How can change a geometry from relative to absolute

[Lindsey]

I have created a shape by combining 2 others - let's say it's a square
within circle. What I want to achieve is, when I scale the shape, the
outer circle scales, but the inner square says the same size but
retains it's relative position.
I've looked at the shape sheet and can see that the geometry of the
inner shape is based on things like "Height*0.7759", so I can see I
need to change these values to absolutes rather than relatives.
Is there an easy way to do this?
I know I could do it manually, but in reality the inner shape I have
is not a square but a complex shape so has lots of points that would
need converting.

Depends how you combined the shapes. The prefered solution is to group the
shapes.

When you group two shapes, you create a new shape that contains information
about the group. The component shapes are changed to refer to the group
shape for size and positioning.

Within the geometry section, the Height refers to the Height of the
individual shape within the group. If you look at the first section, you
will notice that the Height and Width reference the Height, Width, PinX and
Piny of the group shape that contains the shapes that were grouped. Change
the Height and Width to be independant of the group shape. For centering,
the PinX and PinY should remain dependant on te group shape.

the shape was made by using shape>operation>union. This means that
they are a single shape so as far as i can make out the group thing
doesnt really help
