I've recently started at a new company and as the new guy I'm hesitant to suggest something so pricey considering we would probably use a fraction of its capability. Oh, this package would need to be able to handle graphics, like screen shots of a FEA model that you paste in the report.
In case you're wondering, I used Mathcad for many years. I was using ver. 11 at my old job. Now I work at a place that uses Word to document their calcs. Those guys seems to be fine with it but using Word for math is like fingernails on a chalkboard to me.
