Tekla Structures 2021 hardware recommendations
Operating system requirements
Tekla Structures 2021 runs on the following operating systems:
64-bit Windows 10
64-bit Windows 8.1
Other operating systems are not supported.
Tekla Structures can be used with applicationpart of Tekla Structures functionality that is developed in order to extend the capability of Tekla Structures but that is not included in the Tekla Structures installation
and desktop virtualization. For more information, see Using Tekla Structures with application and desktop virtualization.
Recommended hardware for Tekla Structures workstations
The table below presents two different hardware configurations. The recommendations are mainly for desktop computers, but the same guidelines can also be applied when purchasing laptops.
These hardware recommendations are based on proven set-ups that are used in testing Tekla Structures. Other set-ups can be used if they are more optimal for your intended use. Various comparisons are available on the internet to evaluate other hardware against our recommended setups (e.g., here for GPUs and here for CPUs).
Before purchasing a large number of computers for your Tekla Structures users, test and verify the set-up first with one or two computers.
Tekla Structures does not support Itanium processors.

*Tekla Structures renderingprocess of making the model object faces visible
The rendered model object faces can be transparent or non-transparent
can use DirectX or OpenGL technology. The DirectX rendering mode is better optimized for modern graphics cards, and you should prioritize DirectX performance when deciding on a graphics card. We do not have resources to test all cards on the market, so we have chosen cards based on the NVIDIA graphics processor to be our test platform.
**A 3-button wheel mouse is required in all cases (to be able to finish some commands, and to zoom, pan, and rotate). Tekla Structures also supports 3D mice provided by 3Dconnexion to be used in tandem with a regular mouse to enhance zooming, panning and rotating. To use a 3D mouse, install the 3Dconnexion Device extension from Tekla Warehouse.
Graphics card configuration
Make sure that your graphics card is set up to use a high performance profile with Tekla Structures. You can check and assign the profile in the configuration tool provided by the graphics card manufacturer, or in Windows settings in recent Windows versions. This is especially important on laptop computers, which may be configured to emphasize power saving. Many systems default Tekla Structures to use a less powerful integrated graphics processor instead of the more powerful dedicated graphics card unless you change the setting.
In addition to the main Tekla Structures software, other software components also affect how the 3D models are drawn on your computer:
Your computer uses the standard drivers provided by the graphics card manufacturer also when drawing the 3D viewview that displays objects three-dimensionally
3D view is one of the default views.
in Tekla Structures. We recommend that you regulary check for updates to the graphics drivers from the manufacturer's website.
Before upgrading the drivers on a large number of computers, test the driver version first to make sure the update does not introduce problems in the 3D views in Tekla Structures.
Tekla Structures includes two alternative rendering engines: one based on OpenGL and one based on DirectX. Microsoft Windows includes support for both technologies.
Further tools to help you choose Tekla Structures workstation hardware
Join the discussion at Tekla Discussion Forum > Tekla Structures Forums > Hardware & operating system to exchange experiences with other users.
You can install TeklaMark from Tekla Warehouse to test the DirectX graphics performance of your setup and compare it to statistics from other users. For more information and the statistics, see the TeklaMark support article.
We also provide an application called Steelmark for testing and evaluating graphics cards for use with the Tekla Structures OpenGL rendering engine. Download it from Tekla Warehouse.
Requirements for connecting to Tekla Online services
Tekla Online services complement the Tekla software products with comprehensive learning and support resources, software installation package downloads, cloud-based sharing, and various add-on tools that enhance your use of the software.
To ensure full access, follow the requirements for connecting to Tekla Online services.
Tekla License Server
Tekla License Server is required for on-premises licensing.
We recommend that you upgrade to the latest available license server version. You can always install the license server on any computer that meets the Tekla Structures hardware recommendations.
If the license server is installed on a different computer, there are additional considerations for the hardware and operating system. See the separate Tekla License Server 2020 hardware recommendations.
If you use different versions of Tekla Structures, check the license server compatibility before you upgrade your license server.
Tekla Structures multi-user server
If you use the Tekla Structures multi-user server, we recommend that you always install the latest available version. At the time of writing, this is version 2.5.0.
For more information, see Tekla Structures multi-user server 2.5.0 hardware recommendations.
Tekla Structures uses the standard Windows printer drivers provided by the manufacturer of the printer. You can install the most recent driver from the manufacturer’s website.
Additional necessary software components
Tekla Structures needs the following redistributable packages that are automatically installed during the Tekla Structures software installation if they, or newer versions of the packages, do not exist on your computer:
- Microsoft .NET Framework 4.7.2
- Microsoft Visual C++ 2010 Redistributable (x64) 10.0.40219
- Microsoft Visual C++ 2010 Redistributable (x86) 10.0.40219
- Microsoft Visual C++ 2013 Redistributable (x64) 12.0.40649
- Microsoft Visual C++ 2013 Redistributable (x86) 12.0.40649
- Microsoft Visual C++ 2015 Redistributable (x64) 14.0.23026
- Microsoft Visual C++ 2015 Redistributable (x86) 14.0.23026
If your organization installs Tekla Structures centrally using .msi packages, it may be necessary to download the required .NET Framework and Microsoft Visual C++ Redistributable components from Microsoft’s web site and install them separately.
