Hi, The short answer is yes, QGIS can do that sort of stuff, but I'd use a different workflow which I think is easier.
If you have a spatially enabled database (Postgis, Spatialite, MySQL, MariaDB, etc), I'd do it there. Spatialite is probably the best to start with if you have not used one before. Have a table with a point column for your points, add a polygon column for your 600ft circle, another for your 1200ft, etc, Populate the columns by buffering the point with the appropriate radius (1/2 your circle diameter). The quadrants can be generated several ways -eg: ST_Project() will extend a line in a specified direction from a specified point, then clip those lines to each of the circles - and you have the quadrants. Connect to the DB with QGIS, open the table and plot each of the columns as a separate QGIS map layer. Set the symbology of each circle to "no fill" or to mostly transparent. Make sure these layers are above your background/context layers. Happy to help if you contact me off list.

(600 feet, 1200 feet, 1800 feet, 2400 feet and 3000 feet) I will need to be able to draw these circles without covering the aerial view or topographical view features under them as well as draw lines disecting these circles into 4 quardrans. Is this software able to perform these tasks?? Any help is greatly appreciated, Thanks Michael J.
