I have used this excellent program for decades, indeed built a successful business using it. For me it is the ability to type in your equations using only secretarial skills, and then set your goals sculpting away at the various inputs until you achieve a perfect balanced result. I have combined product stress, materials, production costs, capacity etc all in one model providing my customer with instant answers. Brilliant program never beaten.
