sometimes when drawing a rectangle with the rectangle comand or doing one with  a poliline, the vertices of the rectangle, if I apply a certain width, donˇt remain totally closed.  Sometimes the endings, due to the line's width, remain with a little failure. i.e. as the width is made since the axis of the line, as the endings of the rectangle meet, they don't fully close. Sometimes they do and sometimes they don't. Can anyone explain it to me ???

 

Thx a lot
