I posted this as a thread some time back but because it is often difficult to find a thread again I thought I'd pin it as an FAQ.
This is a link to the Fisher ISA specification sheet program:
The blurb says:
"Designed for engineers, Fisher® Specification Manager software offers a powerful set of tools for producing an ISA specification sheet faster, improving noise prediction calculations and exporting dimensional data for Fisher and Baumann™control valves. You'll find it easy to learn and use. Fisher Specification Manager software helps take the worry out of control valve specification."
If the link goes dead then google for "Fisher Specification Manager". (This is one of the advantages of their being insufficient experienced sales engineers; the rise of the selection and specification programs which can be used by pretty well anyone. It is an approach not without its pitfalls but useful none the less.)
