A complete ecosystem to manage your space
From digital modelling to crowd simulation: every tool is designed to plan, present and sell complex spaces.
What is
What are Viewito and Expi4D
Viewito is the cloud 3D design studio: design and furnish complex spaces (halls, stands, rooms, properties) directly in the browser, with over 2,600 components and photorealistic AI rendering in seconds. Expi4D is the pre-designed interactive 3D viewer to present and sell these spaces at fairs, events, hotels and large real estate.
01
Digital twin & advanced modelling
Digital twin & advanced modelling
We build complete, detailed digital representations of your spaces, accessible at high fidelity from any browser and device.
Every model is built from real surveys and data, then optimised to be explored smoothly on desktop, tablet and smartphone. Users navigate the space first-hand, follow customisable guided tours and switch with one click from immersive 3D views to 2D floor plans and technical CAD projections — always keeping context.
- Highly-detailed 3D modelling
- Immersive navigation and guided tours
- Instant switching between 3D, 2D and CAD
- CAD/BIM data and real-survey import
- Models optimised for performance on every device
02
Editing & layout management
Editing & layout management
Edit objects, furnishings, stands and signage in real time. Create unlimited layouts and share them with clients and teams.
Organisers edit stands, furnishings and signage without depending on anyone: move objects, duplicate layouts and save unlimited versions to share with the team or with clients. The crowd simulator assesses the impact of every layout on people flow before anything is built.
- Real-time editing of objects, furnishings, stands
- Unlimited fixed and custom layouts
- Crowd simulator
- Multiple shareable layouts and versions
- Measurement and scale-accurate planning tools
03
Events & exhibitor management
Events & exhibitor management
Manage exhibitors, spaces and editing privileges, with programmes, interactive calendars and granular public/private sharing.
From the interactive map, exhibitors find their stand, manage their own content and update information independently. Organisers assign granular editing privileges, publish programmes and calendars with day/hour search, and integrate videos, presentations, galleries and downloadable documents. A single environment to coordinate every aspect of the event.
- Exhibitor management with editing privileges
- Interactive calendar with day/hour search
- Multimedia content integration
- Exhibitor profiles and dedicated content
- Integrated B2B networking and matchmaking
04
Analytics, feedback & optimisation
Analytics, feedback & optimisation
Surveys, heatmaps and interaction statistics show you how visitors move, to optimise future events and spaces.
Heatmaps and interaction statistics show where visitors concentrate, which areas draw the most interest and how flows move. The collected data feeds customisable reports and drives decisions for future events and spaces, increasing the value and return of every edition.
- Surveys and interaction heatmaps
- Customisable statistics and reports
- Visitor-flow monitoring
- Surveys and in-app feedback collection
- Exportable, customisable reports
05
Accessibility & hybrid events
Accessibility & hybrid events
Accessible paths, audio descriptions and dedicated tours. Full support for hybrid physical and virtual events on one platform.
Accessible paths, audio descriptions and dedicated tours make the space usable by everyone, including people with visual or mobility disabilities. The single platform for hybrid events engages physical and remote attendees at the same time, multiplying reach without giving up the immersive experience.
