I was wondering what the best method would be to display or turn on the visibility controls of a pline around text or an attribute if it is not null? I have an external app filling in attribute on drawings, but I want a certain black that is off in the drawing to be turned on if the attribute value is not null. I can't seem to find a method yet. Any suggestions or ideas.
And I know that I can use lisp or scripts for this but I want to perform this actions without those methods is possible. Any suggestions would be appreciated.
