This video demos a technique to simulate
Table Lookups. At a stretch we could think of this as a simple
if, then, else construct.
This is Microstation's DDD at the limits of my knowledge, and it's fun too! BUT is very very useful aswell. Don't all Engineers love empirical formulae and Tables upon Tables of values when designing? Why not let Microstation look them up for you?
It is a combination of many behaviours and techniques described already, nothing new, just putting them together in a different way.
