Tip 2219: Section Lines
Section Lines by Steve Schenck creates section lines defined by a quadrilateral. The four-sided figure is divided into four equal sections along each side with lines drawn that connect the edges. The result is a grid fashioned along the four sides. This tool is great for maps that have keystone shapes and other areas that can be defined using four linear edges. Load up the LISP code and type the command name QUADLINE to start the function. Next, you'll be asked to locate the four corner points defining the region. An option is presented to draw the section boundary before the automatic part takes over drawing the lines on different layers for easy identification and use. This approach to coding is very practical and straightforward. Nice job, Steve.
