From CAD to real-time 3D: how product design teams validate ideas faster

CAD to real-time 3D: validate product designs faster with Overtools

Design reviews are critical steps in every product development process. They align teams, foster ideas, and de‑risk key concepts to improve quality and market fit.

Yet in many industrial organizations, design validation still relies on static renders, PDFs, and fragmented feedback loops. At a time when products are becoming more complex and timelines tighter, these workflows no longer scale.

With real‑time 3D and Omniverse, iteration cycles become dramatically shorter, accelerating decisions, reducing costs, and strengthening alignment across teams. By extending CAD into a shared, interactive review environment, product design teams can move faster, from concept to decision, without compromising quality.

Design reviews shouldn’t slow innovation

In many industrial design teams, reviews remain a major bottleneck.

Complex CAD data used for engineering purposes is exported into static renders. PDFs circulate by email, meetings are difficult to schedule, feedback arrives asynchronously, and key issues often surface when changes are already costly.

Meanwhile:

·         product variants multiply

·         customers are getting used to more personalization and tailored offerings

·         cross-disciplinary teams grow

·         expectations for visual quality increase

At LS GROUP, we see a clear shift: teams that move from static validation to real-time 3D and on-demand photorealistic rendering at various steps of the product lifecycle drastically shorten review iteration time and reach alignment earlier.  Expanding the use of digital mockups and leveraging it into collaborative, real-time validation workflow.

Why traditional design validation no longer works

When validation relies on offline renders and sequential approval loops, several issues emerge:

·         Design problems are discovered late

·         Iterations increase due to fragmented feedback

·         Teams work in silos, using different tools and workflows across CAD, simulation, ergonomics, and design, which makes it difficult to create a shared view of the product and collaborate efficiently during reviews.

As a result, decisions are postponed, not because options are unclear, but because they are hard to visualize, compare, and discuss together as a whole with cross-disciplinary teams. Most teams are currently working in silos, making decisions on their very own perimeter with complex interaction with other stakeholders: CAD engineers, designers, ergonomics, simulation, color & materials, ... Workflows and tools are different.

This is why more industrial players are adopting standardized asset representation and real-time 3D workflows for:

·         product design reviews

·         factory and process planning

·         training and immersive validation

This digital transformation and adoption of new standards allow teams to explore, question, and validate ideas collaboratively, much earlier in the design process.

Digital transformation

Digital transformation, standardization (Open USD, GLTF), Real-time 3D, interactive experiences

are not just about speed. It fundamentally changes how teams collaborate and make decisions.

With a real-time 3D environment, design reviews become:

• Interactive

Geometry, materials, lighting, and variants can be explored live, without re-exporting data.

• Cross-disciplinary

Engineering, design, quality, and even marketing work from the same source of truth, reducing misinterpretation.

• Decision-ready

Photorealistic visuals help stakeholders validate options confidently, without waiting for offline render cycles.

Behind the scenes, CAD data is prepared for real-time use through tessellation, cleanup, and optimization, steps that can now be streamlined and partially automated.

Why OpenUSD and Omniverse are key enablers

This shift is made possible through the adoption of a set of new technical foundations.

OpenUSD provides a robust, non-destructive scene format that supports:

·         Unified and standardized way of describing a scene

·         composition

·         variants

·         scalable collaboration

NVIDIA Omniverse builds on renowed GPU with extensive rendering capability and adds:

·         Nucleus for shared assets and collaboration

·         Ability to import CAD and connect to most DCC tools

·         High-performance RTX real-time rendering

·         Cohesive SDKs to create custom tools

Together, it forms a flexible backbone for digital transformation company-wide, unlocking modern, collaborative design validation workflows.

Overtools: real-time design reviews made practical

This is where Overtools comes in.

Developed by LS GROUP using Omniverse ecosystem, Overtools is a software product designed for industrial design teams who need clarity, speed, and control over design reviews.

It helps teams to:

·         Import and organize CAD assets into structured scenes

·         Create, manage, and compare variants effortlessly

·         Generate high-fidelity, photoreal visuals in no time

·         Conduct expert design reviews, in desktop or immersive (XR) modes

On our website, we share how Overtools is already used in industrial contexts, including a Stellantis experience focused on building 3D master models and running project reviews with a minimal number of clicks.

A typical workflow: from CAD to decision

A real-time design review session typically follows these steps:

1.     Import CAD data CAD is imported into OpenUSD using Omniverse Connections.

2.     Define variants Materials, trims, options, and configurations are organized as variants.

3.     Review live in Overtools Teams explore the product in real time using:

a.     lighting and environments

b.     measurements and exploded views

c.     annotations and side-by-side comparisons

4.     Capture decisions Photoreal snapshots or videos are generated and shared with management and cross-teams.

5.     Optional XR review Scale, ergonomics, and perception can be validated before committing.

Instead of weeks of back-and-forth, teams often reach alignment in a single review session.

Business impact for product design teams

Across projects, the benefits are consistent:

·         Earlier detection of design issues, reducing late-stage fixes

·         Shorter review cycles, enabled by shared scenes and instant visuals

·         Stronger alignment between engineering, design, and marketing

Because validated assets are reusable, they can also feed downstream uses such as:

·         digital showrooms

·         XR experiences

·         visual marketing and e-commerce

All without recreating content.

Frequently asked questions

What does “CAD to real-time” actually involve?

CAD data is tessellated, cleaned, and optimized, then assembled into OpenUSD scenes that can be reviewed live in Omniverse and Overtools.

Do all reviewers need high-end workstations?

Not necessarily. Omniverse supports centralized data and optimized or streamed workflows. The right setup depends on deployment models and review needs.

Can these assets be reused for marketing and communication?

Yes. Assets validated in Overtools can be reused for digital showrooms and visual marketing experiences, reducing duplication and production time.
