Season 3 [Fusion] Chapter 4: How to Solidify Organic Shapes Brought by Topology Optimization
T3Japan
Topology optimization autonomously derives a "minimal structure through which forces flow" and presents organic and beautiful shapes. However, the output mesh (STL/polygon) has a coarse surface, necessitating manual remodelling using traditional CAD. This task not only requires significant labor but also poses the problem of trace errors, which can compromise the mechanical performance that the optimized shape inherently possesses.
In response to this challenge, ThinkDesign offers a unique approach called "Direct Surface Fitting," which utilizes the mesh as a target. By adhering the underlying NURBS surface to the surface of the optimized mesh using the GSM (Global Shape Modeling) function, it can smooth out fine irregularities and instantly convert it into a high-quality NURBS surface (G2/G3 continuous).
This enables both data lightweighting and complete CAD geometrization to be achieved simultaneously. Furthermore, since manufacturing features such as bolt holes and draft angles can be added and integrated within the unified environment, it becomes easy to create high-precision solid models that merge the theoretically optimal shapes derived by computers with human manufacturing requirements.

Nice to meet you, I'm Takachan, working in sales (which is more like a pre-sales role) at ThinkDesign. Usually, I listen to clients' desires for "the kind of service they want to create" and bridge the gap to turn those into a "concrete blueprint" that engineers and designers can easily realize.
