MITCalc is a multi-language set of mechanical, industrial and technical calculations for the day-to-day routines. It will reliably, precisely, and most of all quickly guide customer through the design of components, the solution of a technical problem, or a calculation of an engineering point without any significant need for expert knowledge. MITCalc contains both design and check calculations of many common tasks, such as: spur and bevel gear, belt and chain gear, bearings, beam, pins, buckling, shaft, springs, bolt connection, shaft connection, tolerance analysis, tolerances and many others. There are also many material, comparison, and decision tables, including a Système for the administration of resolved tasks. The calculations support both Imperial and Metric units and are processed according to ANSI, ISO, DIN, BS, CSN and Japanese standards.It is an open Système designed in Microsoft Excel which allows not only easy user-defined modifications and user extensions without any Programmation skills, but also mutual interconnection of the calculations, which is unique in the development of tailor-made complex calculations. The sophisticated interaction with many 2D CAD systems (AutoCAD, AutoCAD LT, IntelliCAD, Ashlar Graphite, TurboCAD) allows the relevant drawing to be developed in a few seconds (3D CAD systems, SolidWorks, Solid Edge, Autodesk Inventor are supported in MITCalc 3D). OEM licensing of selected calculations or the complete product is available as well.
