Version Control for 3D files

In high-stakes industries such as automotive, robotics, defence and aviation, 3D design lies at the heart of engineering and product development. Whether they are engineering complex mechanical assemblies in SolidWorks or creating precise visualisations and components in Blender, modern teams work with large, intricate files. However, managing these files can be chaotic. When multiple engineers, designers and artists collaborate on the same project, traditional file-sharing methods quickly become ineffective, resulting in overwritten data, broken assemblies and lost hours of work. This is why integrating robust version control into 3D design workflows is no longer optional, it is essential.

The Reality of File Management in Modern CAD Teams

Traditionally, teams working with computer-aided design (CAD) tools and three-dimensional digital content creation (DCC) software have relied on shared network drives, local backups or cloud storage folders such as Dropbox and Google Drive. In order to prevent collisions, team members often resort to manual file-naming conventions, such as appending suffixes like '_v2_final_revised_FINAL.step' or manually locking folders to prevent others from accessing them.

However, these makeshift solutions create severe bottlenecks. For example, when two engineers modify the same SolidWorks sub-assembly simultaneously on a shared drive, one person's work silently overwrites the other's. Once files are overwritten or buried in convoluted folder structures, tracking who changed a specific dimension or why a particular design iteration was abandoned becomes nearly impossible.

The Limitations of Traditional PDM Systems

In an attempt to combat the chaos of file management, many engineering organisations turn to traditional Product Data Management (PDM) systems. However, while PDM solutions attempt to bring order to CAD data, they often introduce their own set of significant disadvantages.

• High Administrative Overhead: PDM systems typically require dedicated IT personnel to configure, maintain, and troubleshoot server infrastructures.
• Rigidity and Slowness: Traditional PDM workflows can be clunky and slow, forcing designers and engineers through cumbersome check-in/check-out loops that disrupt creative and technical flow.
• Vendor Lock-In: Proprietary PDM architectures often lock teams into restrictive ecosystems, making data migration difficult and inflating licensing costs.
• Siloed Workflows: PDM tools are built strictly for traditional engineering CAD files, making them poorly suited for modern multi-disciplinary pipelines that also incorporate 3D artists using tools like Blender.

For fast-moving teams in the automotive, robotics and aerospace industries, a system that slows down development or restricts flexibility defeats its own purpose.

Why a Git-Inspired Workflow Fits 3D Design

Decades ago, software developers solved this exact collaboration problem using Git-based version control. Using a Git-like workflow for 3D design offers significant advantages:

• Branching and Experimentation: Engineers and artists can create isolated branches to test a new mechanical component or design iteration without risking the stability of the master assembly.
• Complete History Tracking: Every commit acts as a secure snapshot, allowing teams to see exact changes over time, revert to previous states instantly, and audit the entire history of a project.
• Parallel Collaboration: Multiple team members can work independently on different parts of a complex robotic chassis or vehicle body without stepping on each other's toes.

However, standard Git tools are designed for text-based code, which makes them notoriously difficult for non-developers to use and means they are not well-suited to massive binary 3D files straight away.

Solutions built for Designers, Artists, and Engineers

To bridge the gap between powerful version control principles and the daily needs of creators of physical products, tools like Anchorpoint provide a streamlined solution. Designed specifically for the version control of large 3D, design and media files, Anchorpoint caters directly to artists, designers, architects and engineers who are not software developers. It offers everyone a Git-like version control workflow without the need for command-line knowledge or experience with developer-centric tooling.

Key capabilities of this client include:

• Open Compatibility and No Lock-In: Anchorpoint is fully compatible with Git and Lore. Teams can connect to existing servers, such as GitHub, GitLab, Azure DevOps, Gitea, self-hosted Git servers, or a Lore server ensuring complete ownership and control over where project files are hosted.
• Tailored for DCCs and CAD tools: The application integrates smoothly into workflows involving 3D DCC applications like Blender and heavy CAD tools like SolidWorks.
• Built-In Large File Handling: It features automatic configuration of Git LFS (Large File Storage) for massive binary files, solving one of the biggest hurdles of using Git with 3D models.
• Essential Collaboration Features: On top of version control, Anchorpoint adds critical usability layers including file locking (to prevent simultaneous conflicting edits on binary files), selective checkout, asset tagging, and review features.
• A Modern Alternative to PDM: For engineering workflows, it serves as a flexible, lightweight alternative to traditional PDM systems.

Anchorpoint recently released a beta version of a new client, Anchorpoint for Lore, which uses Lore. Lore is a version control system developed by Epic Games, the creators of Unreal Engine and can handle large amounts of data efficiently, load revisions in milliseconds, and upload large production files in a fraction of the time required by other solutions, such as Git and Perforce.

Conclusion: Moving beyond slow and restrictive workflows

In fast-moving industries such as aviation, defence, robotics and automotive, your tools shouldn't hold you back. Using legacy network shares or slow, restrictive PDM systems can stifle development, hinder cross-functional collaboration and increase the risk of costly design errors. Moving to a modern Git-based or Lore version control system with accessible tools enables engineering and design teams to protect their data ownership, collaborate seamlessly between 3D DCCs like Blender and CAD apps like SolidWorks, and remove administrative obstacles. By moving away from restrictive systems that slow you down, you can focus on what matters most: designing and building the future.
