[Qgis-user] Create circle with diameter in QGIS
Dear QGIS Team, 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: polygon2. 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 directly? Thank you very much and best regardsMadeline ___ Qgis-user mailing list Qgis-user@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user
Re: [Qgis-user] Create circle with diameter in QGIS
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
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.

Re: [Qgis-user] Create circle with diameter in QGIS
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 On 2021-03-12 14:08, Andreas Neumann wrote: Hi Madeline, You need to enable the "Advanced Digitizing mode/panel". See https://docs.qgis.org/3.16/en/docs/user_manual/working_with_vector/editing_geometry_attributes.html#the-advanced-digitizing-panel for details. 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.

Re: [Qgis-user] Create circle with diameter in QGIS
Hi Madeline, You need to enable the "Advanced Digitizing mode/panel". See https://docs.qgis.org/3.16/en/docs/user_manual/working_with_vector/editing_geometry_attributes.html#the-advanced-digitizing-panel for details. 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.
