This article introduces Tunny, Optuna's 3D CAD wrapper. We will start with an introduction of Rhinoceros, a 3D CAD software on which Tunny runs. Then, I will provide a brief overview of how I implemented Tunny. Finally, I will walk you through some design examples using Tunny, including crash safety design of a car front bumper in connection with CAE, and Human-in-the-loop optimization of vase shapes and architectural column placement.

In order to simulate a metamaterial structure efficiently, it is replaced by a uniform shell element.

We designed a folding hanger that can be mass-produced by plastic injection molding as a technology available today.

As an example of integrating multiple components using compliant mechanisms, we will introduce the design of a folding hanger.

We exhibited as a startup at the Automotive Engineering Exposition Nagoya and had a great time discussing with many visitors. We are grateful to all those who were interested in our technology and vision. In our exhibit, we presented design technologies and case studies of shock absorption, thermal, and vibration/stiffness. As we interacted with visitors, we saw the potential to solve important problems in the manufacturing industry. We look forward to your continued support and anticipation.

Karamba3d is a structural analysis plug-in that runs on top of 3D CAD Rhinoceros Grasshopper. Karamba3d is not a well-known commercial CAE like Ansys, so I am curious about its performance, However, as there is not much information on this, this article will check it on a simple model.

Our company develops various products utilizing shape processing, function calculation, and design technologies. In this article, we explain Implicit Function Modeling, one of the means of modeling geometry.

We will introduce how to implement and use your own shape representation classes on Grasshopper with code. This is a useful tool for a variety of applications, so please try it out.

We continue to build our in-house software environment to advance our unique structural design. The components of the software environment are diverse, but one of them is the freely extensible geometry processing-numerical analysis environment, and we are extensively using Rhinoceros, a 3D CAD system, and its plug-in, Grasshopper, in an extended manner. In this article, I hope to write mainly about the important but rarely mentioned aspects of developing and using Grasshopper plug-ins. As someone who got hooked on Rhino+Grasshopper as a student and has been doing this kind of work ever since, I hope I can help a lot of people get started.
