Best Practices for Sharing CAD Files with Suppliers
Have you ever wondered what risks your intellectual property faces once your CAD files are shared with suppliers? For many SolidWorks users, sharing CAD files securely is a significant challenge, especially in a world where data breaches, theft, and unauthorized reproduction of designs are constant threats. Implementing precise and secure practices for sharing CAD data is not just beneficial; it is essential for protecting your intellectual property and ensuring efficiency in your supply chain.
Leaks of shared CAD files are a common problem, and many companies still lack the controls to prevent them. This guide dives into best practices for sharing CAD files effectively with suppliers. Whether you're managing large-scale collaborations or working with subcontractors, these actionable insights will set you up for success.
Why Sharing CAD Files Securely is Essential
Every time you share a CAD file, you expose your proprietary designs to potential risks like unauthorized copying, data breaches, and version control issues. This problem isn't just administrative; it's financial and legal. As Violetta Bonenkamp of CADChain explains, "Your intellectual property is the backbone of your business. Without secure sharing protocols, you’re handing out the keys to your competitive edge."
Here are the potential risks SolidWorks users face when sharing CAD files without proper protections:
- Loss of intellectual property due to unauthorized sharing or theft
- Version control errors that lead to manufacturing defects
- Legal liabilities from unprotected data access
- Compromised supplier relationships due to data mishandling
To mitigate these risks, adopting robust tools and workflows for CAD file management is crucial.
Safeguard your intellectual property while collaborating with suppliers.
Use tools like BORIS for SolidWorks to register your CAD files with a blockchain timestamp. Blockchain certificates give you tamper-evident, dated ownership records.

What Are the Best Practices for Sharing CAD Files?
Implementing secure CAD file-sharing practices ensures the reliability of your processes and protects your intellectual property. Here are six essential steps you should follow:
1. Use Role-Based Access Controls
Grant access to CAD files based on the specific roles and responsibilities of each supplier or contractor. Only provide the minimum necessary data. For instance, use a viewer-only mode for certain collaborators while allowing others to edit or comment directly within the CAD platform.
By restricting permissions, you reduce the risk of accidental or malicious design leaks. PDM systems and secure sharing platforms let you set these permissions within your workflow; BORIS for SolidWorks adds a dated ownership record of the files you register.
2. Share Files in Neutral Formats Whenever Possible
For external suppliers, providing designs in neutral file formats like STEP or IGES reduces compatibility issues and limits the exposure of proprietary design history. As a practice, avoid sharing native SolidWorks files unless absolutely necessary.
Sharing neutral formats simplifies collaborations while maintaining control over sensitive design data. Data can also flow the other way: when engineers download supplier models from part libraries, the TraceParts terms let part vendors receive their details for sales follow-up.
3. Incorporate Blockchain Certificates for Ownership Verification
Blockchain-enabled CAD protections offered by tools like BORIS for SolidWorks register a file fingerprint (hash) and a timestamp as a verifiable ownership certificate. This helps in disputes over design ownership by giving a tamper-evident, dated record of authorship.
As Dirk-Jan Bonenkamp puts it, "Blockchain isn't just an IT gimmick. It's a legally defensible framework that European courts increasingly accept as evidence of ownership." Learn more about securely sharing CAD files using blockchain.
4. Set Expiry Dates and Track Access Logs
Enable temporary access links and detailed activity tracking to ensure you have full visibility into who accessed your CAD files, when, and how. This strategy is invaluable when working with multiple vendors on iterative designs.
Secure sharing platforms and PDM systems let you review access logs and revoke access if necessary; BORIS adds a dated record of the file versions you registered before sharing them.
5. Provide Onboarding for Suppliers
Suppliers accustomed to traditional CAD workflows may resist modern collaboration tools. Conduct brief onboarding sessions to demonstrate how to interact with cloud-based platforms like secure portals for file sharing. Setting expectations early reduces friction and ensures streamlined communications. If your suppliers also use SOLIDWORKS, SOLIDWORKS Design 2027 lets you invite them to a task on your 3DEXPERIENCE platform with Read-only or edit access.
6. Utilize Awareness-Driven Licensing Agreements
Combine technological controls with legal protections. Automated licensing agreements embedded in your workflows ensure that suppliers use your CAD files strictly for agreed-upon purposes. Write these terms into your supplier contracts and NDAs, and keep a dated BORIS registration of the files you share so you can show what was handed over and when.
Gaining supplier agreement upfront limits ambiguity and reinforces accountability.

Common Mistakes to Avoid When Sharing CAD Files
Avoiding common pitfalls ensures your intellectual property and design workflows remain intact. Here’s what not to do:
- Sharing via unsecured email: Unencrypted email attachments expose designs to unauthorized access and tampering.
- Over-sharing: Providing excessive access or full design histories increases risks of IP theft.
- No auditing mechanisms: Failing to monitor who accesses your files can lead to preventable breaches.
Instead, use file-sharing platforms integrated with CAD tools to streamline access control and maintain a secure, transparent transfer process.
Closing Thoughts and Where to Go Next
Sharing CAD files securely isn’t just a challenge; it’s a necessity in today’s connected manufacturing ecosystem. Tools like BORIS provide the perfect mix of technological innovation and legal robustness to protect your designs effectively, especially for European SMEs. By following these best practices, you ensure smoother collaborations, fewer risks, and complete control over your intellectual property.
