Straight to the point What 3D can do for you

Visualization and simulation. Vidya can portray and expand reality in the computer, creating new opportunities and competitive advantages throughout the entire fashion process.

Model designs

Samples

Vidya is simply different. A digital prototype is and will remain a digital prototype. It must come as close to reality as possible and that requires changes. Processes and individual work preferences must be adjusted. The simulation is very often so good that you can “touch” the design with your eyes. The actual “feel” can then be checked on the physical prototype during a later design phase.

°° Idle and waiting times are eliminated – You can create variants (material, color, cut) instantly. Collaboration and release become much simpler.

Sales samples

°° Producing quality – Reality is digitally reproduced and expanded. 3D can have more sig-

nificance than a physical design, during fitting procedures on models with various standard sizes, for example, or thanks to functions like hiding cuts for better visibility.

Images in photo quality

°° Saving costs – Fewer physical prototypes reduce material consumption and workloads, while improved communication also provides relief.

3D with Reality Plus Vidya is a leading software program for 3D garment simulation. It enables the visualization and simulation of collections, with correct body dimension data, original CAD designs and real material parameters – and you can use this data throughout the entire fashion process.

That’s why Vidya is integrated with Cad.Assyst, iSize, PLM GoLive and with the Fashion Cloud GoLive.

Innovation signpost 3D right from the start

3D offers you all the possibilities of virtual product development. You can create and review many models, save on expensive prototypes and collaborate worldwide much more easily and all in parallel, assuming the simulation is as realistic as possible, with the correct pattern data, the right material parameters and – optimally – the body dimensions of your customers. This is where Vidya comes in.

Core questions: What 3D technology must achieve Question 1

Can you integrate 3D into your processes?

Yes, but. Companies develop their own processes. 3D integration is easy, but it does bring a few changes with it which have to be “run in�. Preconditions for seamless development with 3D are continuous data exchange with the neighboring CAD and PLM fashion systems, as well as the optimal integration of body sizetables. The management of the extensive 3D data must also be solved.

What can you do with Vidya? You can profit from digital processes.

3D creates a wealth of new data and Vidya manages it perfectly in the Cad.Assyst database. Vidya is also optimally networked with CAD and PLM, saving you manual data entry and a lot of effort throughout the entire process.

One Process: 3D data with added value You can use 3D with Vidya for the entire fashion process. Vidya data can be integrated straight into your processes, because Vidya is integrated with Cad.Assyst, PLM GoLive and iSize. This avoids media interruptions.

One Process:

Cad.Assyst + Vidya + PLM GoLive

6

Vidya can: digitally solve tasks in the fashion process

Selection of material: Check your colors and fabrics

Selection of designs: Create variants and manage pattern repeats

Initial and trade samples: Sizing & fitting control; grading; collection duplication

Pre-production preparation: Coordination with partners and in the company with the free Vidya Viewer

Reality Plus: Simulation in 3D can be even better than the real try-on: in hiding pattern pieces, for instance.

Question 2

Has a digital design the quality of a physical design?

Yes! The Albstadt-Sigmaringen University put this to the test and the result was that the real and the virtual try-ons are truly comparable. Many of the physical prototypes can be replaced, perhaps in some cases even all of them. The technical requirements for this are high quality simulation of human being, pattern and material, plus integration into a real 3D garment.

“The study has shown for the first time that the results of the real and the virtual try-on are really comparable. This clearly shows the great potential of virtual prototyping”, says Design Professor (FH) Barbara Puscher, Albstadt-Sigmaringen University.

What can you do with Vidya? You can display collections virtually.

80 % of all designs can already be visualized with Vidya – and this means huge savings.

Vidya can: digitally simulate real garments

Human beings: Vidya simulates persons with real data on the measurements, volume and motion behavior of their bodies.

Cut: Just like in real life, the simulated 3D garment consists of the CAD cuts sewn together.

More examples of Vidya simulations are at: www.vidya-software.com

Material: Vidya uses real material parameters that show the fabric’s natural stretch behavior and structure.

3D garment: Human being, cut and material interact perfectly for the simulation.

The same body measurements/sizetables are used in CAD and in the creation of avatars. Drape, stretchability and structure correspond to the natural movement behavior.

Question 3

Is 3D a financially viable proposition?

