Bounded and Unbounded Datum Features

With regard to 'sized', primarily but I don't think limited to,
datum planes and axes; Pro/E is the first program I've used that
EVER treated the entities as 'bounded', e.g. finite in length or
area, except for graphical representation purposes and that threw
me for a loop or two in the past.


Wondering if there are any more details to be stumbled over and
as general curiosity questions:

Is there any documentation covering the subject?
Are there any config options controlling the behavior?


For instance ...


Bounded:
A datum point defined by two coplanar axes; the axes must
graphically intersect for the point to indicate the intersection.


A datum curve thru coplanar points; the points must be within
the graphical boundary of the plane in order to use the plane as
an 'on surface' reference.


Unbounded:
An axis need not graphically intersect a plane or surface to
place a point on it's intersection with plane or surface.


A plane need not graphically intersect another plane or a
surface to create an intersection axis or intersection curve.


Having experience with only two builds of Pro/E (short time WF,
the rest WF2) and never having seen any discussion re the topic I
wonder, too, if what I've described is a version / build specific
bug. Any explanations, thoughts?
