Solid Edge

World-class modelling and rendering made RotoSub do the switch to Solid Edge

RotoSub designs silent fans. In April 2018 this innovative technology company based in Linköping, Sweden, decided to change its CAD system to Solid Edge, a CAD solution from Siemens PLM Software.

“We needed a powerful modelling tool that could handle the complex, asymmetric and curved geometry of our fan blades. Solid Edge manages this perfectly, providing better results than the former system,” says RotoSub CEO Lars Strömbäck.

Uses of RotoSub noise reduction fan technology range from home appliances such as refrigerator fans to large ventilation fans used in industry.

RotoSub recently took an order from NASA requesting silent fans that would reduce noise around the astronauts aboard the International Space Station. This project envisages using RotoSub technology in NASA deep space missions where prolonged exposure to noise has negatively impacted the wellbeing of astronauts.

“We use Solid Edge for all new projects,” says Lars Strömbäck. “Model creation for the NASA order is at least 40 per cent faster using this new CAD system, and our customers also benefit from the savings of time and expense that Solid Edge provides.”

Modelling capacity was crucial for converting to Solid Edge, and the transition went smoothly
Lars Strömbäck and his team discovered the ease of modelling in Solid Edge through a customer contact, and were sufficiently impressed to convert from their former CAD-system.

The transition to Solid Edge was easier than anticipated. New functions can be learned with the aid of an extensive series of short Solid Edge instruction videos available both through Siemens PLM Software channels and a broad community of keen Solid Edge users who post their own explanatory videos online.

KeyShot rendering: a positive surprise in Solid Edge

One unexpected and welcome benefit of Solid Edge for Lars Strömbäck was KeyShot. By importing models in KeyShot, RotoSub can quickly and simply create precise 3D renderings and animations of a product, enabling RotoSub to show photorealistic rendering of products to the customer.

“Customers often believe that we have already manufactured the product after viewing a KeyShot rendering, because the rendering is so realistic. This gives the customer a feeling of confidence in the outcome that helps us to promote our product,” Lars Strömbäck explains.

Synchronous technology: the next step

Even before shifting to Solid Edge, RotoSub had heard good things about Synchronous technology, the unique technology available in Solid Edge.

“Despite hearing only favourable reports of Synchronous technology, we choose not to deploy it from the start, but benefited from other great technologies such as modelling and excellent rendering,” Lars Strömbäck reports.

Deploying Synchronous will bring many changes in work processes for RotoSub, but Lars Strömbäck can already envisage the benefit:

"Synchronous technology will be very helpful when refining files with models from our customers working in other CAD systems, and we plan to start using this technology soon.”


Lars Strömbäck, CEO, RotoSub:

“We are very pleased with our decision to switch to Solid Edge, and we are now looking forward to deploying Synchronous for even more benefits.”
