When you draw a rectangle manually with line or polyline, or with lisp coding, you need to supply 5 points. Try it and count the points.

You are not drawing correct polyline if you omit to supply "Close" option after 4 picked points... Remember to do this as your new habit as when it comes to sharing your drawings, you may be the cause of incorrect drafter's job... Many of codes were provided accounting that your polylines are closed entities DXF code (70 . 1) for 2d polylines and if you don't stand by the rule of "C" option, some of the codes may fail to execute properly... Still there is CleanPoly.lsp on the site of Gile that can convert these wrong polylines to correct ones, but I strongly suggest that you use close option and to use it like learned by hard...

 

Attachment - Giles routines - original and the one I modified for multiple polylines...