Yes. Economic viability is of course dependent on the individual objectives and the initial situation in your company. When it comes to cost savings though, the amortization of 3D technology is well worth considering. One obvious return on your investment is the savings on physical prototypes, not forgetting the far more important competitive advantages such as faster time-to-market by reducing idle and waiting times.

Vidya can: save you time Since many idle and waiting times are eradicated and coordination worksteps are much simpler, you can use Vidya to significantly reduce your time-to-market and get your collections into the stores fast. Initial projects showed that previous development timeframes could be slashed by up to 35 % – and that equates with several weeks.

Vidya can: save on physical prototypes Saving on physical prototypes is a key advantage that impacts on both time-to-market and costs. The business case is of course dependent on the specific situation in your company.

You can use the following example to assess your time and cost savings.

What can you do with Vidya? Increase productivity.

You have to wait for physical prototypes, but with Vidya drafts there is no waiting time for either model or material – and material costs are totally eliminated. So you can develop much faster and more cheaply, depending on the initial situation.

Opinions on 3D

Currently happening in the industry

How can we use 3D productively?

Excerpt from Case Study, fashion 04

BRAX uses 3D to save time and costs in collection development. The company launched its first season with 3D using a digital house model in Vidya. The main objectives were to speed up development and extract as much benefit as possible from the 3D data, from design to sales.

Even the pilot simulatio n showed that BRAX could significantly reduce the number of its physical prototypes and develop more variants at the same time. Thanks to simulation in Vidya, the hit ratio of drafts rose considerably. Fewer physical prototypes were needed, avoiding unnecessary delays. The use of correct body measurements that matched the company’s own sizetable was also crucial for BRAX. Even in the digital world, BRAX still works with a permanent house model, who is perfectly simulated.

“Vidya has the quality to achieve the competitive advantages that we want. We were very impressed by the imaging of our designs on our own house model.”“We expect to save even more time with 3D, achieving a quick response to the market trends that have become even more important for us as a vertical company.”“3D is not just “Plug and Play”.

Anyone who expects this cannot achieve any market success.”

Detlef Oesterreich, Head of IT, BRAX

We think in 3D Excerpt from the interview with Dr. Andreas Seidl, Managing Partner, Human Solutions/fashion 03

Virtual prototyping has three dimensions: time, cost and quality. In just a few years it will be as common as CAD is today.

“For companies with their own product development, virtual prototyping is the grand prize.”“We think in 3D, so we can work even better.”“You gain speed with every visualized piece. You build up a 3D library of your own collections, so to speak.”“To eliminate all the prototypes and samples would be utopian – but we can reduce their number dramatically.”“With 3D, development processes can be accelerated by 20 to 50 percent.”

Saving time with 3D Excerpt from an interview with Detlef Oesterreich, Head of IT, BRAX/fashion 04

BRAX is a well-established brand … and it’s growing. For some time now, the company has been working with Vidya in its womenswear blouses segment.

“With 3D in our processes, we can improve sizing & fitting and the punctuality of our deliveries even more.”“Our designs achieve a higher hit rate. We can risk more diversity and reduce the number of prototypes. Our house model is available in digital form, so we can forget about any more idle times in that respect. And we also use the simulation in Vidya for collaborating with our partners.”“If you want to work productively with 3D, you soon realize that using the real cut pieces, material parameters and body dimensions, plus management with PLM are all prerequisites.”

In concrete terms Planning, starting & using 3D

The advantages are obvious – but how can you achieve them? And what questions does this pose for team colleagues? The flow chart of our Assyst experts provides valuable recommendations and can be an invaluable aid in your own planning.

Tips for your project: 1. The design sets the tone! Products with lots of variants, such as pants (chinos, jeans), shirts (blouse, shirt, polo) and coats (sports) are ideal for the introduction. 2. Everyone’s needed – designers included! The sizetable for the basic pattern must be clarified and the right physical body has to be selected for the sizing & fitting philosophy. First time in 3D? Let Assyst show you what your model looks like in 3D! Quickly – but not too fast! Start with one model and a motivated team. Specify your timeframes clearly – too much time isn’t good either! 3. Learning time! What still doesn’t seem right? How are the experiences? How can the model be improved? What processes have been eliminated – and what should we add? Are there any new ideas for using 3D? 4. The moment of truth! How many prototypes have been saved? What do we miss from the old process? What process ballast have we finally jettisoned? Now you’re the experts! Experience has shown that values steadily improve the more practice a team gets – so repeat the success monitoring after four weeks, after the first collection and after the second collection!
