2space

Introduction

2Space is a cloud‑based collaborative platform that supports the design, visualization, and manipulation of three‑dimensional models across multiple disciplines. The system is engineered to facilitate real‑time interaction among architects, engineers, contractors, and clients, enabling stakeholders to review, edit, and annotate designs from any device with an Internet connection. By combining features from virtual reality, augmented reality, and traditional desktop applications, 2Space aims to streamline the product development cycle and reduce the time required to transition from concept to construction.

The core philosophy behind 2Space is the elimination of silos in the design process. Traditional workflows often involve the exchange of large files between separate CAD packages, leading to version control challenges and costly rework. 2Space addresses these issues by centralizing all model data within a single, persistent environment. The platform provides a persistent, versioned repository that automatically records changes, supports branching, and allows roll‑back to earlier states. This level of control is particularly valuable in construction information modelling (BIM) projects, where changes to a design can have cascading effects on cost, schedule, and safety.

In addition to its collaboration capabilities, 2Space offers a robust set of tools for data analytics, performance simulation, and automated reporting. By exposing design intent through a consistent set of metadata, the platform enables downstream processes - such as quantity take‑offs, cost estimation, and clash detection - to be performed with minimal manual intervention. As a result, organizations that adopt 2Space often report higher accuracy in project budgets, reduced lead times, and improved stakeholder satisfaction.

History and Development

Origins

The concept of 2Space emerged from a joint initiative between a small German startup specializing in 3D visualization and a multinational engineering firm seeking to improve its internal collaboration processes. In 2013, the founders identified a recurring bottleneck: the transfer of 3D models between desktop applications and cloud‑based services was time‑consuming and error‑prone. Their goal was to create a lightweight, web‑native environment that could host full‑fidelity models while remaining accessible to non‑technical users.

Early Prototypes

Initial prototypes were developed using WebGL for rendering and a lightweight Node.js server for data management. These early versions were tested internally within the engineering firm, focusing on basic viewing and annotation features. Feedback from the pilot highlighted the need for more advanced editing tools and tighter integration with existing BIM software such as Autodesk Revit and Bentley MicroStation.

Public Release

The first public beta of 2Space was released in 2016 under the name “2Space Explorer.” The beta version included real‑time view‑only access, basic annotation, and a simple API for uploading models. Despite its limited feature set, the platform quickly attracted interest from architectural firms looking to prototype collaborative workflows.

Enterprise Edition

In 2018, the company introduced 2Space Enterprise, a feature‑rich version designed for large organizations. Key additions included multi‑user editing, model versioning, permission management, and advanced simulation tools. 2Space Enterprise also introduced an SDK that allowed third‑party developers to build custom extensions using JavaScript and a set of RESTful endpoints.

Integration with Virtual and Augmented Reality

Recognizing the growing importance of immersive technologies, 2Space added support for VR headsets such as Oculus Rift and HTC Vive in 2020. The platform also released an AR module that enabled the overlay of BIM models onto physical construction sites via mobile devices. These additions were driven by the need for on‑site decision making and accelerated clash detection.

Recent Developments

In 2022, 2Space introduced a machine‑learning module that could automatically identify potential clashes and suggest mitigation strategies. The platform also expanded its data analytics capabilities, providing real‑time cost and schedule forecasts based on model changes. 2023 saw the launch of a cloud‑native data lake that allows for large‑scale aggregation of project data across an organization, facilitating enterprise‑wide reporting and benchmarking.

Architecture and Technology

System Overview

2Space operates on a multi‑tier architecture comprising the following components:

Client Layer: Web and mobile browsers that render models using WebGL, as well as VR/AR headsets supported by the WebXR API.
Application Server: Node.js‑based services that handle authentication, authorization, and API requests.
Data Store: A combination of PostgreSQL for relational data and Amazon S3 for object storage of large 3D model files.
Rendering Engine: A custom engine that translates proprietary 3D formats into the glTF standard for efficient streaming.
Analytics Service: A Python‑based microservice that runs simulation workloads and machine‑learning inference.
Integration Hub: An API gateway that provides connectors to external BIM tools, ERP systems, and project management platforms.

Model Format and Conversion

While 2Space accepts a wide variety of CAD file formats - including IFC, Revit, SketchUp, and DWG - the platform converts these into glTF for rendering. glTF’s binary format reduces bandwidth requirements and improves load times. For models that contain complex materials or nested assemblies, 2Space preserves hierarchy metadata and creates a lightweight index that enables efficient traversal during editing.

Real‑Time Collaboration

Real‑time collaboration is achieved through WebSocket connections that broadcast incremental changes to all connected clients. When a user modifies an element, the system propagates a delta that contains only the affected geometry and metadata. The receiving clients apply the delta locally, ensuring minimal lag even over high‑latency networks. Conflict resolution is handled through a “last writer wins” strategy augmented by lock‑management to prevent simultaneous edits on the same element.

Security and Compliance

Data security is enforced at multiple levels. All communication is encrypted using TLS 1.3. User identities are managed via OAuth 2.0, and role‑based access control ensures that only authorized personnel can view or edit sensitive parts of a model. The platform also complies with ISO/IEC 27001 and GDPR, providing audit logs and data residency options for multinational clients.

Extensibility

2Space exposes a comprehensive RESTful API that allows developers to create custom extensions. The API covers model operations, annotation management, user authentication, and analytics retrieval. SDKs in JavaScript and Python are available to simplify integration, and the platform supports custom plugins that can be installed on the server or client side.
