Map AutoLISP values to the title block
You can vector to the title block system variable values or values extracted by
AutoLISP programs. For example, let's say that your system's environment
variable "USERNAME" contains a value that must show up on the drawing
title block. You set up your default.wdt file to map the AutoCAD Electrical
"LINE12" value to attribute "DWGBY" on your standard title block. Now you
want to automatically have LINE12 point at the USERNAME environment
variable so that, during title block update, the USERNAME value goes to LINE12
which, in turn, sends it on to the "DWGBY" attribute on the title block. Encode
the AutoLISP (getenv " ") function into the LINE12 value for your current
project description data.
Now when you run the Title Block update, make sure that LINE12 is selected.
During the update AutoCAD Electrical evaluates the expression (getenv
"USERNAME"), retrieves the environment value, and writes that value out to
