I am pleased to hear that, I used to be involved in casting and patern making in a previous life... I recall complaints from customers who had supplied the patern and no drawing, when the cast part had no machining allowance, a time consuming if not too expensive mistake usually.
We always made sure that the new boy got to measure up something he had cut on the saw using the contraction rule (not expansion.. I forgot the name) watching him turn the rule round and over and getting a different result each time was priceless.:cheesy:
