Innovations & extensions

Improved 3D assistant
for intuitive modeling

Graphical wizards in MDESIGN offer a quick and easy way to create designs without having to perform calculations. In MDESIGN mechanical and MDESIGN bolt, the "Bolt" modules have been expanded to include this input option.

New AI-powered assistant "
" for MDESIGN bolt

The new AI assistant in MDESIGN bolt helps you select the optimal utilization factor according to VDI 2230. It helps you determine when your own specifications are appropriate—and when different values make sense. This makes specifying the tightening torque even safer and more efficient.

Transparent assembly processes at the click of a mouse in accordance with VDI 2230 Sheet 3

An automatically generated assembly sheet with calculation values in accordance with VDI 2230 Sheet 3 (draft) summarizes all the important parameters for a safe, traceable assembly process. This provides you with clear and standard-compliant documentation of your bolted joints at the touch of a button.

New screw types for more practical applications

Numerous requirements have now led to an even wider range of applications for screw calculation.
calculation. Additional bolt types can now be calculated and verified with MDESIGN bolt (e.g. new bolts, 12-point socket head cap bolt, plug screw and hook bolts as well as tie rods).

Additional "O-ring" module

With the new MDESIGN "O-ring" module in the MDSIGN mechanical range, you can calculate geometries, installation spaces and groove filling levels in accordance with ISO 3601-2 - simply, precisely and optimally tailored to your application.

Strong calculation of "Face Spline"

With the new MDESIGN module "Face Spline", the geometry, local tooth root stress and strength verification of splines can be determined quickly and precisely - for Hirth, Couvic-Coupling and cyclo-palloid splines with central and decentralized bolting.

Practice-oriented expansion:
New safety elements

The screw module now features extended databases with new locking elements such as Spring washers, locking edge disc, wedge locking washers and NSK washers are now available. In addition, the manufacturer data has been updated and expanded to include Teckentrup and Heico - for even more practical and standard-compliant calculations.

Progress often begins
with a step backwards

Finding the best solution with variants
a major benefit of MDESIGN. In addition to the parametric analysis, it is now possible to switch between individual steps forwards and backwards. This allows situational alternatives to be assessed quickly.

aiven - your smart assistant

With the new chatbot "aiven", you receive direct support with questions about calculation, operation and technical backgrounds. Whether you need quick help in your day-to-day work or in-depth explanations - aiven thinks along with you, explains things clearly and makes getting started with MDESIGN even easier.

More clarity, more flexibility: MDESIGNdoc is here

The previous MDESIGN PDF is being replaced by the new MDESIGN doc, which offers a modern and more flexible documentation basis. One new feature in particular is the integrated comment
function, with which the inputs and outputs of a calculation project can be supplemented directly in the document and explained in a comprehensible manner.

Focus on optimized usability

User-defined column visibility in database tables, individually customizable selection dialogs and interactive 3D graphics in the basic modules ensure intuitive and user-defined handling of the MDESIGN interface, even with large amounts of data.
