There's a rule which says : min number of hits = 3*(number of hits to define a feature)
So 9 for a plane or circle, 12 for a sphere, 15 for a cylinder, 18 for a cone.
This rule is applied only for location and size, not for the form.
For the depht, I usually set it to zero, because I don't use CAD, it helps me to avoid some crashes on closed holes...
