PTC Mathcad Prime 4.0 is a powerful software thats used by engineers and scientists in various disciplines, which is designed for analysis, solving, documentation and sharing of calculations and design intent. Mathcad is generally accepted as the first computer application to automatically compute and check consistency of engineering units such as the International System of Units (SI), throughout the entire set of calculations. Mathcad Prime is oriented around a worksheet, in which equations and expressions are created and manipulated in the same graphical format in which they are presented (WYSIWYG). Mathcad Prime 4 enables users to better connect calculations to other applications and processes including PTC Creo.
