SLDPRT Files: How SolidWorks Teams View, Share, and Version Them
SLDPRT is SolidWorks' native part format — the source of truth for every component your team designs. The format isn't the problem. Keeping track of it is: shared drives fork versions, emailed copies go stale, and non-CAD reviewers can't open the file at all.
Sibe gives SolidWorks teams one place for parts: check files in and out directly in SolidWorks, track every version automatically, and share any part as a free public link that opens in the browser — no CAD license, no account needed.
This guide covers how to open and view SLDPRT files, and how to keep them organized once more than one engineer — or one revision — is involved. No servers, no VPNs, no admin hassles.
Open, View, Comment on SolidWorks Files and Share as a Link
- View and share SolidWorks SLDDRW files online as a live link
- Open files of any size in your browser, on any device
- Track revisions and control who sees which version
- Share with suppliers and customers, free unlimited web visitors
- No software installation, no server, no VPN
What an SLDPRT File Is
An SLDPRT file is a single SolidWorks part: the exact geometry plus the full feature tree behind it — sketches, dimensions, materials, and custom properties. It carries the design intent, not just the shape, which is what separates it from neutral formats like STP or IGES that you send outside the company.
That richness has a flip side: only SolidWorks opens SLDPRT natively. The moment a purchasing manager, client, or shop-floor supervisor needs to see the part, the file format becomes a wall.
How to Open an SLDPRT File
1. In SolidWorks. File > Open — it's the native format. You get the full feature tree and every configuration.
2. Without SolidWorks — eDrawings. Dassault's free viewer opens SLDPRT for basic viewing and measuring, but it's an install, and every reviewer needs it set up first.
3. In any browser with Sibe. Upload the part to Sibe's Web Dashboard and it opens on any device. Send a free public share link or QR code — recipients view the 3D model with no CAD license and no Sibe account. Reviewers pin comments straight on the geometry, so feedback lands on the part instead of in an email thread. That's how SolidWorks teams run design reviews without exporting a single screenshot.
The Real Problem: One Part, Many Versions
Opening a part is easy. Knowing which part is current is the hard part. On a shared drive, bracket.sldprt becomes bracket_v2_FINAL.sldprt, two engineers save over each other's work, and an assembly quietly references last month's geometry.
Sibe is a cost-effective Cloud CAD Document Management platform built for SolidWorks teams. Engineers check parts in and out directly in SolidWorks — the add-in locks a checked-out part so nobody overwrites it, and version control records every revision automatically. When files move or get renamed, references update so assemblies keep loading. Live in 30 minutes.
SLDPRT vs the Formats Around It
SLDPRT — exact geometry plus feature tree. The source of truth for design work.
SLDASM — the assembly that references your parts. See SLDASM files.
SLDDRW — the 2D drawing generated from a part or assembly. See SLDDRW files.
STP / STEP — exact geometry only, no feature tree — the standard way to share outside the company. See STP files.

1. What software can open SLDPRT files without SolidWorks?
Programs like eDrawings Viewer, FreeCAD, and Fusion 360 can open SLDPRT files without requiring SolidWorks, but will not transfer native features.
2. Can SLDPRT files be opened online?
Yes.UploadtheparttoSibe'sWebDashboardanditopensinanybrowser—shareitwithafreepubliclinkorQRcode,noaccountorCADlicenseneeded.
3. How do I share SLDPRT files with colleagues?
The fastest way is a share link. Upload the part to Sibe and send a free public link or QR code — colleagues and clients view the 3D model in the browser, no SolidWorks needed.
4. Is it possible to annotate SLDPRT files?
Yes. In Sibe, reviewers pin comments directly on the 3D model in the browser, so feedback stays on the geometry instead of in email threads.
5. Can I view SLDPRT files on mobile devices?
Yes. A Sibe share link opens in any mobile browser — recipients view the 3D model on a phone or tablet with no app install.
6. Are SLDPRT files editable in non-SOLIDWORKS software?
Editing can be done to solids but design trees are not maintained.You may need SolidWorks for full editing capabilities.
7. Can SLDPRT files be converted to STL for 3D printing?
Yes, software like FreeCAD or dedicated converters can export SLDPRT to STL.
9. Do SLDPRT files support assembly features?
No, assembly features require the SLDASM file type, not SLDPRT. Multi-body designing is possible with SLDPRT, however.
10. Is cloud storage safe for SLDPRT files?
Generic cloud drives store the bytes safely, but they don't understand SolidWorks — no check-out locks, no version history, and references break when files move. Sibe stores SLDPRT files encrypted, with check-in/check-out and automatic version control built in.
