one!3d – Solutions that go hand in hand.

one!3d is a network of scientists, engineers, architects, artists, programmers and designers.

Complexity is not the problem. It’s the opposite: it represents solutions, which, just a few years ago, seemed to be impossible to implement.

Complexity is only difficult when it requires methods that aren’t completely in line with one another. It is a challenge of the advancing digitalisation that it enables highly specialized applications, but that there is often a lack of smooth exchange between them.

To gain control of the “trickery of the method”, str.ucture brought one!3d to life – a think tank, which aims at enabling interdisciplinary work.

During demanding real estate and infrastructure projects, solutions from the area of design, engineering and construction are closely interconnected with one another. The collaboration often is not. one!3d is the expert network that wants to change this.

We believe that unrestricted transparency and the unrestricted exchange of information pave the road to success for all parties involved. Therefore, one! 3d is only secondarily a think tank. First and foremost, one!3d is an attitude.


Kiwi!3D – Design and analysis in a seamless workflow.


Complex construction projects benefit if all actors involved exchange information early on. Many decisions are already made in the draft phase, – for example in terms of supporting structure – which have far-reaching consequences for the whole building process.


Design meets Engineering.

To date, the feedback options between architect-sided Computer Aided Design and engineer-sided Computer Aided Engineering were very poor. NURBS-based description procedures are hardly compatible with ones based on Finite Element Methods – at least the translation workload is high, contains errors and only works from CAD to CAE and not the other way round.

Kiwi!3D now makes it possible to integrate design and analysis in the same process – which comes with great advantages:

• The data of the design model can be used directly for simulation applications.
• The simulation results enable a reliable evaluation of the draft.
• The results generate optimisation scenarios, which flow seamlessly back into the design environment and modify the draft accordingly.


Powerful Tool in a Powerful Working Environment.

Kiwi!3D is a plug-in that brings together two widespread modelling systems in one working environment: Rhinoceros/Grashopper on the CAD-side and Carat++ on the CAE-side.

The plug-in takes over the following tasks in the integrated process:
• Assembly of the analysis model from the CAD geometry
• Data transfer to the external calculation engine (Carat ++)
• Reimport of the analysis results into the CAD software and visualisation


Faster, Better, United.

The more demanding the construction tasks the more intensive the interlacing of draft and construction. Creativity and efficiency are no longer competitors. They support one another in order to achieve the best results in the most aesthetic and economical manner. Kiwi!3D offers the necessary collaborative platform for this purpose. The working environment delivers a model that centrally manages all data – practically a type of Pre-BIM. Draft and construction work hand in hand to achieve a more accelerated and efficient planning.

Thus, Kiwi! 3D is establishing a construction phase for cooperative collaboration that so far has not been taken into account in classical Building Information Modeling – without which, however, a true 360 ° view of building projects remains incomplete.
