Lisp erases snap settings- Please help!

Hi guys,

I have a beautifull lisp that I found that creates lines at specific devisions from the user , my snap settings are usually on ( I select all my object snap so I can pick every point as my cusor change ) but when I want to use my lisp again I need to select all the object snap again.

How can I keep my setting so it will not erase them?

LINE_DIV.lsp

You could add an command to fix the osnap again. I wouldn't know what changes the settings, but you can restore it

(command "-osnap" "endpoint,midpoint,center,node,quadrant,tangent")

Add and/or delete the snaps you want, and place this line of code somewhere (or at the end) of your lisp.

Hi OMEGA-ThundeR,

Thank you for responding but it didn't solve my problem. I added your code to last of my lisp and it seems to erase the setting again.

maybe something is missing in your code, please check.

I don't know how to check or write lisps.

Thank you.

Hmz.. strange... i shall test the code myself... brb

Ok, i guess it has something to do with the 'osmode' variable and that will probably fix (or is) the problem but i don't know how to.

But after adding the line of code after;

(setvar 'osmode 16384)

(somewhere in the first few lines of code in the lisp) i kinda got it to fix the snappoints again.

so it would become something like this:

           (setvar 'osmode 16384)
(command "-osnap" "endpoint,midpoint,center,node,quadrant,tangent")
          (setq spaces  (test spaces1 ())

It's an dirty fix i guess. Someone else might give a better sollution.

Thank you OMEGA-ThundeR,

I found a solution.

here is the fixed code.

(defun c:somefunc  (/ f curlayer curosmode ent exit a b spaces spaces1 testlst vlaobj1 vlaobj2 x y z)
(defun *error* (msg)
(setvar 'osmode curosmode)
(princ msg)
(princ)
);defun error

Hi guys,

 

I have a beautifull lisp that I found that creates lines at specific devisions from the user , my snap settings are usually on ( I select all my object snap so I can pick every point as my cusor change ) but when I want to use my lisp again I need to select all the object snap again.

I modified the start of your code removing "EXIT" in defun as you shouldn't redefine autolisp functions and it wasn't used in your code anyway. I added an *error* function and localized it by adding *error* to the defun to make sure the variables were reset while not affecting *error* for any other lisp. Then moved setting curosmode & curlayer to the top outside the while loop so it would only be set once.

Try replacing the start of your code with:

(defun c:somefunc  (/ *error* f curlayer curosmode ent a b spaces spaces1 testlst vlaobj1 vlaobj2 x y z)

 (defun *error* (msg)
              (setvar 'osmode curosmode)
              (setvar 'clayer curlayer)
              (princ msg)
              (princ)
 );defun error

 (setq curosmode (getvar 'osmode)
              curlayer  (getvar 'clayer)
 )
 (while (setq vlaObj1   (vlax-ename->vla-object (setq ent (car (entsel))))
              vlaObj2   (vlax-ename->vla-object (car (entsel)))
              spaces1   (getreal "\nEnter number of spaces: "))
   (cond ((or (minusp spaces1) (< spaces1 1)) "Spaces should be greater than 1")
