PreCAD Mechanical Engineering Made Easy
Interactive Digital Prototyping Software

GrafiCalcĀ® is field-proven software that helps users to solve a wide range of mechanical engineering design challenges quickly and easily while making informed decisions in real time.

In GrafiCalc you simply point-and-click to bi-directionally associate geometry and calculations in the same worksheet to digitally prototype the functional intents of your design challenge. Then you can interactively substitute design parameters in the digital prototype to receive instantaneous engineering decision-support information leading to the optimal solution.

GrafiCalc can be used standalone and in conjunction with Microsoft Office and all popular CAD applications on any computer running any version of Windows.
