Object snap, insertion, turns itself on

[WPerciful]

I'm not sure why but my object snap turns itself on. This happens when new drawings load, between commands and when I go from drawing to drawing. It's the insertion snap that turns on.

 

Also the grid snap turns itself off when new drawings load, between commands and when I go from drawing to drawing.

 

I'm running Autocad 2014.

Sounds like you have some startup code running or you're running a lisp routine that is changing the OSMODE sysvar.

 

AutoCAD 2016 includes a feature that can alert you when things like this change.

In earlier versions, you need some 3rd party code like this: http://cadpanacea.com/wp/?p=971 to help you isolate what is doing this for you.

The only lisp runing is mine.

 (while (setq tdata (tblnext tbname (not tdata)))
  (setq tblist (append tblist (list (dxf 2 tdata))))
 )
)
(if (member "PID_Border" (tnlist "block"))
(progn 
 (setvar "osmode" 0)
 (setvar "snapmode" 1)
 (princ "\nObject snap has been turned off. ")
 (princ "\nGrid snap has been turned on. ")
)
)

You can autoload lisps in many different ways so it still points to a loaded lisp, like SS:STARTUP, was your Autocad install done by you or by someone else Cad manager ? Type LSP and look for something by name that does not look like a Autocad function.
