For background, I'm used to AutoCAD, Solidworks and Inventor, but am looking to use QCad at home because it can run under Linux and looks like it will do everything I need for personal use. Waste not, want not.
It seems like a lasting relationship between entities isn't made with snaps like it would be in the above mentioned programs. For example, if I snapped the center of a circle to an intersection between two lines, then moved one line (and hence the intersection), the circle would remain unchanged. Is this the case or am I missing something?
(Note that this is in now way a pointed question.)
