Title: validate layer names?
Post by: mkweaver on January 27, 2009, 08:58:17 AM

Isn't there a lisp function that will check a layer/block name for validity?  I've searched help, here on the swamp, and the autodesk newsgroups, but haven't found what I'm looking for.  Have I missed something?

Pointers appreciated.

Mike

Maybe something like this

Code: [Select]

      (if (tblsearch "layer" "layername")
(command "-layer" "s" "layername")
(command "-layer" "m" "layername" "c" "red" "layername" "")
      );;end of if

I'm not checking to see if the layer exists, I want to know if the layer name is valid - will I get an error if I try to create a layer with this name?

Thanks

While I envy your mastery, coding seems to have become more than a second language, heh MP?
