Default Global Linetype Scale Problem

[Anonymous]

My default global linetype scale seems to be 0.4 instead of 1. For instance, I opened a drawing and the global linetype scale showed 0.4. I opened the same drawing on all other colleagues' autocad and the global linetype scale showed 1. This problem has been occurred for the past two weeks. I'm not sure if I changed the setting by accident. Does anyone know how to solve it?

Since that's saved in the drawing file, any change you may have made in the setting in one drawing on your computer shouldn't affect the setting in any "global" sense, meaning applied to any other drawings than the one in which you change it.  I suspect you have something that's changing it upon the opening of every drawing, such as in an acaddoc.lsp file that your computer uses but not others'.  If that's the reason, it should be happening in every drawing you open -- is that the case?

Hi,

LTSCALE is saved in the drawing, so if opening the same drawing on two different workstations should show the same value for this variable.

If that is not the case then you do have some 3rd party addon or a vertical product that changes that variable automatically each time a file was opened.

That can also be a small line in the ACADDOC.LSP file if there is one in your environment (or maybe at your colleagues environment setting the value automatically to 1)

Hi,

My autocad only changes drawings that have global linetype scale of 1 to 0.4
automatically. For drawings that have global linetype scale other than 1,
they do not get affected. I'm not sure how to solve it. Is there an autocad
package I can download to overwrite existing files?

Thank you,

That sounds like a tool is active on your system.

First you have to look if something is loaded into AutoCAD that is not installed by AutoCAD itself.

To see if an application is installed it might help to show us 2 screenshots:

1. your complete application window, so we can see the complete menu area
2. start command _OPTIONS, activate tab "Files" and open the topmost item in the tree "Support File Search Path", then again create a screenshot from that and upload this screenshot too

Also type in that lisp statement including the parentheses:

(findfile "ACADDOC.LSP")

...does AutoCAD find such a file (you'll see a filepath in that case) or does it report "nil" after you started that statement?

If you have AutoCAD 2016 or later, you can make use of the System Variable monitor to monitor LTSCALE and/or other related sysvars.

Also, right after you open the drawing on your machine, and it finishes initializing, run the "U" command over and over until there is nothing to Undo. Check your linetype scale then.

I've attached photos of my application window and support file search path. My (findfile "ACADDOC.LSP") reports nil. I ran the "U" command after I opened the drawing, and the global linetype scale went back to the correct setting.

Acaddoc.lsp is not the only startup file that is executed when a drawing is opened.

The fact that your "U" commands undo the change makes it clear that something is doing it.

I don't know what PWGSCAtlantic is, but it is a candidate too. This is a file that is loading at startup.

Hi,

I'm with @rkmcswain

These items don't belong to standard AutoCAD, I guess that's a good first position to search (and hopfully find) the reason for your LTSCALE automatically resetting.

Try to get in contact with that application developer.
