I would like to have a lisp routine that will automatically load every time I open a drawing even when in the same session of Autocad. The command that I want it to do is to set the variable "LAYEREVAL" set to "1" when I open a drawing. How do I go about this?
Actually, the file the OP should use (if they have write-access) is ACADDOC.lsp - See this tutorial instead.
** Note - Only use Startup Suite if you do not have write-access to ACADDOC.lsp
ACADDOC.lsp is a user defined file, meaning that AutoCAD does not come with this file, but you can create one if it does not already exist, and AutoCAD will automagically load this file if found anywhere within your Support File Search Paths (SFSP). This code will do what you have requested economically:
