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: tooth, belt, and chain gear, beam, shaft, springs, bolt connection, shaft connection and many others.

There are also many material, comparison, and decision tables, including a system 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 system designed in Microsoft Excel which allows not only easy user-defined modifications and user extensions without any programming 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 (AutoCAD, AutoCAD LT, IntelliCAD, Ashlar Graphite, TurboCAD) and 3D (Autodesk Inventor, SolidWorks) CAD systems allows the relevant drawing to be developed or 3D models to be inserted in a few seconds. OEM licensing of selected calculations or the complete product is available as well. MITCalc installation packages are available at and after installation customer have 30 days to freely test the product.

2D CAD Systems

Most of the calculations allow direct output to major 2D CAD systems. Just choose your CAD system in the calculation and select the desired view (a projection type). A drawing is then saved directly in the CAD system with the correct scale and system of layers.

Supported CAD systems at this time: DXF file, AutoCAD (12-2019), AutoCAD LT (95-2019), IntelliCAD, Ashlar Graphite, TurboCAD. The design is fully open, customer can connect other CAD systems or define new drawing templates based on the calculated values.

3D CAD Systems

These are installed in the form of individually installed plug-ins containing relevant parametric models and an interface between Excel and the selected CAD system. An assembly may consist of not only individual components but also groups of components (sub- assemblies). For example, you can insert one complete solution of a belt gear at once, which is fully associative, and the dimensions of the inserted component (sub-assembly) will change automatically in case you make changes to the calculation parameters later. Supported CAD systems:

  • Autodesk Inventor
  • SolidWorks
  • Solid Edge
  • Pro/ENGINEER, Creo
  • User Interface

    Most of the calculations have a similar user interface whose main advantage is its top-to-bottom layout – every task flows logically from an assignment to the results. In other words, the structure of a calculation is like what you are already accustomed to when solving the same task with a calculator and sheet of paper. Other advantages of our solution are:

  • The “Expert Notes” system containing recommendations and tips for input and output values [1].
  • Support of standard and imperial units [2].
  • Recommended values – the calculation “knows” how to set (estimate) the right coefficients [3].
  • Any change of parameters immediately results in recalculation of the entire task (a table).
  • For most of the calculations, there is the “Automatic Design” mode available, which offers a set of solutions based on minimum input information and one parameter to optimize (e.g. weight, safety, dimensions) [4].
