6 xyz's, 5 strcats, 4 trans, 3 getpoints, 2 equations, and a partridge in a pear tree

ok, so there's not 5 strcats, but i thought the title was catchy.

 

so i've been making this NEW autolisp based off one i made last week of other people's code i cobbled together and personalized.

 

everything works EXCEPT the little equation i put in. here is the working code BEFORE i updated it:

 

(defun c:ptdif (/ p p1 p2 p3 x y z x1 y1 z1 x2 y2 z2 mdl pdiff ptcoord textloc cs_from cs_to)
(while ;start while

(setq cs_from 1)
(setq cs_to 0)

(setq p (getpoint "\nCHOOSE MODEL"))
(setq p2 (getpoint "\nCHOOSE SHOT"))
(setq textloc (getpoint p "\nPLACE TEXT"))

(setq p1 (trans p cs_from cs_to 0))
(setq p3 (trans p2 cs_from cs_to 0))

(setq x (rtos (car p1)))
(setq y (rtos (cadr p1)))
(setq z (rtos (caddr P1)))

(setq x2 (rtos (car p3)))
(setq y2 (rtos (cadr p3)))
(setq z2 (rtos (caddr p3)))

(setq ptcoord (strcat "Model:	X = "x"		Y = "y"		Z = " z))
(setq mdl (strcat "Sokkia:	X = "x2"		Y = "y"		Z = " z2))

(command p2)
(command "_leader" p textloc "" ptcoord mdl "")
(princ)
) ;end while
)

 

now that works nice and neat. The envelope i'm trying to push it just to add one more string into the text box with the differences between "x and x2" and the y's and the z's. i'll show you what i tried that didn't work. i think i was pretty close.

 

(defun c:ptdif ( / p p1 p2 p3 p4 x y z x1 y1 z1 x2 y2 z2 x3 y3 z3 mdl ptd ptcoord textloc cs_from cs_to)
(while 						;start while

(setq cs_from 1)				; these two keep it in world coords
(setq cs_to 0)

(setq p (getpoint "\nCHOOSE MODEL"))		; all my get points and prompts
(setq p2 (getpoint "\nCHOOSE SHOT"))
(setq textloc (getpoint p "\nPLACE TEXT"))

(setq p1 (trans p cs_from cs_to 0))		; the compliment to keeping it in world coords
(setq p3 (trans p2 cs_from cs_to 0))

(setq x (rtos (car p1)))			; breaks up x, y, and z from 1st getpoint
(setq y (rtos (cadr p1)))
(setq z (rtos (caddr P1)))

(setq x2 (rtos (car p3)))			; breaks up x, y, and z from 2nd getpoint
(setq y2 (rtos (cadr p3)))
(setq z2 (rtos (caddr p3)))

[b](setq x3 (- x x2))
(setq y3 (- y y2))
(setq z3 (- z z2))[/b]

(setq ptcoord (strcat "Model:	X = "x"		Y = "y"		Z = " z))
(setq mdl (strcat "Sokkia:	X = "x2"		Y = "y2"		Z = "z2))
[b](setq ptd (strcat x3 y3 z3))[/b]

(command p2)
(command "_leader" p textloc "" ptcoord mdl ptd "")
(princ)

) 						;end while
)

 

i've been googling my ass off and all my research says that my "equation" is correct, but i keep getting "error: bad argument type: numberp: "20.0212" "

 

now if i got "nil" back, i would revise things, but that tells me it stops at the equation, right?

 

sorry for my ignorance, i've just started doing this last week.

 

any help would be REALLY awesome. thanks for read this at least.

The reason for your error was because you had converted the coordinate values to strings (using rtos), and then attempted to subtract the two strings rather than the numerical values, resulting in a 'bad argument type: numberp: ' error, string the '-' function requires a numerical argument and you had passed it a string. For more information on error messages, see my troubleshooter here.

OHHH, so after i "rtos" them, it loses the definition of what they where.

 

Not quite; you are converting the coordinate values from the REAL data type to the STRing data type.

 

e.g.:

_$ (setq x 123.456)
123.456
_$ (type x)
REAL
_$ (setq x (rtos x))
"123.456000"
_$ (type x)
STR

 

thanks lee mac. You're the best.

 

Thank you.

LEE! i just wanted to say thanks again and wanted to show you something i added.

it totally works and i dont' need any help, but i did come across this:

 

http://www.cadtutor.net/forum/showthread.php?45355-lisp-to-round-up-numbers

 

and i didn't like that code. (pretentious, i know) Seemed like i didn't have enough control over what it actually rounded.

I know my code is really blocked and simple and redundant, but it's in a body that i can read with ease. i'm more of a "notepad" coder.

That visual lisp tutorial you have on your site is really great, but it kinda kicks into super advanced really fast.

 

TL;DR

thanks again, great website lee.

your "error message" page has become my favorite bookmark.

I'm sorry to hear that you found my tutorial to be too complex - I honestly tried to write it to be as clear and comprehensible as possible, however, it is incredibly difficult to gauge the technical level and read the tutorial from the perspective of a novice - all whilst striving to maintain the interest of the reader and avoiding informaton overload...

 

Though, I would strongly suggest that you use a code editor to write your code, rather than standard notepad. I would always recommend the Visual LISP IDE specifically for writing AutoLISP (AfraLISP has a few tutorials on the VLIDE if you found mine hard-going); but if you wanted to avoid using the VLIDE, there are a plethora of other free code editors available online - I personally use Notepad++ for all of my non-AutoLISP programming, as it is a great 'all-rounder'.

 

Other code editors include: UltraEdit / Eclipse / Vim / Emacs / MSVS ...

 

thanks again, great website lee.
