Jay Thomas supplied Thick Leaders with Text (Tip #2184) that he whipped up for a colleague on the fly and later decided to share with all of us. This function draws a leader with an arrow using a thick polyline (one with a width not equal to zero). It draws the arrowhead and line as a single polyline object and places text at the end of the leader. Load the LISP code and then type PLL to get started. The first time into the program you are asked to verify the default settings (obtained from the AutoCAD system variables). This function does not create an associated dimension object, meaning that edits to the output are performed using regular AutoCAD commands should you want to relocate the leader or change the text. This is a nice set of functions, and very useful when marking up a drawing. Thick polyline leaders are hard to miss, especially if you do them in a different color.
