Line Smoothing

[Bghost12]

Good morning everyone,

I hope this is a simple question with a simple answer.  I want to have Line Smoothing turned off permanently.  I get into a drawing, turn it off, work in the drawing and eventually close AutoCAD.  Once I reopen 2015, the line smoothing is turned back on again.  Is there a variable or something I can do keep it off?  Thanks.

Line Smoothing, is it new for 2015 or is it VIEWRES ?

Are you using plain AutoCAD 2015 or a vertical?
Are you loading a startup or an external profile when you start 2015?
I thought the new line smoothing variable was a system wide variable in 2015.

The LINESMOOTHING sysvar is saved in the registry according to the documentation, so either that is wrong or you have some startup code turning it back on.

LINESMOOTHING (System Variable)

Specifies whether anti-aliasing is turned on or off. Currently, the system variable applies to 2D objects in 2D wireframe visual styles.

Type:	Integer
Saved in:	Registry
Initial value:	ON
OFF	Specifies anti-aliasing is off.
ON	Specifies anti-aliasing is on.
Note: You can also use 0 (OFF) and 1 (ON) to set LINESMOOTHING system variable.

Hello

Yes LINESMOOTHING is a NEW 2015 variable !

And it can be enable/disable from : OPTIONS / System / Graphic Performance

Please look at the JPG ...

Yes I know how to disable the linesmoothing.  What I'm saying is that if I close and then reopen AutoCAD, the linesmoothing is turned back on. I have to disable it everytime I open 2015.

So open 2015 and before you do anything else, type in DBMOD and enter.

What does it return?

Anything other than 0 and you have some startup code doing something.

Now start running the "U" command until you cannot undo anymore. Did that undo the LINESMOOTHING sysvar change perhaps?

(BTW: I would test it myself, but I don't have 2015 in front of me at the moment)

I typed in DBMOD and it did return 0.

I started R2015, opened a blank drawing file. Turned off the variable LINESMOOTHING. Closed R2015.
I then opened the file I just saved/created, typed LINESMOOTHING and it's still OFF.
I closed R2015 again, and opened another file to check the variable. Still OFF.

Win7 64bit here, plain AutoCAD 2015.

I was able to verify that is does not change for me, but in the 2015 Beta Release Candidate version.

So I supposed it's possible that they changed the behavior of LINESMOOTHING in between that and the shipping version (EDIT: or NOT, based on Dean's reply just above)

You could also create (or append if you already have) an ACADDOC.LSP file and add the following to it:

(setvar "linesmoothing" 0)

Make sure this file exists somewhere in your support file search path.

If you do this, and it works for you, try the DBMOD command again after a fresh startup. It should still be 0.
