir (1+ tmpPos)) (1+ tmpPos))))))
Is there a way to find the name of the second folder?
Is there a way to find the name of the third folder?
The string length of the characters for each of the first, second, third (and so on) folders are different, which means I can't count character using the "substr" function.
