With Geometry Shapes complement you can draw a circle / oval just with a center 
point and setting radius (x) and radius (y)

Dear Madeline,

If you want to start with a point layer representing the center of the
circle, then you can use the Shape Tools plugin to create either a geodesic
ellipse or donut about the point. If you use the donut, just set the inner
radius to 0 and the outer radius to 37.5 meters. You can also pull the
radius you want to use from the attribute table. In QGIS there are multiple
ways to accomplish what you want to do so just pick what works easiest for
you.

Re: [Qgis-user] Create circle with diameter in QGIS

[Christine]

Dear Madeline,
you may start with a point layer : the point(s) as the mid point(s) of your
circle(s).
Then you can draw a buffer of a certain distance with the buffer tool
(geoprocessing tools) around your point(s). In case of a buffer for points
the distance is the same as the radius of the circle you are searching for. 

Attention: the segments parameter controls the number of line segments to
use in oder to approximate a circle when creating rounded offsets. More
segments mean a closer approximation. Be aware that a shapefile cannot save
a true circle by nature but only an approximation to a circle with straight
segments. 

With the multi-ring buffer tool you might create more than one buffer at a
time around your point(s), so you could get as many rings (circles) around
your point(s) as you like. Certainly you have to determine the distance
between the circles you want to get. The output of the buffer tools have
automatically a polygon geometry. 

Regards, Christine

Re: [Qgis-user] Create circle with diameter in QGIS

[Andreas Neumann]

Ah - and don't forget that you need to finish the circle with the 
right-mouse button!


So the steps are (more or less):

- enable editing

- enable advanced digitizing tools (the button with square and ruler)

- enable the circle tool (e.g. "Add Circle by a Center Point and Another 
Point" tool)


- click in the canvas to set the circle center

- press "d" for distance and enter your radius (e.g. 5)

- press right mouse button to finish the circle

Hope this helps,

Andreas

The shortcut "d" (distance) is your friend. When this mode is activated 
you can enter distances (like your radius) with the keyboard and QGIS 
will constrain to these values.


You need to invest a bit of time to understand all the construction 
modes, but once you get it, it is quite powerful.

I would like to create a circle whose diameter is 75 metres. I am 
using QGIS version 3.16.3-Hannover.


My procedure so far has been like this:
1. create a new shapefile layer -> geometry type: polygon
2. in edit mode of this layer: add circle with centre and another 
point
--> How can I change the radius/diameter of the circle afterwards or 
is there another possibility to create a circle with diameter
