WiDim dimensioning software

Dimensioning of building elements: Quick and intuitive with WiDim

Functional, modern and intuitive to use: our new WiDim software allows you to dimension building elements for all your construction projects in an extremely convenient way. Only a few entries are required and you will receive all the information relevant to your construction project in no time at all.

As a specialist in building services engineering, our aim is to help you develop your project and provide you with high-quality products in the areas of fire protection, noise protection, air distribution and building control systems.

Our dimensioning software makes it easier than ever to optimise all the key data for a product. For example, you can dimension a ventilation system in no time at all. Working with the software is intuitive and guides you through the process step by step.

You can download the current version of the programme free of charge using the form below. After registering in the form below, you will receive a link to the download (currently only available in German).

The dimensioning of building elements: Advantages of the software

If you decide to work with WiDim, you can conveniently collect all important data in one project in your software. This includes, among other things

  • operating point data
  • product details and physical features
  • 3D visualisations of the products
  • the right accessories
  • current revision documents
  • the installation type and installation variant
  • the connection options of the selected building element
  • and much more

After dimensioning your building elements, you can easily output your finished project in various formats. Thanks to the clear arrangement of the information, you always have everything in view.

Additional features of the WiDim

The software also comes with even more features that make planning Wildeboer building elements much easier in your planning process:

  • a GAEB interface - i.e. a convenient way to exchange variant-related tender texts;

  • interfaces based on VDI3805 - i.e. the option of exchanging data from products to your CAD and calculation software.

These interfaces help to integrate the product into an end-to-end planning process. As a result, it is in turn possible to transfer the product to all common CAD and calculation software and thus obtain the CAD data in a simplified or detailed view and integrate the calculation data and other product information into the CAD and calculation software, allowing product-specific data sheets and tender texts as well as BIM data to be collected for upcoming projects and output or transferred at any time.

More information

In addition to our dimensioning software, we also provide an MSI installation file. This is intended to assist system administrators in making the program available to other users so that they can use it without special permissions. During installation, select a folder path where the user has write permission. This means that installation and subsequent updates can usually be performed without administrator rights.

The .Net Framework version ≥ 8.0 is required for installation.

At WiDim, we place great importance on continuous optimisation. For this reason, all identified errors have been corrected and necessary changes have been made in the new software versions. The release notes for the individual versions can be found here.

 

The following adjustments have been made in WiDim version 2025.208.1201:

 

General

  • Editorial changes
    Revisions have been made to some tender and long texts
  • Database update
    The databases have been updated with the latest information. (Including simplified selection of perforated sheet metal covers)
  • Selection of accessory components revised
    It is now even easier to select accessory components for products. (For example: selection of SKE-V silencers for square volume flow controllers)
  • Introduction of .Net8
    The new version now uses the .Net8 framework.

Fire protection and smoke extraction

  • Protective grilles available in RAL colours.
    Protective grilles for fire protection and smoke extraction dampers are now available in various RAL colours.

Sound insulation

  • SKB silencers, SB baffles removed from data set:
    The SKB silencers and SB baffles have been removed from the data set and are therefore no longer available in WiDim.
  • Tightness class C for SKE-V silencers
    Tightness class C is now available for SKE-V silencers (silencers for volume flow controllers).

Bug fixes

  • Several bug fixes
    Several minor bugs have been fixed to further improve the stability and functionality of WiDim.

WiDim can be called up directly from C.A.T.S.. Certain design criteria, such as room sizes, widths and heights of the products, can already be transferred to WiDim in C.A.T.S.. The component dimensioned in WiDim can then be drawn in C.A.T.S. via the interface. In addition to the rough component dimensions, the pressure losses and sound power levels at the design operating point and other product information are also available in C.A.T.S..

WiDim can be called up directly from RUKON. The component dimensioned here can then be transferred to RUKON using our unique VDI3805 databases. In addition to the geometries in simplified and detailed visualisation, the formulas for calculating the operating points, application limits and order data are also available in RUKON. This allows the products to react automatically to changes in the sewer network.

The designed products can be transferred directly to the LINEAR CAD browser and from there to LINEAR CAD (Revit and AutoCAD) via a direct interface. Geometries are available in simplified and detailed representations. In addition, all components have dynamic calculation data (formulae for calculating pressure losses and sound power levels). Pressure losses and sound power levels of the individual components react actively to changes in the duct network in your LINEAR CAD. This means that you can access the changing performance data of the individual operating points at any time.

WiDim can be called up directly from Trimble Nova. The building element dimensioned here can then be drawn directly into Trimble Nova via the interface. In addition to the geometries in simplified and detailed visualisation, the pressure losses at the design operating point and other product information are available in Trimble Nova.
