The Short Version
Dropbox is a great tool for sharing documents that you don’t edit, but it wasn’t built to understand CAD. It has no concept of assembly references, no true file locking to prevent two engineers from corrupting the same part simultaneously, no version history, and no audit trail for engineering change control. Many manufacturers start with Dropbox (or Google Drive/OneDrive) because it’s already there, then discover the hard way that generic file sync creates version conflicts, broken CAD references, and compliance gaps.
Kenesto is purpose-built for CAD file management, with the simplicity of a cloud folder and the controls of real PDM. Kenesto also works with Office files, PDF documents, in fact, nearly all document types.
How Kenesto Compares to Dropbox
| Kenesto Built for CAD & PDM |
Dropbox General File Storage |
|
|---|---|---|
| Deployment | Cloud-hosted, purpose-built for CAD, event-driven | Cloud-hosted, general-purpose file sync |
| CAD-aware file locking | ✓Prevents simultaneous edits to referenced/assembly files | ✗Two users can edit the same file at once, risking overwrites and broken CAD references |
| Assembly/reference integrity | ✓Understands part-assembly-drawing relationships | ✗No CAD awareness; treats files as generic blobs |
| Version control | ✓Structured, unlimited version history tied to engineering workflow | ∼Basic file version history (30–180 days depending on plan), not CAD-aware |
| Dependencies / where-used tracking | ✓Yes | ✗None |
| Audit trail for compliance (e.g. ISO 9001) | ✓Yes | ∼Limited- general activity log, not engineering-change-specific |
| Sync model | ✓No syncing. Instead, event-driven file handling prevents unintended overwriting | ∼Local folder sync- large CAD assemblies can cause conflicting local copies |
| Access control granularity | ✓Full granular control including automatic expiration | ∼Folder- and file-level sharing permissions only |
| CAD system integration | ✓Works with AutoCAD, CATIA, CREO, Inventor, NX, Revit, Rhino, Solid Edge, SolidWorks and others | ✗No native SolidWorks/Inventor/Revit integration |
| Storage | ✓Unlimited | ∼Per TB fee |
| Pricing model | Pricing starts at $25/month for unlimited storage. Discounts for 10 or more licenses. | Low-cost, per-user storage plans — but not priced or built for engineering data control |
Why Manufacturers Switch
1
Dropbox doesn’t know what a CAD assembly is. Without true file locking, two engineers can open and save the same referenced part simultaneously, a common cause of corrupted assemblies and lost work.
2
Compliance risk. If you need an audit trail for ISO 9001 or customer quality requirements, Dropbox’s generic activity log doesn’t provide the structured revision/approval history auditors expect.
3
“It’s already free/cheap” is the wrong comparison. The real cost isn’t the Dropbox subscription, it’s engineering hours lost to file conflicts and rework.
4
Version issues can be very expensive if your suppliers are working from obsolete models or drawings.
