I have a site and want to draw an indicative line in a 5km buffer around the centre of the site. So I want to draw a circle with a radius of 5km. I have a tool for drawing circles and ellipses and rectangles squares and spirals.



None of these let me state the centre point and the radius.

As commented by @Roy, you could make a point in layer and then buffer it into a new layer.

With mmqgis plugin you can convert your geometry type to centroids :



Plugins > mmqgis > modify > convert geometry type



And then just create buffers on shapes (through Vector > Geoprocessing tools) and precise the desired radius.



You got it

    While developing a standalone qgis application, I shot help from QGIS Python Plugins Repository many times and it is very helpful. For drawing different geometries like Rectangle, Circle, Oval and Ellipse etc. this plugin is of great help.
