Overcoming File Management Challenges for Large CAD Files

Introduction

Imagine you’re deep into a critical engineering project, collaborating with your team on a massive CAD file, only to find that your coworker or teammate waiting for your change experiences delays that feel like forever, files overwrite each other, or references go missing. This is the daily reality for many in the Architecture, Engineering, and Construction (AEC) industry as they navigate remote work and digital transformation.

This article explores the journey many firms take—from trying SharePoint and Azure Files to finding better solutions—to manage large CAD files efficiently and ensure seamless engineering workflows in the cloud.

1. Why Doesn’t SharePoint Work for CAD Files?

With the success of Microsoft Office 365 and the integration of Microsoft Azure Active Directory, OneDrive and SharePoint are readily bundled with Windows 11. Naturally, these tools are the first solutions many firms try when transitioning to remote file access. The logic is simple: if it’s already there, why not use it?

However, SharePoint often falls short for the AEC industry, especially when dealing with large CAD files. Here’s why:

• Collaboration Bottlenecks: SharePoint struggles with syncing and saving large CAD files, causing delays and disrupting workflows. Imagine your coworker unknowingly opening a file before your changes have fully synced, potentially overwriting your updates or creating inconsistencies in a group of interdependent files.
• Incompatibility with Autodesk Software: Autodesk tools, a cornerstone of AEC workflows, don’t integrate seamlessly with SharePoint. This creates several issues: File Overwriting and Version Conflicts: Without proper file-locking mechanisms, multiple users working on the same file may overwrite each other’s changes, leading to inconsistencies and data loss.
• Data Integrity: External file references in Autodesk software create dependencies where a group of files must be treated as a single cohesive unit. Allowing different users to modify separate files within the group can lead to mismatched references or corrupted relationships.
• Remote Work Complications: As firms adopt remote work, SharePoint’s performance issues and frequent technical hiccups become even more apparent, straining operational continuity.

2. Azure Files: A Promising Solution or Another Roadblock?

When SharePoint fails, many firms turn to Azure Files, a server-less model of file server shares in the Azure Cloud. Azure Files integrates seamlessly with Azure Active Directory and offers features such as:

• Serverless SMB Shares: Mimicking the familiar on-premise file server setup.
• Cloud Authentication: Centralized and secure user authentication via Azure AD.
• Migration Support: Tools to facilitate the transition to the cloud.

On paper, Azure Files seems promising, but in practice, it introduces new challenges.

ISP Restrictions on Port 445

The SMB protocol, which Azure Files relies on, uses port 445. Unfortunately, many ISPs block this port, making file access impossible in some regions. This leads to:

• Operational Disruptions: Teams may lose access to essential files, halting work.
• Workarounds with VPNs: While Azure VPN endpoints can bypass this restriction, they add complexity and reliability issues, creating more frustration.

3. Is Returning to On-Premise File Servers the Final Answer?

Given the challenges with both SharePoint and Azure Files, it’s natural to wonder: Is reverting all the way back to local on-premise file servers the only viable solution? While on-premise servers offer familiarity and control, they come with significant drawbacks, including high maintenance costs and limited scalability. Not to mention, to work remotely, a VPN has to be used to get access to those large CAD files, which has many problems of its own.

Thankfully, there’s another way—a solution that bridges the gap between legacy file servers and modern cloud environments.

4. Introducing Triofox: A Different Approach

Triofox is an HTTPS-based file gateway designed to deliver large CAD files from Azure Files with exceptional performance and reliability. By using HTTPS-based file streaming, Triofox avoids the port 445 restrictions that hinder SMB protocols. It also offers:

• Improved Performance: Local device caching enhances speed and responsiveness, ensuring smooth workflows for AEC teams.
• Enhanced Workflow Support: Drive mapping and file locking capabilities are tailored specifically for CAD file engineering workflows, keeping your projects on track.

With Triofox, AEC professionals can overcome the limitations of traditional solutions and achieve secure, efficient file management.
