[Uml-user] deleting default lines between classes

[Catherine Moroney]

Hi,

I'm drawing a class diagram with lots of "contains" relationships
(class B contains an object of Class A) and my diagram is getting
very cluttered up with lines.  Is there some way to turn off the
default drawing of all these lines so I can draw my own subset
of them later.  I've tried double-clicking on and then deleting
all the unwanted lines, but when I double-click on a class
object, all the lines come back.

Another question tangentially related to lines: how come
umbrello draws the "B contains A" lines by default, but
does not draw the "B is a child of A" lines?  And, why
doesn't the class settings contain a field where you
can enter the parent class (if any).  Just curious -
the tool seems to do everything else but not this.
