AutoCAD LT

[#1]

Thanks all for the help.

I have all my layer management LISP routines converted over to LT.  Now on to the others!

I also had to give you two kudos for those two post. Great solution and follow up explanation.

This one is even better, a true toggle.  The only thing is that you have to make sure the var "layon-off" (or whatever you're using)  is created/existing with a value of 1 (specifies that said layers are on) before running it. 

^C^C$M=$(if,$(=,$(getenv,layon-off),0),setenv;layon-off;1;_-Layer;ON;m*;;,setenv;layon-off;0;_-Layer;OFF;m*;;)^Z

 HTH!

There are many on-off needs for AutoCAD users, these tips can be modified with a little imagination to do so much in LT.

I'm sure we all have our favorites, think about it during a typical day of CAD and the flood gates will open.

Remember though, SETENV accesses the Windows Registry to add these user "environment variables": some registry cleaners like to remove them. AFAIK limited Windows user accounts are not affected in creating them, but I've never tested it.
