Need a lisp....... Lee Mac this ones for you

[Se7en]

I started to look at the code in v3 but i got so confused i had to stop. However, while i had the file open i noticed a lot of osnap checking and conditions and whatnot so i thought i would toss this out there to see if it could help.

 

If all you want is to ensure the osnaps are off when they are supposed to be then you can use boole 3 in a quick toggle procedure.

 

REMOVED: its wrong

 

 

 

HTH

Se7en,

 

I am trying to understand your code, but will the Boole expression not just output 0/1?

[Se7en]

yes BUT thats what you want (Your "flipping a bit").

 

brb...

[Lee Mac]

But surely you don't want to be setting OSMODE to 1...?

[Se7en]

Your not setting the osmode to 1. Did you try it? ... never mind. Here is a real quick explanation to its inner workings (A real quick "Flipping bits" lesson).

 

If my current osmode value was say 247 then this is how it would look in binary notation.

 

16384:   1 0 0 0 0 0 0 0 0 0 0 0 0 0 0
247:     0 0 0 0 0 0 0 1 1 1 1 0 1 1 1
        ^
        |
        +----- I'm "flipping" this bit in the current osmode value

 

Flipping the 16384 bit is like hitting .

 

Hows that sound? Cool huh? I'll find an article which will explain it better.

 

brb (be right back).

Yes, I tried it, and I could only get it to set OSMODE to 0 or 1... hence my queries..

 

I understand your logic and yes that is pretty cool

[Se7en]

*blink-blink* what do you mean you could only get it to set osmode to 1 or 0? Did you use the procedure like: (toggleOsnap 1) or (toggleOsnap 0)?

[Lee Mac]

Yes, I used it as you describe, and only get 1 or 0, as expected by the boole expression.

[Se7en]

Sorry, had a fire to put out here (and lunch).

 

Yeah, i screwed up. Im sorry.

 

Would this be better? Its not Boole 3...its more like Boole 2 or 7 depending but the same concept.

(defun toggleOsnap (value)
 ;; if `value' = 1 then turn osnaps off
 ;; if `value' = 0 then turn osnaps on
 ;;
 (setvar "OSMODE" (boole (+ 2 (* value 5)) (getvar "OSMODE") 16384))
 (princ)
)

Nice one Se7en, I like it.

Mike try this:

 

V1.3 : Added options to change line dimensions.

 

 

Thats perfect, but it only lets you change the vertical offset

[Lee Mac]

Thats perfect, but it only lets you change the vertical offset

 

Everything works fine for me...

[MikeP]

Everything works fine for me...

 

 

The drop down after change defaults only list exit and V. Should it list the other values as well? after I change the V, it goes back to "exit & V" If I click exit, it goes into point selection

[MikeP]

never mind, I just realized what i was missing, on the screen, the dropdown down not include the other values, but in the command line it does. All is well now

 

Thanks alot man

[Lee Mac]

I never use the "drop-down" so wasn't sure about that. But glad you got it sorted.
