Layer Emergency!

Morning everyone,

I'm having an emergency this morning with layers in a dwg. There are three layers that are frozen and won't unthaw. I'm not sure where to begin or what to do. The layers that need to be unthawed are:

W6_x_15#

MC18_x_42.7#

C12_x_20.7#

The underscores are spaces, there is a similar layer name without spaces that is ok. Your help is appreciated.

LAYER PROBLEM.dwg

I just opened the drawing and all the layers are thawed.

Here is the drawing renamed with the layers thawed. I did nothing but open it.

THAWED-LAYER PROBLEM.dwg

Maybe just close the drawing and reboot your system and try again.

Thanks Buzzard - by the time I got this posted a co-worker got it fixed. What we tried was this:

One Cadder tried renaming the layer on his machine and that didn't work, the other cadder tried straight command line input to unthaw and that didn't work. What finally worked for us was a LISP rountine (at the bottom of this post).

Now here's what is weird - after the fix I tried the renaming of the layer and that worked for me on my machine. All of our machines are the same - software and hardware. How strange this one was. Hope the info will help someone else.

BTW we run ACAD 2009.

LISP:

(defun C:LAA (); LAYER ALL (ON & THAWED) (command ".LAYER" "THAW" "*" "ON" "*" "")

(PRIN1))

Whats even stranger is the drawing you posted with the problem was OK. I guess its just one of those days.

Glad it you got it straightened out.

This may be a problem caused by using the "#" character in the layer name. Although it is not one of the documented characters to not use, it is suggested to not use any symbols except ;

. period or dot

- dash or hyphen

_ underscore

~ tilde

+ plus sign

As indicated, after you used the lisp posted, then renamed the layers, everything was fine.

Yep - this is proof that I'm in the Twilight Zone today!

The # symbol was in the posted drawing and worked fine. If it were a bad symbol AutoCAD would not allow you to enter it in the first place. Go figure.

We didn't rename the layers after the lisp run on the original file. I just happened to have a test copy of the file open and renamed them without running the lisp routine which worked on my machine, but not on the other machines. Weird huh?!
