Lisp : Wildcard Search

A wildcard character is a special character that represents one or more other characters. The most commonly used wildcard characters are the asterisk (*), which typically represents zero or more characters in a string of characters, and the question mark (?), which typically represents any one character. Wild card search is a great trick to maximize your search results in a drawing.  

So I have made a lisp named wildcard lisp that utilizes these search criteria’s to change properties or remove specific text or specific range or texts.
Wildcard lisp is similar to quick select option in AutoCAD this lisp helps more convenient and simple and multiple search can be added with comma “,” e.g.: (A*, C*, 5*, etc.). The below table helps how to use character’s in wildcard search.

It is very useful to remove some specific range of levels from existing survey levels drawings. Normally it will take lot of man hours with this lisp we can save more than 60% of man hours.
