Thanks for your description of some sophisticated, top down design
methods. 
But, to echo Graham's concern, how do these methods preserve relation****ps

to the parts they are based on?

This was the one, judging by the name and reputation, that I thought had
the 
best chance of preserving a relation to the parent part. But, I haven't
used 
it and I'm not sure why its use seems to be so confined to molds and 
castings. Any insights as to why it isn't more widely used!?!
