Topic: Isoplane?

[PHX cadie]

I've had to do a couple of iso's so far, and I would like to have a button set up to toggle back and forth, like we did at the previous employer.  Without knowing the command I'm constantly stuck going back and forth to Tools>Drafting settings>Snap and Grid>checking/clearing the isometric snap button. I've tried isoplane, but that had no effect on my crosshairs, (no effect at all that I saw)

What would the command in the command line that I can use to turn the iso snap on with a single entry? 

Thanks!

SNAPSTYL is the system variable for isoplane (0 - normal, 1-isometric), you could customize
a button with "SNAPSTYL 1 " for iso on & "0" for normal.

Awesome! Thanks!

I would have never found that digging around in the iso* section w/o luck.

Yes I could do flyout with two buttons, so I'm happy. I'm just wondering now if there is a way to set snapstyl opposite of its current setting? A toggle on/off method. Didn't see much in help file and/or my lack of skill in programming. Looked at the tframes button as an example and the command is ^C^Ctframes, wonder how that toggles on or off, (opposite of the current setting) 

Anyway Thanks!

I muck around with lisp (learning) so if no one laughs,
I wrote this to toggle iso on/off, just drop it into your startup suite and
assign a button with "tframes1"

Code: [Select]

(defun c:tframes1 (/ oldvar)
(setq oldvar (getvar "snapstyl"))
(if (= oldvar 1) (setvar "snapstyl" 0) (setvar "snapstyl" 1))
)
(princ)
hope this helps

Good Paul.

Here's another idea to tuck away ..

because :-
(abs (1- 1)) ;< = 0

(abs (1- 0)) ;< = 1


Therefore : ..

(setvar "snapstyl" (abs (1- (getvar "snapstyl"))))

Can you not right click the snap button on the bottom of the screen and select iso?

(setvar "snapstyl" (abs (1- (getvar "snapstyl"))))

BOOLE?

Not yet I think ... let him digest that first .. The Lisp Boole isn't for newbies .. or people without excellent memories.

Just a thought.

Here's a macro and the lisp to go with it.
It serves as a great toggle feature for a button

^C^C(if (not C:sst)(load "sst"));sst;




(defun c:sst ( / )
    (setq csnap (getvar "snapstyl"))
    (if (= csnap 0) (setvar "snapstyl" 1) (setvar "snapstyl" 0))
)

Using same format someone showed for toggling tilemode, a little less code than Kerry's;

Code: [Select]

(setvar "snapstyl" (- 1 (getvar "snapstyl")))

[Kerry]

Yes Carl that is simpler ..


Now to satisfy Randy and use Boole ...

The logical operator used with boole for XOR <exclusive OR> is 6,

resulting in  ;

(boole 6 1 1)  ; <<= 0
(boole 6 1 0)  ; <<= 1

therefore you could use :-

(setvar "snapstyl" (boole 6 1 (getvar "snapstyl")))


ADDED:
the logical operator XOR  returns true if only one of the input bits is true.

Thanks Kerry for the lesson, some digesting needed now.
everyone can stop chuckling at my code

Who's chuckling ? It satisfies the first condition : It WORKS !

Dude, can't speak for anyone else, but in my book any code that works is good code.
