File Sharing for Engineering Teams

The design review is tomorrow. You need to send the updated CAD assembly, three revised technical drawings, the material specification sheet and the test report to the client engineering team. The files total 800 MB. Email is out of the question.

The Engineering File Sharing Problem

Engineering teams work with some of the largest and most complex file types in any industry. CAD assemblies, FEA simulation results, technical drawings, 3D models, PCB layouts, specifications and test reports are the daily currency of engineering work. These files are often enormous. A single SolidWorks assembly with all referenced parts can easily exceed 200 MB. A complete set of technical drawings for a product can hit 500 MB. Simulation result files routinely break the gigabyte barrier.

Email cannot handle these files. Most corporate email systems cap attachments at 25 MB, which is a fraction of what engineering teams need to share. Even services that handle larger files often struggle with the specialized file formats that engineers use. DWG, STEP, IGES, STL, SLDPRT and dozens of other formats confuse consumer-grade file sharing tools that were designed for documents and photos.

Engineering projects also involve many external collaborators. Contract manufacturers, testing labs, certification bodies, client engineering teams and supplier quality departments all need access to project files at various stages. Most of these external parties do not have access to your internal PLM system or cloud storage. Granting them access requires IT tickets, license purchases and onboarding processes that slow down projects by days or weeks.

Version control adds another layer of complexity. When a design revision goes out, everyone needs to know exactly which version they are looking at. A test report based on Rev B of a drawing is meaningless if the design is now at Rev D. Clear versioning and descriptions attached to file deliveries are essential for engineering workflows.

What engineering teams need is a file sharing solution that handles large files reliably, works with any file format, does not require recipients to create accounts and provides clear context about what each delivery contains.

How Engineering Teams Use EasySend

1. Upload project files - drag CAD files, technical drawings, specifications and test reports onto easysend.co. Chunked uploads handle large files without browser crashes or timeouts.
2. Add a description with version notes - include context such as "Bracket assembly Rev D - updated per ECN-2026-0142, includes FEA results and updated tolerance stack" so recipients know exactly what version they are receiving and why it changed
3. Set a custom URL (optional) - create a clean link like easysend.co/project-x-rev-d for easy reference in emails and meeting notes
4. Share the link - email it to the client engineering team, text it to the contract manufacturer or post it in the project channel

Why EasySend Works for Engineering Teams

• Large file support - chunked uploads handle CAD assemblies, simulation results and test data that would choke email systems and many file sharing services. Files up to 1 GB are free. Premium handles up to 10 GB for complete project packages.
• Any file format - DWG, STEP, IGES, STL, SLDPRT, SLDASM, IPT, IAM, CATPART, PRT and every other engineering file format works without conversion or compatibility issues. EasySend does not care what the file extension is.
• Bundle multiple files - send the CAD assembly, all referenced parts, the technical drawing set, the BOM and the test report under one link. Recipients get everything they need in one place instead of hunting through multiple emails.
• Version notes in descriptions - add revision numbers, ECN references and change descriptions to every delivery. Recipients always know which version they are looking at and what changed from the previous revision.
• Download All as ZIP - recipients grab the entire package with one click. No downloading 15 individual files from a list.
• No recipient accounts - contract manufacturers, testing labs and client engineers click the link and download. No account creation, no app installs, no IT department involvement. This removes days of friction from external collaboration.
• Password protection - gate access to proprietary designs, trade secret documentation and confidential test results. Share the link via one channel and the password via another for security.
• API for automated workflows - integrate EasySend into your release process. The REST API lets you upload files and generate share links from scripts, CI/CD pipelines and PLM system hooks.

Common Engineering Use Cases

• Sending CAD assemblies and technical drawings to contract manufacturers for quoting
• Sharing test reports and certification documents with client engineering teams
• Distributing updated specifications and BOMs to suppliers
• Delivering FEA and CFD simulation results to design review stakeholders
• Sending PCB layout files and Gerber packages to board fabrication houses
• Sharing prototype photos and test data with remote team members

EasySend handles the large, complex files that engineering teams work with every day. Chunked uploads prevent failures. Bundle descriptions provide version context. And external collaborators get access without accounts, app installs or IT tickets. Upload your project files, add your revision notes and share the link.
