- As you may already noticed, LibreCAD do not support "Rectangle"
   entity, but just drawing rectangle using lines.
   This can be easily seen, when selecting "Draw" menu.
   i.e.: There is no "Draw"->"Rectangle",
   but just "Draw"->"Line"->"Rectangle".

- I see 2 alternatives to have something that behave more like
   a "Rectangle" entity:

        1) Draw a rectangle using a "Polyline" entity.

        2) Draw a rectangle using "Line" entity
           ("Draw"->"Line"->"Rectangle"); then
           create a "Block" using the 4 resulting lines.


Remark:
        - If you want "Rectangle" entity supported by LibreCAD,
          you can fill a feature request here:

Hope it help,
