PTC has announced the availability of the latest version of their engineering calculation solver, MathCAD Prime 3.0.

Touted as a "huge step forward from past Prime versions" this version of MathCAD is clearly a "productivity enhancer" with a host of new features in areas like:

Documentation Enhancements
Custom Functions
Global Definition Operator
Numeric Enhancements
Surface interpolation in contour plots
Usability Improvements

I look forward to each release of Prime because it brings in more and more functionality that I'm accustomed to with legacy MathCAD v15. With each matching feature introduced into Prime, conversions of older MathCAD files retain more of their original functionality.
