<div dir="ltr">I have been unable to use the Rectangles Ovals Digitizing plugin to add
buildings shaped like a circle. I have tried doing this in versions
2.8.5, 2.1.3 and 2.1.2 of QGIS. Even though the icons of this plugin are
activated, when I click on the icon that should make a circle, it instead
makes an equilateral triangle that has the apex of the triangle oriented
horizontally to the right. And the Advanced Editing toolbar does not
seem to have an option to make a circle.<br></div>
