PreCAD Mechanical Engineering Made Easy
Design Better – First Time Right.


GrafiCalc® is groundbreaking software that helps users to solve a wide range of mechanical engineering design challenges with unprecedented ease, speed, and accuracy while making informed decisions in real time.

That is possible because GrafiCalc is driven by a game-changing graphical calculations engine that virtually eliminates tedious mathematical calculations and equations solving from the mechanical engineering design process.

In GrafiCalc you can simply point-and-click to associate parametric geometry and automated graphical calculations in the same worksheet to capture the functional intents of your design challenges. Then you can interactively substitute critical engineering parameters to ask and receive instantaneous design decision-support information and the optimal solution in minutes. Simply put, GrafiCalc enables users to work with geometry in the same way as spreadsheets work with numbers.

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