GrabCAD Workbench shut down in June 2023. Here are the best alternatives for sharing and reviewing CAD models in 2026, by budget and use case.
According to the official announcement on GrabCAD's blog, Stratasys permanently closed GrabCAD Workbench on June 1, 2023 at 12PM GMT, the free CAD sharing and review platform used by hundreds of thousands of engineers. The shutdown had been announced ten months earlier, in August 2022. Entire teams were left without a tool to share STEP files with non-CAD collaborators. The stakes are not marginal: the 3D CAD software market was worth about USD 10.38 billion in 2022 and is projected to reach USD 17.34 billion by 2030 according to Grand View Research, and imperfect interoperability between tools alone costs more than one billion dollars per year in the U.S. automotive supply chain (NIST study). Here are the alternatives available in 2026, ranked by use case.
Stratasys acquired GrabCAD in 2014 to accelerate its 3D printing offering. Per GrabCAD's own announcement, the shutdown was part of a strategic pivot toward additive manufacturing solutions (GrabCAD Print, GrabCAD Shop), the free CAD-sharing service no longer fit that direction. Users had until June 1, 2023 to export their data before all files stored in Workbench were permanently deleted.
OmniView 3D replicates the core logic of GrabCAD Workbench: upload your STEP or IGES file, get a shareable link, send it to your colleagues or clients. The recipient sees the interactive 3D model in their browser, no CAD software required. Key advantages vs GrabCAD: EU hosting (AWS eu-west-1, Ireland, GDPR), iFrame embed, hologram mode, and a sustainable free plan. Every model is private by default; you only publish a link if you choose to, and it stays revocable at any time. For the full method, see our guide on how to share a STEP file without CAD software in 60 seconds.
Onshape (PTC) is a full cloud CAD tool with version management, branches, and granular permissions. It's the closest solution to GrabCAD from a PDM perspective, but it's also a full CAD application. Pricing: from $1,500/user/year. Right for teams wanting to migrate entirely to cloud CAD. If your real need is private sharing rather than cloud CAD, compare the Onshape alternatives for private 3D sharing first.
Google Drive and SharePoint store and share STEP files but don't open them. Your recipient gets a file they can't visualize without CAD software. Useful for sharing between engineers, useless for sharing with non-equipped clients or subcontractors.
3DViewerOnline is an online viewer that supports STEP, IGES and several CAD formats. Its interface is more complex than OmniView 3D, hosting is in the United States, and there's no iFrame embed mode. A fair option for simple visualization, less suited to commercial or e-commerce sharing.
| Need | Recommended tool | Pricing |
|---|---|---|
| Share a model with a client, no software required | OmniView 3D | Free (Starter plan) |
| Full CAD version management (cloud PDM) | Onshape (PTC) | From $1,500/user/year |
| File sharing between already-equipped engineers | Google Drive / SharePoint | Included if already subscribed |
| Spare parts catalog for field technicians | OmniView 3D | Free to $179/month excl. tax depending on volume |
| 3D embed on an e-commerce product page | OmniView 3D | Free to $179/month excl. tax depending on volume |
No. Stratasys permanently closed GrabCAD Workbench on June 1, 2023, and all files stored in it were deleted on that date. Don't confuse the products: the GrabCAD Community (model library) and GrabCAD Print are still active; only the Workbench sharing-and-review tool was shut down.
To replicate Workbench's core (upload a CAD file and share it by link with people who have no CAD software), OmniView 3D offers a free Starter plan: native STEP and IGES, a shareable link the recipient opens in the browser with no account, and EU hosting. For full PDM-style version management, Onshape is closer but paid.
Upload your STEP or IGES to a web viewer such as OmniView 3D: in under 60 seconds you get an interactive link your client or supplier opens in any browser, with no SolidWorks, CATIA or FreeCAD. The model stays private by default and the link is revocable.
No. Users had until June 1, 2023 to export their data; after that date Stratasys permanently deleted all files hosted in Workbench. You'll need to start again from your original CAD files to host them on a new platform.
