Current Challenges of CAD Sharing in a Distributed Environment

The transition to remote work has exacerbated the pre-existing issues in CAD data management and sharing. Engineering departments now face technical and organizational obstacles that slow down design processes and limit the effectiveness of remote teams.

Limitations of Conventional Approaches

Traditional sharing methods such as email and FTP, although still widely used, present critical shortcomings in a distributed work context:

• Email attachments are limited in size and pose serious risks in terms of security and version control
• FTP transfers lack traceability and offer no guarantee regarding data usage after download
• Generic cloud solutions are not optimized for handling complex and voluminous CAD files
• Deploying complete CAD licenses for each remote worker represents a prohibitive cost

These constraints lead to a multiplication of obsolete local versions, excessive download times for large assemblies, and fragmentation of technical information across different systems and users.

Critical Issues for Manufacturing Companies

Beyond technical aspects, industrial organizations face four major challenges:

In this context, it becomes evident that traditional approaches are no longer suitable for the needs of modern industrial enterprises, particularly in remote work situations.

Modern Requirements for CAD Visualization and Collaboration

As work methods evolve, expectations regarding CAD visualization and collaboration solutions have significantly increased. An effective solution today must address multiple, often contradictory requirements.

Universal Accessibility

The first requirement of a modern solution concerns its ability to function independently of the user's computing environment:

• Compatibility with different operating systems (Windows, macOS, Linux)
• Operation on mobile devices (tablets, smartphones) for consultations on the move
• Independence from client workstation power
• No complex software prerequisites or specific plugins

This accessibility must be guaranteed without sacrificing the advanced functionality needed for professional exploitation of CAD models.

Enhanced Security

In a context where CAD data often represents the core of a company's intellectual property, security becomes a determining criterion:

• Protection against unauthorized copying of 3D models
• Granular control of access rights by user and by project
• Temporal limitation of access authorizations
• Complete traceability of consultations and manipulations
• Advanced know-how protection techniques (alienation, simplification)

These security measures must be implemented transparently for the user, without burdening work processes.

Optimized Performance

The fluidity of use directly conditions the adoption of a solution by technical teams:

• Rapid loading of voluminous assemblies (several gigabytes)
• Immediate responsiveness during manipulations (rotation, zoom, selection)
• Smooth display even for complex models (several million components)
• Optimization of data flows to minimize bandwidth consumption

Insufficient performance invariably leads to a return to traditional methods, canceling the expected benefits of the solution.

Collaborative Features

Beyond simple visualization, a modern solution must facilitate collaborative work around models:

• Measurement and analysis tools directly in the visualization interface
• Ability to create and share annotations and comments
• Comparison functions and change detection
• Generation of specific views and shared configurations
• Integration with existing communication tools

These multiple and sometimes contradictory requirements explain why so many companies struggle to identify a solution truly adapted to their specific needs for CAD collaboration in remote work.
